摘要

The coordinated control of urban trunk roads played an important role in improving the capacity of urban network. In this paper, the optimization model of vehicle saturation under the condition of signal coordination control was put forward. Through the Vissim simulation analysis of the intersection of one road, the optimal allocation of signal coordination scheme was carried out. The results showed that the main traffic capacity had been significantly improved after optimization with obvious optimization effect, which had a very important reference for the improvement of urban traffic in our country.
