车道变换行为对交通流运行速度影响的研究

Study on effect of lane-changing behavioral characteristic to velocity

为解决车道变换行为对交通流运行速度影响的定量分析难题,从观测数据的整理分析结果出发,揭示了车道变换行为与交通流运行速度的关系,提出速度判断因子的概念,给出基于典型城市的观测数据的速度判断因子推荐值。基于车道变换行为发生率和速度之间的关系,联立交通流理论中关于速度和交通量的关系模型,构建了车道变换行为对交通流运行速度的影响模型,并进行参数标定。最后给出车道变换行为对运行速度的影响量值。

To solve the problems of quantitative analysis the impact of lane-changing to traffic flow speed, based on the analysis of observation data, revealed the relationship between lane-changing behavior and traffic flow speed, a factor to determine the speed of the concept was given based on typical of the city of observational data to determine the speed factor values. Based on the relationship between lane-changing behavior and speed, even legislated the model on the theory of traffic flow and the relationship between speed and lane-changing behavior to propose a impact model, and calibrated the parameters, At last, given the value of the effected.
