高架下地面交叉口改造优化设计

Reform and Optimal Design on Ground Intersection under Elevated Road

地面交叉口的交通顺畅安全是城市高架路设计的目标之一。城市道路改造为高架路后,地面交叉口的布置更加复杂。结合上海市虹梅南路高架下典型交叉口的优化设计,区别于常规交叉口布置,根据交叉口布置的关键因素,有针对性地提出优化改善措施,有关经验可供相关专业人员参考。

Smooth and safe transportation on ground intersection is one of the aims of urban elevated road design.The arrangement of ground intersection becomes more complicated as the urban road is reformed into elevated road.Different to the arrangement of routine intersection,according to the key element of intersection arrangement,this paper is combined with the optimal design on the typical intersections under the elevated South Hongmei road,and pertinently proposes on improvement measure.The experience can be the reference for transportation engineers.
