摘要
依据珠海市公交线网的拓扑特点及公交乘客O-D量(起点、终点的客流量),提出了以直达乘客运输量最大为目标函数的公交线网优化模型。运用数学规划中求解指派问题和最短路问题的算法,对公交线网优化模型进行求解,得到最优公交线网规划方案。此外,还运用了线路客流分布均匀性检验方法验证了优化方案的正确性。
After analyzing Zhuhai current transit, an optimization model on transit network is proposed in which the objective function is to maximize quantity of nonstop passengers via taking the method of ＂Assignment problem＂ and the shortest path method in mathematical programming. Besides, the methods of the inspection of passengers＇ well-distribution are used to verify the optimal result.
