城市道路平面交叉口优化设计与评价研究

Design Optimizing and Evaluation of Urban Crossroads

随着社会经济的发展,城市道路开始变得拥挤。交叉口是各类交通流的集散地,交叉口设计状况直接关系道路交通的通畅程度。尤其是平面交叉口,成为影响城市道路交通的重要因素。伴随着私家车数量的增多,城市道路交通量也在不断增加,原有的平面设计已远不能满足城市发展的需要,加强城市平面交叉口优化设计与评价研究工作十分必要。文章就此展开讨论,并分析了平面交叉口交通特性等问题,指出加强城市道路平面交叉口优化设计与研究成为当务之急。

With social and economic development, urban streets become increasingly crowded. As intersections are the hub of various traffic, the design of intersections is directly related to the smoothness of traffic. Especially plane crossroads are critical to city traffic. With rising number of private cars, urban traffic is also increasing. Original graphic design is far from meeting the needs of urban development, so it is necessary to strengthen the design optimization and evaluation of urban plane intersections. Therefore, this paper analyzes the special traffic of crossroads, noting the priority of design optimizing and study of city crossroads.
