通行有轨电车的平面交叉口设计要点分析

Analysis on the Design of Grade Intersection Where Trams Pass

在公共交通方式日趋多元化的背景下,现代有轨电车以运能大、速度快、乘车环境舒适以及美观等优点已被引入国内外很多城市,在创建公交都市方面发挥着重要作用。平面交叉口是道路工程设计中的重要内容,是城市路网中交通流转换的节点。有轨电车介入后,增加了交叉口的复杂程度,做好有轨电车介入条件下的交叉口设计显得尤为重要。笔者从道路工程和交通工程的设计角度出发,以有轨电车布设方式、交叉口竖向设计、路口混行段路面搭接处理以及交通组织设计等问题作为研究重点,梳理分析、归纳总结,相关结论可为类似项目提供参考。

In the background of increasingly diversified public transport modes,modem tram has been introduced into many cities at home and abroad because of the advantages of large capacity,fast speed,comfortable riding environment and beautiful appearance.It plays an important role in building transit cities.Grade intersection is an important part of road engineering design and the node of traffic flow conversion in urban road network.The complexity of the intersection is increased by the trams so it is particularly important to design the intersection where trams pass.From the perspective of road and traffic engineering design,the author focuses on the layout of trams,vertical design of intersections,pavement overlapping treatment of mixed traffic sections at intersections and traffic organization design and draws the conclusion.The relevant conclusion can provide reference for similar projects.
