Towards a Traffic Telematics Testbed at TUB — •Gunnar Flötteröd and Kai Nagel — Transport Systems Planning and Transport Telematics Group, Sekr. SG 12, Salzufer 17-19, D-10587 Berlin

We present a microsimulation based traffic telematics testbed for integrative evaluation of telematics devices and strategies. As a synthetic reality, we apply the SUMO traffic simulator which microscopically represents traffic dynamics, driver’s long ranging route choice and spontateous en route replanning; we also prepare to extend SUMO by a module for activity based demand generation. On the traffic telematics side, we currently focus on two aspects: Traffic Monitoring/Prediction and Traffic Control. The former is based on a macroscopic model which we adjust by means of mathematical programming and evaluate by feeding it with synthetic measurements from our SUMO testbed. The latter serves as an extension to SUMO itself and allows for the evaluation of different (mainly agent based) control strategies. To keep the entire system expandable, we systematically integrate all aforementioned subsystems into a general traffic telematics control loop, strongly focussing on real world applications and effortless expandability.
