Research of multi-line optimal simulation model for urban traffic control

In order to alleviate urban traffic congestion and improve road utilization, this paper proposed a new utility multi-line optimal model and time-space-phase evolution(TSPE) method for urban traffic control. And gave a genetic optimization algorithm based on the model. With the simulation system developed to realize multi-line optimization of urban traffic control, obtained satisfactory results. Comparing with data before and after optimization, the urban vehicles on the routes reached the destinations with minimum average number of stops and shorter average delay time. The model would ease city traffic and improve the urban road traffic capacity with the minimum price and costs.
