The invention relates to a lane distribution method for a single-point signalized intersection. The method comprises the following steps: S1, under a determined traffic demand, considering two kinds of traffic objects, namely motor vehicles and pedestrians, constructing a lane-based binary mixed integer nonlinear programming improved model by taking maximization of intersection traffic capacity asa target, and solving and obtaining an optimal lane allocation and signal timing scheme; and S2, considering the fluctuation of the traffic demand, establishing a two-stage random model based on thetraffic demand according to the lane distribution scheme obtained in the step S1, and solving and obtaining the lane distribution scheme with optimal robustness. Compared with the prior art, the method has the advantages that the lane distribution scheme with the optimal robustness is obtained, different traffic requirements can be met, pedestrian safety is considered, the traffic capacity of theintersection is greatly improved, and traffic jam is effectively relieved.

    本发明涉及一种单点信号交叉口的车道分配方法,包括:S1、在确定的交通需求下,考虑机动车和行人两类交通对象,以最大化交叉口通行能力为目标,构建基于车道的二元混合整数非线性规划改进模型,求解得到最优车道分配和信号配时方案;S2、考虑交通需求的波动性,根据S1得到的车道分配方案,建立基于交通需求的两阶段随机模型,求解得到鲁棒性最优的车道分配方案。与现有技术相比,本发明得到鲁棒性最优的车道分配方案,能适应不同的交通需求,且考虑了行人安全,大大提升了交叉口的通行能力,有效缓解交通拥堵。
