Modeling of Real-Time Signal Timing for a Single Intersection in Urban Traffic Networks

This paper develops a real-time signal timing model which is to be integrated into a single intersection in urban area, to some extent, solving the problem of traffic congestion. First, we analyze the current situation of the traffic flow by using release matrix, and then put forward the basic models to minimize total delay time of vehicles at the intersection. Integrated with the Webster split optimal model, the optimal real-time signal timing model (non-fixed cycle and non-fixed split) is built. Through simulation, the preliminary results, which are compared with conventional model, manifest the promising properties of proposed model.
