Complex Network Traffic Signal Optimized Model and Simulation

In urban road traffic system, an important issue with the expansion of the network, resulting in the increasing complexity of the network, in-depth analysis of complex network operating mechanism is to further optimize and control network traffic and maximize network efficiency is what we are facing, urban traffic network congestion problem is a typical complex network optimization and control problems. In this paper, optimization and model-ing of complex transportation network will transport net-work abstraction for the network nodes and the intersec-tion of the road, the vehicle network communication ab-stract packets, control timing Intersections, namely switching control network nodes , proposed a distributed message mechanism adaptive optimization method based on network traffic and through mathematical modeling and simulation, to verify its validity.
