可变车道行驶方向的动态控制方法研究

Study on dynamic traffic control for reversible lanes

针对大城市道路双向交通需求不均衡的潮汐交通问题,提出一种根据双向交通运行状态动态控制可变车道行驶方向的交通控制方法.利用可变车道路段双向饱和度分析道路交通运行状态,以此划分为5种交通状态,建立各种交通状态下对应的车道行驶方向优化模型,并使用枚举法对模型求解,最后应用微观仿真软件进行案例分析.结果表明:与传统的定时控制模式相比,本文提出的动态控制方法能够更好地减少潮汐路段的车辆平均延误和提高车辆通行效率,有效缓解潮汐交通需求条件下的道路交通拥堵现状.

This paper proposes a dynamic traffic control method for reversible lanes according to the traffic flow state of both directions of the road to ease the problems of traffic demand imbalance of both side of road section, which is called tide traffic problems. Saturation degree is used to analyze the traffic state of road section that has reversible lanes. Five traffic situations are proposed and optimization model of each traffic situation is developed. Enumeration method is used to solve the proposed optimization models. Finally, a case study using micro-simulation shows that the proposed dynamic traffic control method of reversible lanes can reduce the average delay and improve the traffic efficiency of road sections that contain reversible lanes.
