摘　　要：为克服车辆到达的随机性和车辆速度波动性给干线协调控制带来的不利影响,降低相交道路右转汇入车辆对干线直行车辆的影响,提出以绿波带宽最大为目标的干线协调与速度引导集成优化模型。首先在Maxband模型中引入速度引导来调节干线直行车辆到达交叉口的时刻,提升绿波时段内干线直行车辆的通行效率;然后确定可用于相交道路右转汇入车辆的绿灯时间,并给出右转汇入车辆的速度方程;最后采用Vissim和Matlab进行仿真实验,对比所建模型与Maxband模型的仿真结果。结果表明,初始实验条件下干道直行车辆的平均延误降低17.4%,平均排队长度减少36.8%,而相交道路右转汇入车辆的平均延误和平均排队长度没有增加,说明所建模型可提升干线协调控制效率。通过灵敏度分析发现,所建模型适用于右转汇入车流量小于550pcu/h的情况,且模型的效果与右转汇入车辆的可通行时间有关,随着右转汇入车辆的增多,增加可通行时间可提升模型效果。In order to overcome the negative effects of vehicle arrival randomness and vehicle speed fluc-tuation on arterial coordination control,as well as to reduce the impact of right-turning merging vehicles on arterial straight traffic flow,an integrated optimization model of arterial coordination and speed guidance was proposed with the objective of maximizing the green wave bandwidth.Firstly,based on the Maxband model,speed guidance was introduced to regulate the arrival moment of arterial straight traffic at the intersection to improve the efficiency of arterial straight traffic during the green wave period.Second-ly,the green traffic light time that could be used for right-turning merging vehicles on intersecting roads was determined and the speed equation for right-turning merging vehicles was given.Finally,simulation experiments were conducted using Vissim and Matlab,and the simulation results of the model constructed in this paper were compared with those of the Maxband model.The simulation re-sults showed that the average delay of the arterial straight was reduced by 17.4%and the average queue length was reduced by 36.8%under the initial experimental condition,while the average delay and average queue length of the right-turning merging vehicles on the intersecting roads didn′t in-crease,therefore the model constructed in this paper could improve the efficiency of arterial coordina-tion control.Through sensitivity analysis,it was found that the model constructed in this paper was ap-plicable when the right-turning merging traffic flow was less than 550 pcu/h.Moreover,the effect of the constructed model was related to the passable time of right-turning merging vehicles,and with the in-crease of right-turning merging vehicles,the increase of passable time could improve the model effect.
