针对现行交通仿真模型中跟车模型和超车模型的不足之处，通过分析驾驶员交通行为的基本特性，指出了 驾驶员特性对车辆跟驰行为、换车道行为的影响，提出了判断车辆跟驰状态的合理指标及指标值的确定方法，最后 分析 了驾驶员类型对换车道模型的修正方法。(According to the current traffic simulation model with inadequate vehicle model and overtaking model, by analyzing the basic characteristics of drivers' behavior, points out the characteristics of the driver's car following and lane changing behavior behavior influence, and put forward the method of determining reasonable index to judge the car following state and index value, finally analyzes the correction method of the driver the type of lane changing model.)
