Real-Time Traffic Conditions with SUMO for ITS Austria West

Abstract

ITS Austria West is a long-term project, funded by the Austrian government, to create a platform for providing real-time traffic data and prognoses. The calculation of the traffic situation is based on the open source package SUMO (Simulation of Urban MObility). One innovation in this project is the scenario builder, a module which maintains the origin/destination matrix and aggregates data from various sources, like traffic counters and floating car data. The simulation model is continuously calibrated in order to provide an accurate view of the traffic situation in the whole street network. The calculated level-of-service information is visualized and exported to other intelligent transport systems. Due to the complexity of the model (streets, vehicles and real-time data), the simulation’s performance is unsatisfactory. A possible improvement is the parallelization of SUMO.
