摘　　要：针对现有区域绿波协调控制模型主要面向单周期控制方式的局限,提出了一种适于不等双周期控制需求的区域绿波协调控制模型。该模型给出了区域公共信号周期取值范围计算及双周期交叉口确定方法;根据双周期控制方式的主要特点,分别针对单周期与双周期交叉口建立了相位起始时刻、相位执行时间、相位相序、协调车流的起始时刻与通行时间的约束条件;利用投影计算方法,以各股协调车流的绿波带宽占比与交通流量加权之和最大作为优化目标,建立了区域绿波协调控制目标函数。以深圳市福田区部分实际路网作为案例,分别从单交叉口、协调路径链和区域整体的角度,以平均延误时间和平均停车次数作为评价指标,对比了现状方案、Synchro优化方案与所提出模型方案的控制效果。结果表明:所提出的双周期控制模型方案能够有效降低交叉口及整个区域的平均延误时间,与Synchro双周期控制方案相比,区域车辆平均延误时间和平均停车次数分别减少了13.94%和9.71%;同时该模型也能够显著提升区域内协调路径链的整体控制效果,与Synchro双周期控制方案相比,协调路径链车辆平均延误时间和平均停车次数分别减少了66.41%和55.73%。可见,该模型能够实现协调区域内单周期与双周期交叉口的协调优化,适用于协调区域内存在路段人行横道、主路与支路相交或干道与支路相交的复杂交通场景,在控制区域内,特别是协调路径链上取得了较好的协调控制效果。To overcome the limitations of existing regional green wave coordinated control models,which are primarily oriented toward the single-cycle control mode,a regional green wave coordinated control model suitable for unequal double-cycle control demand has been proposed.This model provides a calculation for the regional common signal cycle range and a method for determining double-cycle intersections.Based on the main characteristics of the double-cycle control mode,the constraints for phase initial point,phase execution time,phase sequence,as well as initial point and passage time of the coordinated traffic flow were established for both single-and double-cycle intersections.The objective function of the regional green wave coordinated control,which maximizes the weighted sum of the green wave proportions for each coordinated traffic flow and its volume,was established using the projection calculation method.The proposed model was applied to a partial real-world network in the Futian District,Shenzhen City,Guangdong Province,China.To compare the control effects of the status quo,Synchro,and the proposed model,two evaluation indicators-average delay time and average number of stops-were chosen to evaluate them from the perspectives of intersection,coordination path chain,and the entire network,respectively.The simulation results indicate that the proposed model effectively reduces the average delay time at intersections and in the entire network.This scheme reduces the regional average delay time and the average number of stops by 13.94%and 9.71%compared to the Synchro scheme in double-cycle control mode,respectively.Additionally,the proposed model improves the overall control effect of the coordination path chain in the region,reducing the coordination path chain average delay time and the average number of stops by 66.41%and 55.73%compared to the Synchro scheme in double-cycle control mode,respectively.Thus,the proposed model can achieve coordinated optimization for both single-and double-cycle intersections in th
