客货分离道路背景下大货车右转弯车道设计方法

Design Method of Right-turning Lanes for Large Trucks in the Background of Passenger-freightSeparation Roads

针对客货分离道路交叉口节点的设计,考虑大货车自身转弯特性,主要从右转导流路宽度确定、考虑内轮差的非对称三心圆右转弯内弧线设计和右转弯车道一体化几何作图流程三个步骤提出新的设计方法,以实际工程为例,从道路安全性、通行效率及土地利用三个方面进行论证分析,确保大货车右转弯车道设计方法的有效性。

Aims at the intersection design of passenger-freight separation roads,considering the turning characteristics of large trucks,mainly from the determination of the width of the right-turn diversion path,the design of the asymmetric three-center right-turn inner arc considering the inner wheel difference,and the three steps of in-tegrated geometric drawing process of right-turn lane,put forward a new design method.And take an actual project as an example to demonstrate and analyze from three aspects:road safety,traffic efficiency and land use,to ensure the effectiveness of the design method for right-turning lanes for large trucks.
