Oktober 2013 | PHK Steffen Laskosky 2 A task for the police = the accident report Reasons for the accident report and analysis: • • • • Removal of dangerous situations or objects caused by the accident Investigation of criminal offences or misdemeanours Statistical analysis of accidents, finding blackspots and identifying contributing factors and eliminate deficits in road infrastructure Providing civil law claims Overall objektive: Avoiding accidents with safer roads! ETC Frankfurt | 1. Oktober 2013 | PHK Steffen Laskosky 3 What exactly does the term roadsafety mean? Thesis I • As opposed to sensations like warm/cold or light/dark, road safety is not tangible, As - • it is the number of accidents, the following investigations of the site and the traffic situation, which allows us to realize the safety of a road. ETC Frankfurt | 1. Oktober 2013 | PHK Steffen Laskosky 4 Accidental accidents? Thesis II • road accidents do not happen “by accident”. As – • it cannot be solely the fault of the drivers, if a large number of different road users keep making the same mistake at the same site, • in this case something is wrong with the site respectively road itself. .

Oktober 2013 | PHK Steffen Laskosky 14 Data relating to the site of the accident Daten zum Unfallort • Area (urban, non urban) Ortslage (iO, aO) • Driving direction (ascending, desdending) Fahrtrichtung (aufsteigend, absteigend) • Characteristics of locatation(crossing、indention、slope、turn) Charakteristik (Kreuzung, Einmündung, Gefälle, Kurve…) • Specific features ( pedestrian crossing, bus stop) Besonderheiten (Fußgängerüberweg, Haltestelle…) • Road conditions ( dry, wet, moist, icy or slippery) Straßenzustand (trocken, nass/feucht, winterglatt…) • Light conditions(daylight、darkness、twilight) Lichtverhältnisse (Tageslicht, Dunkelheit, Dämmerung) • Localiation of the accident ( kilometres, geographical information) Genauer Unfallort (Km-Angaben, geographische Info.) ETC Frankfurt | 1. Oktober 2013 | PHK Steffen Laskosky 15 Data relating to the site of the accident This data is neccessary for the accident investigation for the following reasons: • Identification of similarities refering to the location Feststellung von Gemeinsamkeiten an der Örtlichkeit • Contributiing factors Begünstigende Unfallumstände ETC Frankfurt | 1.

Oktober 2013 | PHK Steffen Laskosky 20 Personal data and vehicle data Statistics relating to personal data: : • age, sex, degree of injury • vehicle used ( passenger car, truck, motorbike, bicycle... • cause of theaccident (alcohol, right of way, speed...) • date of driving license General statistics regarding the vehicle: : • license plate, amount of damage, insurance data • number of passengers ETC Frankfurt | 1. Oktober 2013 | PHK Steffen Laskosky 21 Problems with the compilation of data • time pressure – leads to a quick, superficial and possibly incorrect data input • lack of knowledge concerning accident statistics – prompts people to underestimate certain statistical determination and distinction • lack of knowledge concerning the needs for accident investigation – results in inadequate description of the accident site • lack of knowledge concerning aggregation of accident data results in incorrect lacalization -> the only person who was on site during the accident can truly localize it. ETC Frankfurt | 1. Oktober 2013 | PHK Steffen Laskosky 22 Situation description by type of accident • unsuitable = the kind of accident – just 10 different kinds to chose from, but few are fully applicable • unsuitable = the category of the accident – Consequences of accidents are relatively coincidental and becomíng less and less severe due to improvement in emergency services and the safety features of the vehicles themselves. • suitable = the type of accident – this classification describes the situation before the accident occurred, i.e. the traffic situation and interaction of road users, which is actually based on rules, laws and regulations.
