基于换乘系统经济效益最优的公共交通调度问题研究

在对国内外研究现状分析的基础上,从经济效益最大化的角度研究了常规公交线路与城市轨道交通线路的协调换乘问题。为了得到此类换乘系统经济效益最优目标下的常规公交线路调度优化方案,建立了常规公交与城市轨道交通换乘系统总经济效益模型;针对采用的莘庄换乘站算例中车辆到达特性,运用概率论确定了常规公交车辆到发概率分布,在此基础上对模型进行求解;最后,应用此模型对上海莘庄地铁站轨道交通与常规公交的换乘进行优化,提出车辆调度优化建议。

Optimal Public Transport Dispatching on the Economic Benefit of Transfer System

By analyzing the current situation of public transport of the world, this paper mainly discusses the economic problems of the bus--urban rail coordinated transfer system. In order to get the optimal control schedule under such economic conditions, a model of cost in bus--urban rail transfer system is developed. According to the actual data gained from Shanghai rail station, the distribution identity of the bus arrival is determined, and the model is used for rail vehicle dispatching in Shanghai Urban mass transit.
