Multiprocessor architecture for adaptive control of traffic light systems

Abstract

Construction of new highways or expansion of existing highways to meet the ever- increasing highway traffic is a very expensive and time-consuming task. Management of existing highways effectively is considered as a high priority option in Traffic and Highway Engineering. Traffic control by a system of traffic signal lights and variable message signs that can adapt to the changing environment is an essential part of such management scheme. The multiprocessor architecture described in this paper maintains near neighbor connectivity and shares information via these near neighbor interconnections for calculation of optimum traffic plans. The near neighbor connectivity simplifies the expansion of the multiprocessor architecture with city developments.
