The mapping of noise in Iaşi City – the synthesis of the results In 2004, INCERTRANS prepared Strategic Maps of Noise for Iaşi City. This activity was performed in phases, following the provisions of specifications and in compliance with legal rules in the domain. So, these maps have been prepared through measurements on the site and theoretical calculations on the entire area of the city. For every source of noise it has been done a map, for those two acoustic parameters envisaged in Government Decision no. 321/2005, respectively Lden and Lnight. These maps have been attached with a complete report which describe the phases of the acoustic mapping. The synthesis of noise mapping is the action to present the assessment of the obtained results follow to preparing og every strategic map of noise and of the associated data regarding exposure to noise for sources of noise: Road traffic Railways traffic Industrial noise Air traffic Map of noise regarding road traffic in Lden regime According to results obtained followinf the preparinf of map of noise for road traffic due to geometrical characteristics of streets but also to traffic values currently available there are been highlighted the following areas: - it is observed the reaching of the threshold of 70 dB for Lden, for the following streets: Carol I Blvd. Şos.

Andrei Street Galateanu Street The exceeding of limit value is due mainly to high values of traffic flows, presence of heavy traffic on a part of streets of the urban network streets, but also to road paving. Railways traffic – CFR + tram: According to data obtained following the preparing of noise map for railways traffic there is observed that the task of noise Lden exceeds the value limit with (0-5 dB) at several buildings on Arcu Street (up to Gavril Muzicescu Street) and Cuza Vodă Street (up to Rond Tg. Cucu). Action plans to reduce levels of noise in Iaşi City 22 According to data obtained following the preparing of noise map for railways traffic there is observed exceedings of Ln with 5-10 dB of the limit value in the following areas: - beyond station up to Alexandru cel Bun Passage at 6 buildings; - at 4 buildings on Luca Arbore Street; - at several buildings on Arcu Street (up to Gavril Muzicescu Street) and Cuza Vodă Street (up to Rond Tg. Cucu). The value of task of noise Ln exceeds with 0-5 dB the limit values in the following areas: - at several buildings on Luca Arbore Street and beyond on Sdl. Canta; - beyond the station up to Alexandru cel Bun Passage at several buildings on the both sides of railways; - at several buildings on Pădurii Street and Tătăraşi Street; - at 4 buildings on Aurel Vlaicu Street; - at 3 buildings on Vasile Lupu Street; - at several buildings on Strămoşilor Street, Dacia Blvd and Alexandru cel Bun Blvd. The total number of persons exposed to levels which exceeds the limit values is 299 persons for Lden. The total number of persons exposed to levels which exceed the limit values is 299 persons for Lden and of 5015 for Lnight. Industrial activities According to data obtained following the preparing of noise map for industry source there is observed no exceeding of the limit value for L den. According to data obtained following the preparing of noise map for industry source there is observed no exceeding of the limit value for Ln. Air traffic: According to data obtained following the preparing of noise map for air traffic there isn’t observed any exceeding of limit value for L den. The total number of persons exposed to levels which exceed the limit value for Lnight is 1514 persons. These persons live across the following streets: Aeroportului, Cpt. Protopopescu, Moţilor, Aviaţiei, Aterizaj, Avionului, Holboca, Nisipari and Marginei. There is necessary that population to be informed and warned about which are the levels of noise which human body can support, what means a certain theshold of the level of noise and especially to what dangers are they exposed due to prolonged exposure to a noise of high intensity (fig. 2). Action plans to reduce levels of noise in Iaşi City 23 Level of pain Range of noise specific for human social activity Level of audibility Fig 2 – The levels of noise for different sources of noise Negative effects of noise The sound/noise can be generated by several types of sources and it plays an important positive role in people’s life (communication, culture), but also produces negative effects as: Discomfort The noise can be defined as the sound that is perceived as disturbing by human. The way how people react to noise exposure doesn’t depend only by its intensity but also of what it represents for the person. The noise has a subjective meaning, it is not only a variation of pressure. Sleep disturbing A good sleep over the night is a necessary condition for well-being. Sleep disturbing is one of the main reason to claim the noise. The main phenomena are: the difficulty of falling asleep, unwished premature awakening, the difficulty to sleep again after a person has awaken and changes in the phases of sleep. People can claim also secondary effects of sleep disturbing as: the reducing of sleep quality, the fatigue, depressions, the reducing of productivity and attention. The psychological effects are: the rise of blood pressure, the rise of puls, contraction of blood arteries, changes of breath rythm, cardiac arrhythmia. Action plans to reduce levels of noise in Iaşi City 24 Other adverse effects Hearing affecting – the persons who work in certain industrial domains have a high risk if there are not taken preventive measures for protection. There is a growing concern regarding noise exposure in clubs, disco, restaurants and other locations of this type. The interference with talking and other means of communication The noise may mask the voices (talking), radio listening or TV listening and other sounds, inclusively music that people want to hear. Mental health The noise of ambiance is not considered a primary cause, but is possible to be a factor to accelerate or to intensify. Work productivity It has been demonstrated that noise of ambiance can increase the performance in routine work, but can decrease this performance in activities which require attention and memorization. Learning process This can be affected, also the process of reading can be affected, motivation can be reduced and all these affect the accomplishment of complex tasks. Social behavior The studies show that noise exposure can make people to be non-comunicative and taciturn, less understanding and available to help other people or neighbors. It’s less probable that the noise generates agression, but noisy environments induce a higher state of uncertainty. Changes of noise Taking into consideration the rythm and current trends of development, the studies show that the noisy environments which will not benefit of measure to limit the noise exposure will be more deteriorate in the future. This because: - the increase of number and the power of noise sources and the increasing of their use (especially transport); - geographical spreading of noise sources in city’s development, new transport infrastructure and touristic activities. – the expansion of noise in time, especially in early morning and night and in week-ends. The limits on certification of noise sources imposed by EU policy shouldn’t seem yet to have effect in reducing the global levels of noise in urban areas. The level of environmental noise in a city tends to be higher when the transport structure is concentrated. While new models of vehicles are increasingly silent, the level of traffic increases. New buses or trams should be more silent, but also their infrastructure should Action plans to reduce levels of noise in Iaşi City 25 be improved. Many of central streets of the city have reached their saturation regarding the traffic, almost daily congested and with increasingly low speed of traffic in the entire day. In Iaşi City, the noise is made mainly by road traffic and less by railways traffic and air traffic. The impact on human health can be direct on hearing and on whole body. The impact on ear can lead to acute disorders resulted as a prolonged action of high noises which determine trauma of eardrum or medium ear, expressed as clogging or breaking of the eardrum, bleeding, deafness etc. At small children the noises of high intensity determine several disorders with negative consequences for further body’s development. In the case of impact on the whole body the penetration of noise is done not only through acoustic nerve but also through skin, muscles, bones etc. So, it occurs the increasing of pulse, of blood pressure, of amplitude and frequency o the breath, the decrease of the attention, rapid fatigue, headache and nervous asthenia. Among the disorders caused by noise can be: neuroses, psihastenia, gastritis, gastric and duodenal ulcers, colitis, diabetes, hyperthyroidism, etc. 2.7. The official synthesis of pulic consultancies organized in compliance of provisions of art. 11 paragraph (8) and (9) of Government Decision 321/2005, republished The preparing of action plan to reduce the acoustic pollution has to take into consideration of public consultancies. The process of preparing the action meant to reduce and to eliminate the noise is a long term procedure. The public information offers the opportunity of citizens’ participation to prepare the action plan.The experience shows that the acceptance of the methods and measures is higher when citizens were informed from the beginning regarding action plans. For public information the map of noise and conflict noise were shown on official site of Iaşi City Hall, following to that action plans to be published for public consultancy. On 19th of June 2014 it was hold at Iaşi City Hall the meeting of public debate of action plans to reduce the noise for Iaşi City. To this meeting were participated representatives of directions and services of City Hall, of companies and services subordinated to Local Council and representatives of other institutions with responsabilities in noise management, representatives of economic agents, mass-media and owners associations (see Annex 8 – Minutes no. 55587/19.06.2014). As a conclusion that resulted from the discussions it was the idea that in the future the strategic maps of noise, toghether with action plans should constitute an efficient instrument which can be taken into consideration in preparing of zonal urban plans and detailed urban plans and also in update of general urban plan. Urban plans can be adjusted so as to assure that are not built new buildings in the areas with high impact of Action plans to reduce levels of noise in Iaşi City 26 noise and to assure that no new enterprises which generate noise are placed close to quiet or residencial areas. 2.8. Measures in force to reduce noise and ongoing projects Road traffic Curretntly there are projects to improve and repair the streets which contribute indirectly to reducing of noise.

Air traffic There are no completed or ongoing projects/programs to reduce the noise. 2.9. Actions to be taken by the authorities in the following 5 years, inclusively the measures to preserve quite areas This chapter is divided into three separate sections designed for action plans prepared for every source of noise: road traffic, rail traffic and industry. The most effective tool to prevent noise problems is good planning. It is a long-term instrument that will not solve the immediate problems, but based on strategic noise maps, urban plans can be adjusted to ensure that no new buildings are built in areas with a high impact of noise and and to ensure that no new enterprises/business which generate noise are placed close to quiet or residential areas. The planning process can also be used to improve the environment in the area, in this way ensuring that long-term use of land is changed. It can be decided for example that a residential area with high impact of noise should change gradually in an area with a less sensitive character, for example small offices and workshops. When building new roads, railways, airports and industrial units it has to comply with the legislation in force so that new investments should be subject to a careful analysis of the environmental impact. Road traffic For road traffic, new roads should always be planned so as not to increase the number of homes and people with discomfort caused by noise. This can include noise reduction measures along the new road (such as noise barriers) or expropriation of houses. However, designing a new road should be based on a traffic modeling study, different scenarios to verify and prove the the overall advantage of the new road by estimating the size of impact on traffic and environment (including noise and air pollution). Traffic modelling is an important tool for planning and irreplaceable. It is necessary both for traffic analysis (the calculation of traffic volume and the establishing of its origins, its destinations and its link) and for the traffic prognosis (the estimation of the impact of proposed Action plans to reduce levels of noise in Iaşi City 31 measures, as for example a new road or speed restriction). It is very important to calculate the impact of planned measures before they are prepared. For this it is necessary to prepare traffic studies with specialized soft for road traffic modelling. For existing roads, the reducing of noise can be divided in three types: reduce the noise at the source mitigate the propagation path measures around the receiver Reduce the noise at the source There is a large range of possible measures. Some of them have only local effects, other have to be implemented in overall urban concepts. The basic approach to reduce the noise of road traffic consists in: Measures to avoid or to reduce the noise of vehicles traffic Measures to concentrate the inevitably traffic or to divert it toward less sensitive areas Measures to make remained traffic more consistent Prevent the noise of vehicles traffic - Technical measures on vehicles and tires: technical measures are a very important topic with a high potential to reduce the noise. The standards are set by the European Union. The municipality may introduce buses, vehicles to collect the garbage which produce less noise etc. - Urbanism: is desirable to separate noise sources from residential areas. On the other hand, the density and diversity of the various uses have some effect on the behavior of the people in terms of mobility. The experience shows that motor traffic is reduced if it is possible to shop or work close to home. Therefore, urbanism plans should fiind a compromise between the separation of incompatible uses and combination and concentration of compatible uses as housing, shopping and unpolluting activities so as to reduce the need for transport. For new resindential areas should be ensured routes of public transport. In planning new industrial areas should be taken into account not only the direct impact but also the anticipated routes of heavy freight vehicles. - Promote public transport: encouraging public transport can help to reduce traffic emissions. Although trams and buses can be noisy, their specific noise emissions (for example reported to a capacity of 1,000 people per hour) are much smaller than emissions from cars. The measures that can be considered are quality transport improvement, for example the increase of the service by introducing special lanes for buses and traffic light system with priority for public transport in intersection. - Encouraging the use of bike: promote non-motorized means of transport is very useful in Action plans to reduce levels of noise in Iaşi City 32 cities. Several European cities like Amsterdam, Copenhaga and Gent have an extensive network of bicycle tracks, so over 20% of all trips are made by bicycle. In these cities the byke is widely accepted means of transport, which help to reduce the traffic of vehicles.So, the municipality should consider the possibility to set tracks for byke, especially in congested areas with a high density of traffic. - Reduce traffic (at destination): introduce parking charges or maximum parking period (for example 2 hours) to park on street can reduce the traffic, especially that due to commuters which will prefer public transport. This generates less traffic (also less noise) and has as secondary effect the existence of several parking spaces for more valuable purposes and reducing the need for space. Other possibilities are road taxes combined with systems to control the access, which to limit the number of vehicles that enter in the center of the city. - Park and use public transport (park&ride): A „park&ride” (parching spaces with access to public transport lines) increase the attractiveness of public transport, especially for the commuters. In general, these parkings should be built on the main streets of penetration in the city, but it involves new public transport lines which to link these parkings and the main points of interest of the city. -Reduce the heavy freight traffic within the city by installing of logistic centers and coordinated systems for goods distribution. Traffic concentration or its diverting towards less sensitive areas - Traffic concentration on main streets and traffic calming on secondary streets: the concentration of traffic on upper categories of roads/streets can be a very efficient method to reduce because the differences in the level of noise depend of percentage differences of traffic volume. Disadvantage – excessive congestion of some arteries also very congested (especially at peak hours) whose capacity of traffic would be exceeded, leading to congestion. - Divert traffic towards less sensitive areas: it is possible to divert traffic on a sensitive road, with several inhabitants, towards a less sensitive road, for example from an industrial area or a ring road. This can reduce both total volume of traffic and the share of heavy traffic. - Classify the network of streets: as a result of concepts and above mentioned measures it can be defined a network of main streets/roads with sufficient capacity. Especially for heavy freight vehicles it should be a routing system wich to follow towards the network of main streets/roads. On secondary remained streets/roads should be applied traffic calming, for example speed restrictions. The proper approach of remained traffic, which can not be avoided or diverted (usually the largest part) - The surfaces of roads/streets: Good surfaces have a high potential to reduce the noise. Although, normally there is not possible to be simoultaneously replaced all damaged surfaces, the action plan should set a list of priorities, so as the Municipality be able to repair first those surfaces which have the highest level of noise and the highest number of affected persons. On roads/streets with higher limits of speed it can be usefull special surfaces open porous asphalt. Action plans to reduce levels of noise in Iaşi City 33 - Measures to improve and to homogenize the traffic flow: the roundabouts can help to reduce the speed, to harmonize traffic flow, to reduce the jams and the number and the gravity of traffic injuries. Traffic light systems with computed synchronization which depend of traffic volume can reduce the number of accelerations and stops (green light). At night, the traffic lights can be turned off at intersections with low traffic intensity. - Overall concept for traffic management: There are possible a lot of measures to influence noise emissions of traffic vehicles. For example, the limitation of speed can considerably reduce the level of noise and can move the traffic on other streets. One way streets can reduce the volume of traffic but can determine higher speeds. The forbidding of heavy freight vehicles on a certain road/street can generate problems on the alternative streets. Therefore it is usefull to be ellaborated an overall concept which to take into acount both the level of noise and the number of affected persons and the requirements of an effective network of streets. - Redesign the streets: Another possibility is to change the allocation of cross-section of the street. Leaving more space for trams, buses, cyclists and pedestrian it may require the use of public transport or non-motorized traffic and can increase the distance between the source of noise and facade. The experience shows that better proportion of vegetation planting can make population to feel more confortable, even there is possible not to exist measurable differences of noise level. Mitigate the path of propagation Acoustic barriers or ground banks can lead to a significant reduction of noise. The barriers placed either by the roadside or near the houses which follow to be protected. The structure of built areas and buildings alignment may also shield the buildings from areas located behind them. Therefore, the planning should follow enclosed structures, without openings between buildings. The acoustic requirements of an phonic barrier are very simple: - the barrier has to be as high as possible - the barrier has to be compact, without gaps and leaks - the surface mass of the barrier should be at least of 25 kg/m2 only, excluding the support construction - it should be avoided the reflections to the opposite side of the road (absorbant surface). Measures around the receiver The level of noise inside the houses can be improved by isolation of the facades and possibly by (re)construction of the roof. The most critical components are normally the windows. It can be installed new windows with soundproof glass. To ensure good results it is very important to carefully examine the building and to identify and prioritize the the paths of noise transmission. The procedure consists in calculation of the noise inside the Action plans to reduce levels of noise in Iaşi City 34 building in different rooms. The method of calculation is described by ISO 12354 standard „noise transmission through the facades of buildings”. For Iaşi City the main cause which generate noise is the high values of traffic on above mentioned arteries and especially the heavy traffic which tranzit some streets. To reduce these values of traffic it is imperative to complete the building of city ring in Northern and Eastern part of the city. In this way the values of traffic of city’s streets will be largely reduced. Streets with higher speed and capacity geberates higher levels of noise which affect larger areas. To lower speeds achieved in most part of urban and sub-urban areas of Iaşi City, the main sources of noise are the change of speed, stop and start on congested streets. The congestion can reduce the speeds during the daylight, especially in central area. There is a trend to increase the traffic even during this period of the day, in which the congestion is not so high. It can be taken into account different aspects of noise generated by road traffic: continous noise of congested traffic and average noise or background noise to which humans are exposed, several times, on a long time ; congested traffic, marked by repeated starts and stops, where is more important the vehicles acceleration and isolated noises and also the noises produced by heavy vehicles crossing on oscillation of level. The considered measures are theoretical, a real image of the effectiveness of the measures being achieved only after the monitoring of the measures. Assumptions A. The volume of road traffic in Iaşi City is kept constant (unless otherwise is specified in the Action Plan). B. The City Hall can intervene in any area affected by noise. C. The estimated budget to reduce the noise is not limited, the decision regarding financial limits remains the task of Iaşi City Hall. D. The buildings and the topography around the areas affected by noise remain unchanged. Action Plan 1 (PA1) Under this action plan, beside general consideration made at the beginning it is considered that Iaşi City Hall will apply the project of traffic management, envisaged by the Integrated Plan of Development for Growth Pole Iaşi. These projects consist in: Prepare a Sustainable Urban Mobility Plan Complete the implementation of traffic management system Action plans to reduce levels of noise in Iaşi City 35 Intermodal Transportation Center – Iaşi Bus Station Improve the link between the Intermodal Transportation Center – Iași Station Build byke tracks towards neighboring villages of Iaşi Electronic systems to improve the mobility in Iași Metropolitan Area (ticketing, public transport prioritizing, parking management, citizens’ informing). The aim of these projects of traffic management is to reduce the time of travel between two points of the city, whatever of hour, to lead to elimination of the accelerations and sudden braking, so common in terms of congested traffic. The estimated cost of these measures is 112,000,000 lei. Action Plan 2 (PA2) Action Plan 2 consists in reducing as much as possible of the number of heavy vehicles with mass over 3,5 t, on the network of streets of the city, by completing the ring road in Northern and Eastern part of the city. The advantages of a area of forbidding are: 1. reducing of noise and vibrations due to heavy vehicles; 2. additional charges to City Hall budget heavy vehicles entry in city; 3. fleet renewal by public transport operators in Iaşi. The estimated cost in order to build the ring road is 16,000,000 lei/km. Action Plan 3 (PA3) Action Plan consists in replacing the current surface of the streets with one with noise absorbing properties, which can reduce the level of noise from the affected area by the change of the asphalt up to 5 dB. Of course, this method has its advantages and disadvantages but the effects on acoustic background of the area are immediately felt. In the next period it is envisaged the improvement of streets infrastructure in industrial area of Iași City. The estimated cost of these measures is 100,000,000 lei. For noise reducing to be as large as possible it is necessary to be applied all 3 action plans so as the number of inhabitants to be affected by the levels of noise above limit values to be as small as possible (ideally 0). The combined application of these 3 proposed plans represents the recommended alternative of the developer of this study in order to increase the effects to reduce the noise in the city. Action plans to reduce levels of noise in Iaşi City 36 The number of persons affected by the level higher than the limit value, after the combined application of PA1, PA2, PA3 – Lden dB band 55-60 60-65 65-70 70-75 > 75 No. de persons* 356 581 632 108 4 * The number of persons affected by noise is expressed in hundreds.

In those areas where even after the application of measures to reduce noise for Lden > 65 dB, respectively Ln > 50 dB we propose a passive protection. It is indicated to start a program of “changing the windows”, first for the buildings which are situated along the main streets for which, even after the application of the measures of reducing , the level of noise Lden > 70 dB, respectively Ln > 65 dB. Action plans to reduce levels of noise in Iaşi City 37 Railway traffic – CFR + tram Currently the railway traffic cause the exceeding of the noise limit value in certain areas, especially near the central station but also on some non-modernized section of infrastructure of tram. Below are listed various measures which can be applied to reduce the noise due to railway traffic. The most effective tool to prevent noise problems is good planning. It is a long-term instrument that will not solve the immediate problems, but based on strategic noise maps, urban plans can be adjusted to ensure that no new buildings are built in areas with a high impact of noise and to ensure that are not places new enterprises near residential or quite areas. The planning process can also be used to improve the environment in the area, in this way ensuring that long-term use of land is changed. It can be decided for example that a residential area with high impact of noise should change gradually in an area with a less sensitive character, for example small offices and workshops. When building new roads, railways, airports and industrial units it has to comply with the legislation in force so that new investments should be subject to a careful analysis of the environmental impact. Measures to reduce the noise for railway traffic are in most part the same as for the roads. Good planning is essential. This fact is especially important around existing railways. A classic dilemma is that in urban areas located near railway there is usually unused land which can be purchase at a cheap price (because is close to railways). This land is bought by a contractor which starts immediately to built residential buildings. The new buildings are exposed to noise and vibration generated by trains. It is recommended to be included in rules and legislation some provisions regarding the minimal distance and the maximum level of the noise for new investments near a railway. Issues that require improvements There are several issues which lead to the existance of a number of persons affected by noise due to railway traffic: - an old fleet of trams and trains having mainly braked shoes system; - a non-improved railway infrastructure; - the lacks of periodical maintenance works by rail rectification; - the lack of acoustic protection measures (panels). The reducing of noise can be devided in three types: reduce the noise at source mitigate the path of propagation Action plans to reduce levels of noise in Iaşi City 38 measures around the receiver Reduce the noise to source An empirical rule for trains is that the noise of the locomotive is one dominant at a speed of train up to 30-40 km/h, after that the noise wheel/rail replace it and is dominant up to very high speeds (more than 200km/h), when it starts to prevail the noise produced by turbulence of air flow. For romanian trains, especially the freight ones, the passing from the noise of locomotive to wheel/rail noise is produced to even a lower speed. This fact is true in part because the romanian freight trains are relatively long, but especially because the bad state of the wheels and rails. Freight wagons are equipped with iron braked shoes. These brakes fray the surface of the wheel generating the so-called „straight sections” because the wheels are blocked during the braking process. The noise can be significantly reduced if the wagons are upgraded with braked shoes of composite materials, which can lead to reducing of rail use. The railway system is used only by a small number of companies. It could be possible to be defined standards regarding the emissions for trains which travel in main railways. Also, the reducing of noise generated by trains traffic can be achieved by: the reducing the noise issued at the contact rail – wheel through: the rectification of wheels and rails; the value of reducing depends on the cadence of rectification, previous European studies indicating a worsening of 0,8 dB of the acoustic level after the moment of the rectification for every year of delaying of process re-playing. The main issue consists in the lack of control of Iaşi City Hall on freight and passengers transport operators in order to impose some measure of periodical rectification. Neither the rectification of rail is not the duty of Iaşi City Hall, an investment in necessary equipments for this activity being big and ineffective to be done, unless at central level S.N.C.F.R. In change, the Municipality should be involved in tram network rehabilitation. the reducing of noise and vibration of the wagons and locomotives by their replacement with more silent vehicles; this measure can not be applied by Iaşi Municipality, it is the responsability of S.N.C.F.R. the municpality should ensure the necessary funds for trams fleet renewal. The reducing of the speed in the areas affected by the noise; this measure can not be applied by Iaşi City Hall, being an internal decision of S.N.C.F.R. The Municipality should establish the speeds for different sections of trams traffic. Mitigate the path of propagation The acoustic barriers can significantly reduce the noise. The barriers should be placed Action plans to reduce levels of noise in Iaşi City 39 either near the railways, or near the houses which following to be protected. The structure of built areas and the alignment of buildings may also shield the buildings in areas behind them. Therefore, planning should aim enclosed structures with no openings between buildings. The acoustic requirements of a phonic barriers are very simple: - the barrier has to be as high as possible - the barrier has to be compact, without gaps and leaks - the surface mass of the barrier should be at least of 25 kg/m2 only, excluding the support construction - it should be avoided the reflections to the opposite side of the road (absorbant surface). Measures around the receiver The level of noise inside the houses can be improved by isolation of the facades and possibly by (re)construction of the roof. The most critical components are normally the windows. It can be installed new windows with soundproof glass. To ensure good results it is very important to carefully examine the building and to identify and prioritize the the paths of noise transmission. The procedure consists in calculation of the noise inside the building in different rooms. The method of calculation is described by ISO 12354 standard „noise transmission through the facades of buildings”. Through this method it can be determined the contribution to levels of internal noise through different component of the building. The total level is calculated by summing of the contributions.

The volume of railway traffic in Iaşi City is kept constant (if otherwise is not mentioned in Action Plan). B. The City Hall could interven in any area affected by noise. C. The budget for reducing of noise is not limited, the decision concerning financial limitation is the task of Iaşi City Hall. D. The buildings and the topography around the areas affected by noise remain unchanged. Action Plan 1 (PA1) In this action plan, beside the general considerations made at the beginning, it is considered that Iaşi City Hall will continue and complete the works for upgrade of tram infrastructure. The estimated cost of this measure is 15,000,000 lei. Action Plan 2 (PA2) Action Plan 2 consists in the renewal/upgrading of trams fleet owned by RATP Iaşi. The estimated cost for upgrade a tram is about 2,250,000 lei. Action Plan 3 (PA3) Action plan consists in installing soundproofing panels with a height of 2,5 m on the section Central Station – ACB Passage. This soulution can be applied by Iaşi City Hall, but it needs a very good cooperation from S.N.C.F.R. side because, to be effective the panels have to be placed near the rail, in the area under the responsability of railways. Iaşi City Hall can financially support these measures but can not implement them without the support, at least for obtain the approval, of railways company. Generally, the applying of principle „the polluter pays” imposed that S.N.C.F.R. to pay the entire costs of using soundproofing panels. The estimated cost of these measure is 340,000 lei. For noise reducing to be as high as possible it is necessary to apply all 3 action plans so as the number of inhabitants who are affected by the levels of noise over the limit values to be as small as possible (ideally 0). Combined implementation of those 3 action plans is also the recommended variant by the developer of this study in order to increase the effects of noise reducing in the city.

In those areas where even after the implementation of measures of reducing for Ln > 50 dB we propose passive protection. It would be indicated to start a program to „change the windows” first for the buildings which are placed along the rails (including rails for trams) for which even after the measures implementation the level of noise Ln > 50 dB. Industry source of noise Currently IPPC industrial units don’t cause the exceeding of noise limit value in the administrative area of the city. Following there are listed different measures which can be applied to reduce the noise due to source of industry. Action plans to reduce levels of noise in Iaşi City 43 The most effective tool to prevent noise problems is good planning. It is a long-term instrument that will not solve the immediate problems, but based on strategic noise maps, urban plans can be adjusted to ensure that no new buildings are built in areas with a high impact of noise and and to ensure that no new enterprises/business which generate noise are placed close to quiet or residential areas. The planning process can also be used to improve the environment in the area, in this way ensuring that long-term use of land is changed. It can be decided for example that a residential area with high impact of noise should change gradually in an area with a less sensitive character, for example small offices and workshops. When building new roads, railways, airports and industrial units it has to comply with the legislation in force so that new investments should be subject to a careful analysis of the environmental impact. In strategical mapping there were considered only the industries included in the IPPC directive. Normally, these industries have an environment authorization which includes the conditions regarding the emission of noise outside. This include information regarding to main important source of noise in industrial unit. The noise reducing can be divided in three types: reduce noise at source mitigate the path of propagation measures around the receiver Reduce noise at source Old and noisy machinery could be replaced with machines / equipment with low noise. It’s needed that this fact to be at least part of long-term strategy. Inland transport and other outdoors noisy activities should be minimized, especially at night. Existing machines can be made quieter by closing them inside different enclosures, silencers, etc.. Consideration should be given to reduce noisy activities during the night. Improved mitigation on path of propagation Phonic barriers or ground thresholds can be use in some cases to reduce the noise. The barriers should be placed either near the machine or near the houses. The bariers placed in the area of industrial unit is several times usefull, because several sources of noise can be found with a height above the ground and the distance between Action plans to reduce levels of noise in Iaşi City 44 most sources of noise and barriers may be too high. Measures around the receiver The level of noise inside the houses can be improved by isolation of the facades and possibly by (re)construction of the roof. The most critical components are normally the windows. It can be installed new windows with soundproof glass. To ensure good results it is very important to carefully examine the building and to identify and prioritize the the paths of noise transmission. The procedure consists in calculation of the noise inside the building in different rooms. The method of calculation is described by ISO 12354 standard „noise transmission through the facades of buildings”. Through this method it can be determined the contribution to levels of internal noise through different component of the building. The total level is calculated by summing of the contributions. Industrial noise may contain high energy at low frequencies. Insulation against low frequencies is complicated and expensive. Air traffic The most effective tool to prevent noise problems is good planning. It is a long-term instrument that will not solve the immediate problems, but based on strategic noise maps, urban plans can be adjusted to ensure that no new buildings are built in areas with a high impact of noise and and to ensure that no new enterprises/business which generate noise are placed close to quiet or residential areas. The planning process can also be used to improve the environment in the area, in this way ensuring that long-term use of land is changed. It can be decided for example that a residential area with high impact of noise should change gradually in an area with a less sensitive character, for example small offices and workshops. When building new roads, railways, airports and industrial units it has to comply with the legislation in force so that new investments should be subject to a careful analysis of the environmental impact. Action plans to reduce levels of noise in Iaşi City 45 In recent decades, due to globalization, there was been an increased interest in air transport. In the past, travels by aircraft represented a luxury, but currently they become accessible to a wider and wider public. Hundreds of people use the plane to arrive from Iasi in other places in the world, quickly and conveniently. Obviously very few are thinking about the noise made by aircrafts. It should be noted that air traffic, like other modes of transport, is a source of noise. Noise reduction measures may be taken only by compliance with the rules regarding airline flight safety and technical capacities. In the last years, in terms of environmental protection, the requirements for aircraft became more harsh also because of the need to reduce noise. In the last 30 years the aircraft noise emission decreased by approx. 10 to 15 dB. But although aircraft noise emission has decreased significantly, there was an increasing in number of complaints against noise from air traffic. Characteristic for air traffic noise is that after a longer or shorter period of silence, there is a significant increase of noise. These high values trigger negative subjective assessments against noise of air traffic. Currently, for noise regulation in Europe it is used the equivalent noise level. Obviously, after the implementation of measures to reduce noise, particular noise problems will remain but the average value of noise level and the people affected will decrease significantly. Air traffic noise consists of the following parts: the noise of the engines, aerodynamic noise, engine noise tests and ground maneuvers. On the base of noise maps there was found that engine tests and the ground maneuvers don’t produce noises that exceed the limits. The factors that influence the noises over the limit value are: air traffic value, the division or air traffic after time, the characteristics of the engines/aircrafts, location of flight paths. Effective noise reduction can be achieved by use in the same time of measures. For Iasi International Airport it can be taken measures in the following domains: Action plans to reduce levels of noise in Iaşi City 46 a) Reduce the emission of noise of aircrafts which use the airport There are available several measures (for example fines) through which the airport can impose to airlines companies that at night or in quiet hours to use more silent aircrafts. b) Optimize the traffic in terms of noise for night or quiet hours After the reducing of noise emission of aircrafts, it is very important to reduce noise emission for all the flights in the evening and the night. Then the disturbing effect is enhanced. To reduce the noise it arises the possibility to optimize the time of departure and arrival of certain types of aircraft. Based on a mathematical formula, every aircraft using the airport, depending on the emission of noise, got a share. Based on these shares during the quiet hours and over night can be limited the aircraft movements so that more silent is an aircraft, the more of this type aircrafts the airport can get in these periods of time. Exceedings of indicated rates are possible in cases of emergency. c) The change of flight routes The transfer of flight routes over the roads with heavy traffic or over low populated areas. When transferring flight route over a road with heavy traffic, noise from road traffic will cover the noise of air traffic. In case of transfer over a low populated area, it must be remembered that this transfer will have an adverse effect on the area, which was until then was not affected by flight noise. Please note that changing flight routes can be made only in those areas where on the base of strategic noise maps it was found that there is no conflict. In the immediate vicinity of the airport, where the number of those affected is large, this solution does not lead to any decrease in the level of noise. Since any changes in flight routes can not be made solely on the basis of noise protection, these changes in flight routes are the responsibility of professionals in air safety and flights directing. d) Passive acoustic protection Passive protection arrangement in protected buildings, primarily in areas with exceedings of limit values. e) Prepare a monitoring system Preparing a monitoring system around the airport with several fixed and mobile points of measurement. Obviously this measure doesn’t lead to decrease of noise due to air traffic Action plans to reduce levels of noise in Iaşi City 47 but, through their use can immediately be investigated the legitimacy of people’s complaints and if these complaints are justified, proper measures can be taken. Accurate and fast verification of complaints will lead to the decrease of unfounded complaints. f) Systematization In systematization, should be considered that areas with different uses, to be affected as little as possible by noise of other areas. In areas near the airport, where it’s following to build should be taken into account also the noise of airport which is to be built should be considered and airport noise. This measure will not decrease the noise from the airport, but will prevent the increasing of number of those affected by noise in the future. The proposed action plans for Iaşi International Airport: Action Plan 1 (PA1) Change the flight route for departures during the night (between 23 pm and 7 am) by aircrafts so as the departures to be made on North direction. By applying this measure it will be significantly reduced the number of inhabitants affected by values of noise over the limits permitted by legislation. The number of persons affected by the levels of noise over the limit values, after the implementation of PA1 – Lden dB band 55-60 60-65 65-70 70-75 > 75 No. of persons* 1 0 0 0 0 * The number of persons affected by noise is expressed in hundreds. The number of persons affected by the levels of noise over the limit values, after the implementation of PA1 - Ln dB band 45-50 50-55 55-60 60-65 65-70 No. of persons* 4 1 0 0 0 * The number of persons affected by noise is expressed in hundreds. > 70 0 The difference between the initial total number of persons exposed to noise produced by air traffic (2011) and the total number of exposed persons, after the combined application of PA1 – Lden dB band 55-60 60-65 65-70 70-75 > 75 No. of persons* 16 4 0 0 0 * The number of persons affected by noise is expressed in hundreds. Action plans to reduce levels of noise in Iaşi City 48 The difference between the initial total number of persons exposed to noise produced by air traffic and the total number of exposed persons, after the combined application of PA1 - Ln dB band 45-50 50-55 55-60 60-65 65-70 No. of persons* 12 12 2 0 0 * The number of persons affected by noise is expressed in hundreds. > 70 0 Assessment The above results show that through proposed measures it won’t be persons affected by noise over the limits stipulated by legislation for Lden. For areas where even after the implementation of the measures to reduce the noise for Ln > 50 dB we propose passive protection. It should be indicated to start a program for „change the windows”, first for the buildings situated along the streets for which even after the implementation of measures to reduce the level of noise Ln > 50 dB. Establish quiet areas The quiet area of the city is that area established by the City Hall, where for all the sources of the noise there are accomplished the conditions that the level of noise to be lower than 55 dB. (We mentioned that based on the rules, the minimal surface of quiet area should be minimum 4,5 ha). Ensuring the level of low noise of the areas for which can be said at the moment that they are quiet (Lden < 55 dB) can be maintained through systematic accomplishment of the measures listed in action plan. Quiet areas in Iaşi Only in areas closed for traffic we can talk about a situation more favorable for the noise. Currently there are stated the following quiet areas: Botanical Garden The following areas could be stated as quiet areas: Copou Park Exposition Park Şorogari Forest Ţicău Forest Ciric Forect Valea Ursului Forest Cetăţuia Forest Breazu Forest Action plans to reduce levels of noise in Iaşi City 49 Fig. 4 – Quiet areas in Iaşi Delimitation of quiet areas The quiet area of the city is that area which is delimited by City Hall, where for all sources of noise there are accomplished the most harsh conditions regarding the limits of level of noise. Quiet environment is that non-built area, delimited by City Hall, where it doesn’t exist industrial noise or noises generated by leisure activities or traffic. The aim of delimitation of quiet areas is that to preserve the “silence” of the area, in other words, not even on long term the noise of the area not to exceed the current value and inside the area not to be placed sources of noise. Based on strategis maps of noise, the commission formed at Iaşi Environment Protection Agency together with City hall representative decided that the following areas can fi considered as quiet areas: Botanical Garden Copou Park Exposition Park Action plans to reduce levels of noise in Iaşi City 50 Şorogari Forest Ţicău Forest Ciric Forest Valea Ursului Forest Cetăţuia Forest Breazu Forest A part of these are located on spaces delimited by main streets, so on their border the level of noise is quite high, and only inside them this decreases to 55-65 dB. The spaces near the main streets/roads can be protected by soundproof panels, inside the park can be delimited a quiet area. Although it was proposed through the previous action plan as quiet area, Ciric recreational area can not be declared so because the process of modernization, rehabilitation and reorganization of this area will be complete only this year (2014). The designation of quiet area can be made as follows: The City Hall has to designate the quiet areas of the city. These quiet area should be integrated in Urban Plan of the city. On the regulatory plan of the area should be indicated the “quiet areas of the city”. These areas are essentially those parts of recreational areas, sanitary areas, protected areas, on which is wished to maintain the current situation, favorable for noise, on long term. In these areas can not be placed sources of noise, not even in the situation in which protection measures are ensured. The above requirement governs the overall noise of all sources of noise (road traffic, railways, industrial etc.). We mention that this value is extremely severe, so with this condition can be prevented the noisy becoming of the areas. The designation of the areas should be represented also graphically (on map) and has to be indicated on the regulatory plan of the area. Measures for buffer areas a) Şorogari Forest: - area = 87,13 ha - delimited by = CA Rosetti Blvd. to East, şos. Ştefan cel Mare in North-West, Ţicău Forest to South.

Measures to maintain a quiet area the Botanical Garden implement all the envisaged measures for road traffic source, to decrease the volume of traffic on the arteries which delimit the area; forbid the placement of other sources of noise. Of the list of porposed quiet areas, Exposition Park and Copou Park can be declared as quiet areas in a first phase, on medium and short term. We recommend that other previous mentioned areas, which accomplish the requirements of quiet areas to be declared so, step by step as part of long term strategy. 2.10. Long term strategies Action Plan for the next five years should be completed with a longer-term strategy which to illustrate the long-term vision of noise reducing. Often it will be obvious that many of the ideas developed in the preparation of the plan shall be settled better in a longer term. This fact is especially true for noise reducing measures potentially very costly. The most effective tool to prevent long-term problems of noise is good planning. This longterm tool that will not solve the immediate problems, but based on strategic noise maps, urban plans can be adjusted to ensure that no new buildings are built in areas with a high impact of noise and and to ensure that no new enterprises/business which generate noise are placed close to quiet or residential areas. The planning of the actitivies to prevent the noise (attention, NO FOR REDUCING) and to preserve the quiet areas is feasible to be included in long-term strategies. Action plans to reduce levels of noise in Iaşi City 53 According to „Strategy for sustainable social-economic development of Iaşi City – Horizon 2020”, it is envisaged that environmental issues to be integrated to other domains as much as possible. Thus, among the Strategic Objectives of environmental protection in Iaşi City are included: Integration of the environmental regulations in urban development plan. Transforming public services of water, gas, electricity, in efficient organization from the energy point of view. Integrated management of solid waste in Iaşi. Promote activities to inform the public about the long-term effect of pollution. Stimulate and facilitate the rehabilitation of underground drainage and water networks. Part of the proposals which can be found in „Strategy for sustainable social-economic development of Iaşi City – Horizon 2020” regarding the improvement of environmental quality we mention: Urban Mobility Plan. Passengers public transport management which includes among other: - the analysis of the impact of public transport on the environment and air quality; - the renewal of vehicles fleet; - permanent promotion among the residents and visitors of integrated services and charging system. Create green spaces and recreational spaces. Designate as quiet areas the following forests located on administrative land of the city: Şorogari, Ţicău, Ciric, Valea Ursului, Cetăţuia, Breazu. 2.11. Financial information (if available): budgets, evaluation of economic efficiency, cost-benefit assessment Official financial information are not available from Iaşi City Hall (except those presented in tables 2a and 2b). In what follows it will be shown the cost of the measures described in the documentation. It is important to note that the current phase is only an assessment based on professional experience. The exact cost of the works marked with * will be determined only after the execution of the works to reduce the noise. It is important to emphasize that not all the costs will borne by the Municipality, for example for noise generated by rrailway traffic, the costs to reduce the noise are usually borne by SNCFR.

The sensitive point of traffic, especially of road traffic, is the harmful effect on health and who will compensate these damages. Usually the effect of acoustic pollution of traffic is treated less comparative wit the effect of air pollution (NOX). In the literature we find different dates, for example in some works it is estimated that the demaging effect of noise is about half of the effect of air pollution, while in other works is stated that this is a third or even a quarter of the effect of air pollution. The demaging effects of noise pollution on health are: hearing damage; audibility problems; sleep disturbance whose consequences can be blood pressure, increased hearth rate, hearth rhythm disorders and so on; physiological effects, which may be temporary or permanent; mental diseases; negative effects on capacity. Risk groups: people suffering from chronic diseases (e.g.. Hypertension), persons in covalescence, persons dealing with complex cognitive problems, Action plans to reduce levels of noise in Iaşi City 55 blind people, people with hearing diseases, toddlers, babies, embryos, elderly people. The demaging effects on health can fi quantified through: number of days of sick leave, number of days of care in hospitals, number of cases of disability, number of deaths. Undesirable effects will decrease in proportion to the reduction of noise.. b) Other social benefits Among other social benefits we consider only the one related to increasing of the value of affected buildings after the implementation of noise reduction measures. When a high traffic street is built in a residential area it will decrease the value of buildings, which are located along this street. There are many such examples in European cities. In many cases the court ruled the compensation of people affected, with up to 30-40% of the value of property. In this case the situation is just the reverse, for buildings that were executed sound isolation works (change windows, isolation with polystyrene), we can expect an increase of value of property. The effect of road traffic on the value of the property can be determined by hedonic method of calculation. The hedonic method of calculation This method makes a statistical analysis on a large number of data. Beside the price of the property, it takes into account other characteristics as the number of rooms, the accessibility, information regarding the neighbors, environmental variables. Based on these it is designed a statistical model, after that there are included other 7 factors (among them, the noise) in order to identify their effect on the value of the property. Of these 7 factors, after all there were considered only the noise, because the most requests for compensation refer to this aspect. On this model, it was calculated that in case of a increase of road traffic noise with 1 dB, the value of properties will decrease with 0,6 %. In our case, to a reduction with a 1 dB of road traffic noise will have an increase of value of the properties by 0,6 %. Action plans to reduce levels of noise in Iaşi City 56 2.12. Provisions taken in consideration in the assessment of implementation and the results of action plan. The results of plan implementation will be assessed as changes in the number of persons affected by noise will appear. The number of persons affected by noise will be modified when the measures to reduce the noise will be applied and it will be possible to calculate the occurred change in comparison with current situation.
