摘　　要：针对我国混合交通的特点,提出一个新的车辆行为模型,模型由跟驰模型、邻车影响模型和换道模型共同组成.在新模型中将车辆的跟驰状态划分为一般跟驰和自由行驶,充分考虑了驾驶员的反应延迟.同时,鉴于多车道间车辆的相互干扰,还建立了邻车影响模型,探讨同向及对向的相邻车辆对驾驶行为的影响.运用面向对象开发环境VC++6.0对模型进行软件实现,将仿真计算结果与已有的实测数据进行对比,取得了较满意的结果,证明所建模型符合实际情况.Aiming at the mixed traffic flow in China, a new vehicle behavior model was established. It was made up of the car-following model, lane-changing model and nearby vehicle＇s effect model. In this new model the car following state was divided into normal following state and free driving state. The drivers＇ response delay was also considerate. When a vehicle is running on the multilane road, there is much influence coning from the other cars. So the author built a nearby vehicle＇s effect model to discuss the nearby vehicle＇s influence both on the same side and the opposite. In the end, this model is implemented by the OO Programming Language Visual C＋＋6.0. Compared the simulation result with the field data, conclusion is satisfied. It is shown that the vehicle behavior model is suitable for our urban traffic systems.
