客货混行信号交叉口货车专用左转车道设置方法

为了寻求客货混行交叉口货车专用左转车道的设置方法,依据效率原则,对比分析了设置货车专用左转车道前后的饱和释放流率,给出了关于饱和流率修正系数的货车专用左转车道设置临界条件。针对实际情况,结合仿真手段给出了不同转弯半径和混行比例条件下修正系数的两类计算方法。最后依据交叉口的几何特性,给出左转车道右置的几何临界条件,可以为客货混行交叉口货车专用左转车道设置提供理论依据。

Setting methods for truck exclusive left-turn lane on the cars and trucks mixed signalized intersection

To seek the setting method for the truck left-turn lane on the mixed passenger cars and trucks traffic intersection,the saturated flow rate of set the truck left-turn lane before and after was analysed comparativly.The critical condition was given about the saturated flow rate correction factor based on the principle of efficiency.According to the actual situation,two methods of correction coefficient calculation were given with simulation under the different turning radius and mixed radio.Finally,the geometric critical condition of left-turn which set right was given based on the geometric characteristics of the intersection.The result provided a theoretical basis for the truck left-turn lane on the mixed passenger cars and trucks traffic intersection.
