针对车流优化速度模型在侧向偏移方面的尚存缺陷,提出了考虑侧向车影响及侧向偏移的优化速度模型。综合考虑了车辆侧向偏移的影响因素,基于刺激-反应机制和车辆跟驰理论,系统分析车速优化模型,协同考虑换道车辆侧向偏移的影响因素,建立车辆行为特性的优化速度模型,并在典型的减速换道场景中进行仿真分析。结果表明,考虑侧向偏移的优化速度模型能够更加贴合实际交通状况,切实体现车辆驾驶行为特性规律,研究成果为车辆平稳运行和安全换道提供理论依据。

In view of the vehicle flow optimal velocity (OV) model in the lateral offset aspect still have the flaw, OV model considering the effect of side car and side deviation was Proposed.Comprehensive consideration the influence of vehicle lateral offset,based on stimulus-response mechanism and vehicle following theory to analyze vehicle optimization model systematically,considering the influence factors of lateral deviation of lane changing vehicles, establish OV model and take simulation analysis in a typical deceleration lane change scenario.As a result,OV model considering lateral deviation can fit the actual traffic condition better,embody the law of driving behavior. The research results provide theoretical basis for the smooth running and safe lane changing of vehicles.
