探讨了影响双向八车道高速公路车辆运行规则的流量、客货车比以及超车方向等因素,基于流量、平均速度和速度标准差变量构建安全函数,基于流量、速度和时间变量构建效率函数,并从安全与效率平衡角度出发,通过微观交通仿真软件VISSIM对不同流量、车道功能划分及超车方向组合而成的不同交通条件下的车辆运行规则进行仿真,得到了适应于不同交通条件的双向八车道高速公路车辆最佳运行规则,分析了超车方向对车辆运行安全和效率的影响。
This paper discusses the factors such as flow rate, valet ratio, overtaking direction and other factors that affect the operation rules of two-way eight-lane highway vehicles. The safety function is constructed based on traffic, average speed and standard deviation of speed, and the efficiency function is constructed based on traffic, speed and time variables. Safety and efficiency of the vehicle. Based on the micro-traffic simulation software VISSIM, the running rules of vehicles under different traffic conditions with different traffic flow, lane division and overtaking direction are simulated, and the bidirectional eight-lane high speed The best operation rules of highway vehicles, and analyzes the influence of overtaking directions on the safety and efficiency of vehicles.
