干线公路快速化路线总体设计研讨

Rapid Design for Trunk Highway

随着城市规模不断扩大,城市周边干线公路日益面临着城镇化干扰的问题,人流、车流量迅速增加,造成了部分路段交通拥堵、事故频发。如何将干线公路进行快速化改造,成为一个迫切需要解决的课题,该文从设计的总体思路、横断面设计、平纵面设计、设计车速等方面对干线公路快速化设计进行探讨。

With city scale expanding continuously,trunk highway around cities facing broblem of urbaniztion interference.Increasing of traffic flow and people flow leads to traffic jam and frequent accidents.It is very important to transform trunk highway.This paper aralyzed whole thinking,cross section design,designing speed of trunk highway tranformation.
