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。
交通擁堵狀態下車輛行駛速度低于駕駛人期望車速，引髮駕駛人變換車道以穫得更好的行車空間，由此導緻不同程度的交通遲突。首先分析交通擁堵對駕駛人換道行為的影響，依據導緻的交通遲突數和遲突程度將換道駕駛行為分為三種類型。基于大量實測數據，分彆研究小型客車、大型客車、小型貨車在交通擁堵狀態下的車道變換特性，構建三種類型換道比例與交通擁堵壓力繫數的關繫模型。結果錶明，交通擁堵對三種類型車輛的換道行為均產生顯著影響；相比小型客車和大型客車，小型貨車不同類型換道比例分佈更加離散。

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-chang-ing behavior and the level of traffic congestion with the collected massive data. The results show that traf-fic 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 min-ivan is more dispersed.
