Towards a robust and wide-area traffic signal control for inner-city areas

Thunig, Theresa; Nagel, Kai

This paper examines different signal approaches to control inner-city traffic and compares them with respect to two use cases - an illustrative gridlock scenario and a more complex real-world scenario. Based on the idea of back-pressure, it aims to develop an appropriate signal control method for inner-city traffic that reacts to current traffic and considers route choice, oversaturation, and spillback. For evaluation, the agent-based transport simulation MATSim is used. First positive results are presented. Difficulties that occur while applying the approach to the more complex scenario are analyzed. The outlook discusses suggestions to address these difficulties in the future.
