The implementation of state-of-the-art traffic control systems requires methods for
detecting the current traffic state. A high quality traffic state recognition is a prerequisite for providing reliable traveller information, for forecasting the future state of the
transport network and, in combination with a model, for evaluating and implementing
control strategies. The primary data sources for traffic state recognition are roadside
detectors (e.g. loop detector, overhead detector) which can measure occupancy
rates, volumes and speeds for one lane of a road. Mobile detectors moving along
with the traffic flow complement the stationary data by delivering time-space trajectories of single travellers. Usually mobile detectors are integrated in the navigation system of cars which broadcast floating car data (FCD) to a control centre. Main disadvantages of FCD are the low rate of equipped vehicles and the still relatively high
communication costs. As an alternative, observation of mobile phones can provide
floating phone data (FPD or Net-FCD) for a large number of travellers in the network.
The research project Do-iT, funded by the German Federal Ministry of Economics
and Technology, aims at exploiting FPD in a pilot area in Southern Germany. The
research project which is scheduled to run until 2009 intends to prove that FPD contribute to the following objectives:
• Provision of traffic state information for motorways and the secondary road network.
• Improving methods for detection and forecast of the traffic state by applying origindestination matrices derived from FPD.
• Continuously monitoring the service quality (travel times) and the travel behaviour
(travel demand, route choice) in the network for planning purposes and for evaluating telematic control strategies.
