摘要
在我国社会的高度发展下,城市化进程显著加快,国民生活水平随之提高。近年来,我国道路车辆逐年递增,城市交通成为人们关注的热点话题,城市交通状况也成为衡量城市发展的关键指标。为有效改善交通拥堵问题,市政道路桥梁、隧道工程建设逐年增多,城市快速路作为缓解交通压力的关键举措之一,其建设程度决定着拥堵问题是否得以有效解决[1]。目前,我国城市快速路出入口设计存在较大问题,出入口设计水平决定着快速路汇流、分流能力,介于此,本文围绕城市快速路出入口设计展开叙述,以期为相关领域提供借鉴和参考。
Under the high development of Chinese society,the urbanization process was significantly accelerated and the national living standard was improved.In recent years,Chinese road vehicles are increasing year by year,urban traffic has become a hot topic,and urban traffic status has become a key indicator to measure urban development.In order to effectively improve the traffic congestion problem,the construction of municipal roads,bridges and tunnel projects has been increasing year by year.For urban expressways,as one of the key measures to relieve the traffic pressure,the construction degree determines whether the congestion problem can be effectively solved.At present,there are many problems in the design of urban expressway entrances and exits in China.The design level of entrances and exits determines the convergence and diversion capacity of expressways.This paper focuses on the design of the entrance and exit of urban expressway,in order to provide reference for relevant fields.
