A phrase difference computation approach for area traffic control system based on period of time
-
摘要: 在区域协调控制的基础上,对低峰期、平峰期和高峰期不同方案的相位差计算进行研究.采用将高峰期分为子区间,并根据实时采集的车流量动态进行相位差计算的策略,改进了高峰期的传统相位差计算方法.仿真结果表明,该相位差计算方法实用有效,可应用于区域交通控制中不同情况的相位差计算.Abstract: The calculation method of phase difference for three schemes of low traffic flow,normal traffic flow and high traffic flow was studied based on regional coordination control.The tradition phase difference calculation method was improved using the strategy which divided high traffic flow into subinterval and phase difference calculation was carried out according to acquisition of the number of cars.The simulation results showed that this method was effective,it can be used for phase difference calculation at different conditions in regional traffic control.
