Adaptive traffic control systems are used to improve the performance of intersections with highly variable traffic volumes or other conditions. This paper describes a traffic and weather responsive adaptive signal controlsystem developed to enhance an existing intelligent signal control systembased on fuzzy logic. Built on top of a real-time microscopic simulation model, the adaptation is carried out not only by changing the signal timings and control schemes of an isolated intersection but also by adapting the traffic model to fit the current traffic and weather situation. The system has been tested with simulations and the results suggest that improvements in the performance of intersections as well as in safety can be achieved. Finally some further research is suggested.
