DYNAMIC ROUTE GUIDANCE SYSTEMS BY A COMBINATION OF INFRASTRUCTURE SUPPORTED AND AUTONOMOUS MODE - EXPERIENCES FROM THE STUTTGART TEST FIELD

In the STORM project, a dynamic route guidance system is currently being installed in Stuttgart. In the outer area, the system runs in the autonomous mode and takes into account RDS/TMC messages. In the inner area, beacons have been installed which transmit the individual optimum routes to equipped vehicles according to the actual traffic situation in the city. Equipped vehicles transmit their individual travel times for the travelled routes. In both modes, time-shortest routes are recommended to the drivers. The actual traffic situation is determined by merging different sources of information like loop detectors, disturbances registered by the police, travel times by equipped vehicles and the parking situation. The system assessment is based on experiences gained in the field test and on simulations. Acceptance, user comfort, and system benefit are surveyed in the field test for a user collective of 4O drivers. In order to evaluate the effects of a higher proportion of equipped vehicles, the strategy is implemented in a simulation model. Simulations are conducted on an extensive data basis for different traffic situations by means of calm traffic morning peak and unusual events. Incidents resulting from a reduction of capacity on a road section are modelled in the network. First results have already been presented.
