| 摘 要： | 车辆的行驶行为可分为自由行驶、跟车行驶和换车道行驶等三种不同行为。换车道行驶过程中，车辆容易发生侧刮、对向相撞、追尾等交通事故。根据车辆运动规律，提出了换车道过程中三个避免碰撞约束条件，选择运行速度和加速度为安全评价指标，通过二阶加法评价方法计算危险系数，确定了不同换车道危险系数的安全等级，并以某山区高速公路为例，阐述了换车道安全评价的分析与应用。

| Abstract: | Vehicle travel behavior can be classified as free operation,car-following operation and lane-changing operation. During vehicle lane-changing,there exist several traffic accidents,such as sideswipe,angle,rear-end and so on. Based on the theory of vehicle dynamics,the paper puts forward three vehicle-crashed restrictions by which vehicle can change lane safely.By selecting the operation speed and acceleration which can reflect the accident severity,an two-order audit method is introduced to calculate the lan... |
