Real-time Traffic Signal Control Model And Algorithms Research

The traffic problem is becoming a world-class problem, it will influence the developing of city economy and people's life. In the same time, it also attracts many scientists working on it. As a across subject, concerning other subjects or technologies is very important.This paper is about the intelligence transportation controlling system prototype. And it gives a new prototype. There is a very particular introduction about the relationship among the modules, algorithms and layers. The 3-layer module consists of intersection controlling layer, main road controlling layer, and space distributed layer. During the introduction, it makes it clear, that the module is correct and effective. It analyses algorithms and calculating model in the system very clearly. And prove that loose-coupling layers model is appropriate for extending, such as changing detectors, etc. After that, for implementing this model, it gives the solution in details for real problems. And then, it designs the system software, develop the model, and coding. Finally, this paper gives the standard about evaluating the traffic controlling system, and using simulation software technology to prove the correctness of the model. It proves that this model could be used in optimizing urban traffic flows. The model can be better for some reasons, this paper point them out.
