平 行 流 交 叉 口 车 道 控 制 与 信 号 配 时 组 合 优 化

A combined optimization method for lane control and signal timing was proposed in order to enhance the flexibility of parallel flow intersections in practical application. Sixteen configurations including one-way, asymmetric two-way, symmetric two-way, three-way, and four-way settings with directional arrangements were integrated into an optimization model, and phase sequences were automatically generated by modifying the traffic conflict matrix. A mixed integer linear programming model was developed to optimize the intersection setting selection, lane allocation, and signal timing in combination. Results show that the symmetric two-way, three-way, and four-way settings increase traffic capacity by approximately 20%, 20%, and 50% respectively compared to conventional intersections under various traffic scenarios. The capacities of the one-way and asymmetric two-way settings are close to those of conventional intersections, indicating that one-way and asymmetric two-way settings are not suitable for parallel flow intersections. The four-way setting exhibits the largest increase in capacity, with a maximum improvement of 70.51%. The traffic capacities of symmetric two-way and three-way settings are similar, while the three-way setting performs better in asymmetric traffic scenarios than the symmetric two-way setting.
