Simulation of modern Traffic Lights Control Systems using the open source Traffic Simulation SUMO

Abstract

Within the project “OIS” (optical information systems) new traffic control mechanisms had to be invented and tested. One of the most important topics was to optimize the flow over a junction using information from the OIS sensors which can not be measured using normal sensors such as induct loops. For this purpose, an “agentbased” traffic lights logic algorithm was used, which uses the length of a jam in front of a traffic light as input. As we had no possibility to test the traffic lights control within the reality, the improvement of the flow throughput of such junctions was shown using the open source traffic Simulation “SUMO” (Simulation of Urban MObility) [1, 2]. This publication describes the algorithm itself and how it was embedded within the simulation. Furthermore, the simulation results are given.
