Analysis of the Influence Factors of the Lane Change Duration on Expressway

Lane change behavior is a common driving behavior on expressways and the duration is a fundamental parameter for microscopic traffic simulation models. This paper analyzes the effects of different variables on the duration of lane changing behavior. Two UAVs were used to get the accurate status information of each vehicle on the expressway. Parameters such as speed, acceleration, lane position, coordinates, and 538 complete lane change behaviors were extracted. The main reason for the lane change maneuver was the low speed of the leading vehicle. Drivers took risk to change the lane even when the relative distance between the lane change vehicle and the lag vehicle in the destination lane was small. This paper can provide a better understanding of lane change behavior and can be used to develop a more reasonable lane changing behavior in China.
