Microscopic real-time simulation of Dresden using data from the traffic management system VAMOS

In the city of Dresden the VAMOS traffic management system is developed to collect all available traffic-related data from numerous detectors and to process them for monitoring and decision making. In most cases aggregated traffic data is used to define traffic management interventions and strategies. In some cases, especially for choosing the strategy for the next time period, it is useful to reflect first the current traffic situation, in order to examine the effects of different strategies. This is done by the microscopic traffic simulation software SUMO, which has a real-time I/O data interface. This means that an interaction during the simulation is possible, importing current detection data and traffic signal states from the field now, in order to obtain effects on e.g. delays, tailbacks, emissions and noise just a moment later. Based on these results an advice about which strategy is most efficient can be given. In this paper the system’s setup is described, supplemented by two first examples of its use.
