信号交叉口直右共用车道通行能力研究

为了弥补国内对直右共用车道通行能力研究的不足,在现场观察的基础上,分析了其交通流运行特性.根据实测数据,运用统计学中的T检验法对不同转向车辆的饱和车头时距进行了分析,发现直右共用车道上直行车辆和右转车辆的饱和车头时距存在显著性差异；然后运用饱和流率修正理论和概率论方法,给出了适用于我国现阶段道路交通条件下直右共用车道通...

Capacity Research on Shared Through-Right Turn Lanes at Signalized Intersections

In view of the insufficient researches on shared through-right turn lanes capacity at signalized intersections in China,the paper investigates the traffic operation of shared through-right turn lanes and analyzes the traffic characteristics.Based on the measured data,the saturation headway of vehicle for different shift is analyzed using the T-test statistical method.that the results show that a significant difference between the saturation headway of through and right-turn vehicles are existed.Then,a theor...
