摘　　要：针对协调路径数目增加后绿波带宽变窄问题,本文提出一种考虑路径关系的多路径协调控制优化模型。分析路径的相关关系,构建上下行分区和路径分解模型;引入子区划分参数,改进经典多路径模型,构建子区内部协调约束;分析路径在相邻子区之间的衔接特征,构建子区间连接性约束条件;综合考虑子路径长度和流量构建权重系数,以各子路径绿波带宽加权和最大为优化目标,建立多路径协调控制优化模型。为验证模型的有效性,选取南京市典型干道为研究对象开展案例分析。实验结果表明,本文提出的模型可以有效增大绿波带宽,相较于对比模型,加权绿波带宽和提高49.44%。利用VISSIM验证了方案的应用效果,仿真结果表明,本文模型方案可以获得更高的通行效益。相较于对比方案,关键路径车均延误和车均停车次数明显降低,干道车均延误和车均停车次数分别降低了20%和27%,车辆平均速度提高了17%。本文模型可为城市道路干线协调控制提供理论基础。In response to the issue of reduced green bandwidth after an increase in coordinated path numbers,this paper proposes a multi-path coordinated control optimization model considering path relationships.The relatedness of paths is analyzed,and models for partition of outbound and inbound and decomposing paths are constructed.Subgroup division parameters are introduced to improve the classical multi-path model,and intra-subgroup coordination constraints are established.The connection characteristics of paths between adjacent subgroups are analyzed,and inter-subgroup connectivity constraint conditions are defined.The weight coefficients considering the length and traffic of sub-paths are also incorporated in the model.The optimization objective is to maximize the weighted sum of green bandwidths of each subgroup.A case study is conducted on a typical main road in Nanjing City to validate the effectiveness of the model.The results show that the proposed model effectively increases the green band width,with a weighted green band width improvement of 49.44%compared to the benchmark.The application effect of the scheme is verified using VISSIM software,and the simulation results demonstrate that the proposed model scheme achieve better performance than the traditional methods.The arterial average delay is reduced by 20%and average number of stops is reduced by 27%on critical paths,while the average vehicle speed increased by 17%.The proposed model provides a theoretical basis for the coordination control of urban arterial.
