摘要
提出一种新的干路协调相位差优化方法,采用空间与时间的转化思路,通过对相位差作前移处理,使得停车线位置相对提前,而使车辆匀速通过,减少停车延误,以改善拥堵状况,建立了Vissim仿真模型,仿真结果表明:被研究的两股车流的平均旅行时间分别降低了7.5%与8.1%,平均延误降低16.8%与26.8%,有效改善了拥堵情况。
This paper proposes a new optimization method for the phase difference of trunk roads.Adopting the idea of advancing the position of the parking line in the space dimension and moving the phase difference forward in the time di- mension allows the vehicle to pass through at a constant speed,reducing parking delays and improving congestion situation, and using Vissim software for simulation demonstration.The simulation results show that the average travel time of the two researched trains is reduced by 7.5% and 8.1% respectively,and the average delay is reduced by 16.8% and 26.8%,which effectively improved the congestion and improved the road service level.
