摘要： 交通拥堵状态下车辆行驶速度低于驾驶人期望车速，引发驾驶人变换车道以获得更好的行车 空间，由此导致不同程度的交通冲突。首先分析交通拥堵对驾驶人换道行为的影响，依据导致的交 通冲突数和冲突程度将换道驾驶行为分为三种类型。基于大量实测数据，分别研究小型客车、大型 客车、小型货车在交通拥堵状态下的车道变换特性，构建三种类型换道比例与交通拥堵压力系数的 关系模型。结果表明，交通拥堵对三种类型车辆的换道行为均产生显著影响；相比小型客车和大型 客车，小型货车不同类型换道比例分布更加离散。

Abstract： The lower-than-expected driving speed under congested traffic makes some drivers change lanes frequently for potential higher speed, which triggers traffic conflicts. By analyzing the impact of traffic congestion on drivers’lane-changing behavior, this paper presents three types of lane-changing behavior based on the number of traffic conflicts and their degree of consequent impact. Through discussing the characteristics of lane change by vehicle type (minibus, large bus and minivan) under traffic congestion, the paper develops the models to show the relationship between the proportion of three types of lane-changing behavior and the level of traffic congestion with the collected massive data. The results show that traffic congestion has a significant impact on the three types of lane-changing behavior. Compared with the lane-changing characteristics of minibus and large bus, the distribution of lane changing proportion by minivan is more dispersed.
