This paper presents a cooperative traffic control strategy to increase the capacity of nonrecurrent bottlenecks such as work zones by making full use of the spatial resources upstream of work zones. The upstream area is divided into two zones: the regulation and the merging areas. The basic logic is that a large gap is more efficient in accommodating merging vehicles than several small and scattered gaps with the same total length. In the regulation area, a nonlinear programming model is developed to balance both traffic capacity improvements and safety risks. A two-step solving algorithm is proposed for finding optimal solutions. In the merging area, the sorting algorithm is used to design lane-changing trajectories based on the regulated platoons. A case study is conducted, and the results indicate that the proposed model is able to significantly improve work zone capacity with minor disturbances to the traffic.

一种改善公路工作区通行性能的队列调度算法

本文提出了一种协同交通控制策略,通过充分利用工作区上游的空间资源来提高工作区等非重复性瓶颈的容量。上游区域分为调节区和汇流区两个区域。基本逻辑是,一个大的间隙比几个总长度相同的小而分散的间隙在容纳合并车辆方面更有效率。在监管区域,开发了非线性规划模型来平衡交通容量改进和安全风险。提出了一种两步求解算法来寻找最优解。在合流区,采用排序算法,根据规管排设计换道轨迹。进行了案例研究,
