综合交通体中立交改建设计思路

Design Ideas about Overpass Reconstruction in Comprehensive Traffic System

道路作为地铁、公交等公共交通的重要载体,在城市综合交通体中发挥着重要作用。地铁的修建,必然需要对所经道路进行改建,国道205(深圳段)改建工程正是地铁龙岗线修建提出的改建要求。在此项综合交通一体化的设计过程中,既有立交的改建是"痛"还是"通",是整个综合交通设计环节中的重点和难点。

As the important carrier of public transportation, roads play a significant role in the urban comprehensive traffic system. Building new metros certainly need road reconstruction where the metros pass. The Shenzhen section of national road 205 improvement project is the requirement of the construction of the Longgang- line metro. During the design process, whether the reconstruction of the existing overpass can make the traffic smooth or not is the key point and also the difficult point in the whole comprehensive traffic design.
