常规公交组合调度优化研究

为满足公交企业管理运营和乘客二者共同的利益需求,达到资源合理配置,结合现场调查数据,借助Matlab进行公交OD客流量的反推计算,同时在确定大站快车开行的站点的基础上,分别得到大站快车和全程车调度的OD客流量,然后建立包含大站快车和全程车两种调度形式的发车间隔优化模型. 以北京某公交线路作为研究对象,选取平均运行速度、开行班次、停车次数、公交运营成本等指标进行敏感性分析. 结果表明,模型在满足乘客的需求的同时,降低了公交企业约25%的运营成本.

Optimization of Combinational Vehicle Scheduling for Public Transit

In order to meet the needs of both bus enterprise and passengers for reasonable allocation of resources, the passenger flow OD matrix is calculated on the basis of the survey data. At the same time, passenger flow OD matrix of the two vehicle scheduling is got by the determined express bus stops. Then bus scheduling mathematical model is established, which contains the express bus and the full dispatching schematic. Sensitivity analysis of the model is achieved by the selected elements such as the average speed, the number of bus used, the times of bus stops, operating costs. The conclusion indicates that the combinational scheduling can reach the needs of passengers and reduce 25% of the enterprise operation cost.
