Kurzfassung
The optimization of traffic signal systems is an important step towards successful traffic
control, since delays in urban road networks depend largely on the signal system's
performance. Due to their adaptivity, traffic-actuated signal controllers are widely used in
traffic systems around the globe. However, their performance largely depends on the choice of
appropriate control parameters. Here, we describe the application of NSGA-II, a multiobjective
evolutionary algorithm, to the optimization of a traffic-actuated controller. Results
show that parameters found by NSGA-II can be superior to those defined by a traffic engineer
with respect to several objectives, including the resulting travel times and the necessary
number of stops.
