摘　　要：针对具有混合交通流特征的行人二次过街交叉口,考虑不同信号相序对交叉口交通参与者的影响,选取信号总损失时间、机动车、非机动车和行人平均信控延误最小作为信号相序的优化目标,建立行人二次过街交叉口信号相序多目标优化模型,并给出了计算方法。最后通过实际交叉口案例进行验证,得到考虑交叉口综合交通效益的最优相序,与现行交叉口相序方案相比,损失时间减少1.86%,机动车延误减少1.43%,行人延误减少10.43%。The paper presents a multi-objective optimization model and its solution algorithm for optimal signal phase sequence at pedestrian two-stage crossing intersections with mixed traffic flow characteristics.The signal sequence optimization objectives are the minimum total signal loss time,the minimum average motor vehicle delay,the minimum average non-motor vehicle delay and the minimum average pedestrian delay.A case study is given and the optimal signal phase sequence considering the comprehensive traffic benefits is obtained by using proposed model.Comparing with original phase sequence schemes,the total loss time,average motor vehicle delay,and average pedestrian delay are reduced by 1.86%,1.43%and 10.43%,respectively.
