Autonomous Agents Controlling Traffic Lights — •Jürgen Mikat, Elmar Brockfeld, and Peter Wagner — Institute of Transport Research, German Aerospace Center (DLR) in der Helmholtz-Gemeinschaft, 12489 Berlin-Adlershof, Germany

In todays’ road networks, traffic management methods are of more and more importance with steadily increasing traffic. Detector values are related to pre-assigned, fixed signal programs or used to adapt the signal phases within a signal phase frame. Drawbacks of these detectors are high installation costs and limitations in data usage. From a single detector information on vehicle speeds or number of vehicles waiting is not available. With the development of information technologies new kinds of detectors allow a more flexible operation of traffic signals by using additional information on traffic flow. This allows in turn the development of concepts of autonomous acting traffic lights reacting on the demand at the intersection or within the approaches. We give examples of autonomous acting traffic lights equipped with simple rule sets optimizing the traffic flow along a road segment and between several neighboured intersections.
