基于方格的道路网络中出租车乘客效应函数模型和优化策略

摘要

为解决乘客根据最优策略进行选择乘坐出租车的问题,提出了一种基于方格道路网络的乘客效用函数模型.假设出租车司机和乘客在网上都可以清晰地看到和知道彼此的地理位置和目的地的情况下,分析了可能出现的三种情况,构建了相对应的三个等效函数.出租车的速度和出租车与乘客的距离能够影响这几个等效函数.仿真结果显示,出租车的速度和出租车到乘客的距离确实是2个重要的自变量,与之前推导的理论和策略符合.乘客能够根据不同的出租车与它位置的距离判断出最优策略,从而选择最优的出租车搭乘.%The customer utility function models in cell-based road network are proposed to solve the problem for customers taking taxi according to the optimal strategy. Taxi drivers and customers have known the location and destination. Three situations are analyzed in the cell-based network and the corresponding utility functions are proposed. The speed of taxi and the distance between taxi and customer can affact the utility functions. In terms of simulation,the speed of taxi and the distance between customer and taxi are the important independent variables in line with the theories. Customers can choose the taxi according to the distance between customer and taxi which will provide the optimal strategy.
