出租车合乘路径选择与费率优化模型

摘要

在现有的出租车合乘研究工作中,对合乘者的费用分担与路径选择基本不进行同时优化,且较少考虑驾驶员的收益.以公平性为原则,综合考虑驾驶员与出行者利益,以出行者时间费用成本最小为目标函数,以保障驾驶员合理收益为约束,构建出租车合乘路径选择与费率优化模型.并针对模型特点,设计相应的遗传算法对其进行求解.算例分析表明,模型计算的路径与费率能保障驾驶员和出行者双方的利益.%In present researches on taxi-pooling, few model is adopted to optimize fare share and route choice simultaneously, and the driver earnings are not considered. In this paper, benefits of both sides are taken into account on the principle of equity. Taking the minimum time cost of travelers as an objective and the drivers' reasonable income as constraint, we establish a route choice and fare optimization model for taxi-pooling. According to the characteristics of the model, an algorithm is designed. Using an example, the model is tested and the result shows the rate and route choices can satisfy both sides.
