| 摘 要： | 车辆跟驰在近几年的交通工程与安全研究中越来越重要,现有的交通流理论中跟驰模型较少考虑道路的几何形状(坡度与弯度)对跟驰行为的影响,从车辆在有坡度与弯度的道路上行驶的受力作为出发点,分析得出车辆在道路转弯半径不同时的安全行驶的条件,在坡道上行驶时汽车牵引力以外的加速度以及习惯性的行驶行为,并通过这些因素对跟驰模型进行了修正,从而得到了一种适用于具有弯度与坡度道路的跟驰模型,最后用改进后的模型进行了仿真实验,证明了使用该模型进行跟驰仿真研究是可行的。

| Abstract: | In recent years,car-following has become increasingly important in traffic engineering and safety studies.The car-following models proposed before do not include the effects of roadway geometry on drivers.Analyzing the forces on cars on road with curves and slopes,this paper obtains the condition of safe driving on road with different swerve radii,the acceleration due to slopes,and the custom driving behavior.This paper uses such factors to modify the car-following model,according to the actual following behaviors.The new model is employed in a simulation test to prove the feasibility of the model. |
