摘要由于公交网络单层规划系统选线复杂,无法平衡路段流量向量,为此根据城市公交网络特点,提出基于数字模型的城市公交网络双层规划系统设计。根据公交骨架线网双层结构,连接公交枢纽及周边多个公交客流需求点,填补公交盲区,设置由点织网、由网定纽、出纽补线的连接结构。建立公交网络双层数字模型,构造公交客流强吸引点集合,利用客流要素,确定公交客流强吸引点集合和可行线路集合,形成点可行路线集,平衡路段流量。通过实际数据统计出一个接近最优解的初始可行解,再进行收敛性验证,得到最优解。由实验结果可知,该系统最佳收敛值为30,能够确定最优路径,为城市公交网络规划提供有力的理论支持。 Due to the complexity of route selection in the single-layer planning system of public transport network,it is impossible to balance the road flow vector. Therefore,an urban public transport network double-layer planning system based on digital model is proposed according to the characteristics of the transport network. According to the double-layer structure of the public transport skeleton network,the public transport hubs and the multiple public transport passenger flow demand points around are connected to fill the blind area of public transport. A connection structure of weaving the transport network by passenger flow point of bus,setting the transport hubs by the transport network,and complementing the bus lines by the transport hubs is set. The double-layer digital model of public transport network is established. The set of strong attraction points of public transport passenger flow is constructed. The sets of the strong attraction points of public transport passenger flow and feasible routes are determined to form points of feasible route sets,so as to balance the road flow by the passenger flow elements. An initial feasible solution close to the optimal solution is obtained by the actual data statistics,and then the convergence is verified to obtain the optimal solution. The experimental results show that the optimal convergence value of the system is 30,so it can determine the optimal path and provide strong theoretical support for urban public transport network planning.
