【摘要】 研究在高速道路中慢车对其他车辆通行的影响,从安全行驶间距入手,建立单线临界流量与车辆变道纵向速度和慢车速度的关系式,如单线行车流量大于该临界值则可能发生拥堵,分析了几种情况下单线临界流量变化,为道路管理者及车辆驾驶者提供一种理论参考.更多还原

【Abstract】 Studied that a slow car effect on other cars traffic in high-speed road,starting from the safe driving distance,establish the relationships between the critical flow rate in single lane and the Longitudinal Longitudinal speed and the speed of slow car,such traffic jam which may be occur when the flow rate in single lane is greater than the critical flow rate in single lane,analysing the change of critical flow in single lane several conditions.This paper can provide a theoretical reference for the road managers and the drivers.更多还原
