【摘要】：针对城市交通中日益凸显的潮汐现象,研究合理的潮汐车道配置和优化策略;为了充分利用交叉口时空资源,解决直行方向交通流的不均衡现象及大量左转车辆排队等待的问题,定量分析干线交通流分布不均衡系数及转向不均衡系数,定义协同系数,协同设置潮汐车道与变向车道,并依据干线交通流特性提出半周期绿波协同优化策略,减少因交叉口流量小造成的信号时间的浪费。优化结果表明,潮汐车道与变向车道协同绿波控制的方案有效地缓解了交通拥堵,缩短了停车延误,并且行驶车速平均提高10%。
[Abstract]:Aiming at the increasingly prominent tidal phenomenon in urban traffic, reasonable tidal lane allocation and optimization strategy are studied. In order to make full use of intersections' space-time resources to solve the problem of traffic flow unbalance in direct direction and a large number of left-turn vehicles waiting in queue, quantitative analysis of the unbalance coefficient of traffic flow distribution and the unbalance coefficient of steering is carried out. The coordination coefficient is defined, the tidal lane and the directional lane are set up in coordination, and the semi-periodic green wave cooperative optimization strategy is proposed according to the traffic flow characteristics of the trunk line. The optimization results show that the coordinated green wave control scheme of tidal lane and directional lane can effectively alleviate traffic congestion and shorten parking delay. And the average speed of driving increased by 10.
