A Lane Change Model with the Consideration of Car Following Behavior

Abstract

Lane change model is a hot issue of microscopic traffic simulation and active safety. Among current studies, most of lane change models based on vehicle kinematics hypothesize that when the vehicle of adjacent lane changes lane, the following vehicle of target lane keeps uniform motion. However, this hypothesis does not match with the real lane change scenario. In the paper we put forward a lane change model with the consideration of car following behaviour, and focus on kinematic behaviour of the lane-changing vehicle in the process of accelerated lane change. We construct a lane change scenario and derive a reasonable lane change model, and finally testify the model performance by MATLAB simulation. The results show the new lane change model is simple and reasonable, which can fit with the real lane change scenario. In addition, the proposed model can also provide some reference lane change algorithms for Intelligent Vehicle.
