摘　　要：为了提高排阵式交叉口在实际应用中的运行效率和稳定性,针对不同的排阵式控制模式,对其车道功能和信号控制协同优化方法进行研究。在分析了3种排阵式交叉口几何设计模式的运行特性和2种排阵式交叉口信号控制策略的控制特点的基础上,综合兼顾排阵式交叉口的运行效率和稳定性,以交叉口延误均值和延误均值半标准差为优化目标,考虑了进出口车道数、主预信号绿灯时长、排序区长度等约束条件,建立了排阵式交叉口车道功能-信号控制协同优化模型,并采用改进的非支配排序遗传算法进行求解。通过2个案例分析,分别针对既有排阵式交叉口的优化提升和常规交叉口采用排阵式控制策略的改善效果进行了分析,验证了模型的准确性和综合效益。研究结果表明:所提出的协同优化模型可在不同排阵式控制模式和交通状态下提升控制方案的运行效率和稳定性。相较于常规设计方案,在交通效益(案例中车均延误和平均排队长度分别降低了19.61%和20.94%)和环境效益(案例中CO产生量和NO_(x)产生量分别降低了10.93%和12.97%)层面均有较为显著的提升。An integrated optimization model for lane function and signal control is proposed to improve the efficiency and stability of tandem intersections.Based on analyses of three types of tandem control modes and two types of signal control strategies,an optimization model framework was established to minimize the combined value of the mean and semi-standard deviation,considering the constraints of the lane number,signal,and length of the sorting area.The proposed model was solved using the improved Nova Scotia-Gambia Association algorithm.Two case studies were used to analyze the accuracy and optimization effect,which considered the mode optimization of a tandem intersection and the control strategy for a conventional intersection.The results show that the established integrated optimization model could improve the efficiency and stability of the control scheme under different tandem control schemes and traffic conditions.Compared to traditional design methods,the traffic benefits(a 19.61%decrease in the average delay and 20.94%decrease in the average queue)and environmental benefits(a 10.93%decrease in CO production and 12.97%decrease in NO_(x)production)at the intersection were significantly improved.
