基于适应度的驾驶员路径选择模型及仿真

针对车辆的路径选择问题，首先描述路径选择单元的划分规则，然后从影响车辆路径选择的路径历史经验和路径最近经验入手，分别定义车辆对路径的初始适应度、历史适应度、最近适应度及路径选择行为概率，并对车辆记忆属性及其变化流程进行说明，最终给出车辆路径选择规则。在上述分析的基础上进行多次重复时间步仿真，仿真结果表明，本文给出的路径选择规则虽然相对较简单，但能够较好地模拟车辆路径选择行为，为交通仿真中车辆路径选择模型提供了一种新的思路。

Model and Simulation for Driver Route Choice Based on Fitness Function

In order to resolve the route choice problem in traffic simulation, with the route choice history experience and route choice recent experience of driver, the initial fitness, history fitness, recent fitness and route choice action probability are de- fined, then the memory property of driver and changing process are described, at last, the route choice rule is brought up. On the basis of above analysis time step simulation are carried out repeatedly, the simulation result proves that the ride is simple and ef- fective, but provides a new way for the driver route choice model in traffic simulation.
