城市高架桥下地面道路交通组织设计

Traffic Organization Design of Ground Road under Urban Viaduct

许多城市道路通过在原有道路上修建高架快速路系统来构建多层次的道路交通系统,以满足城市交通的需求。城市高架桥下地面道路与普通道路相比,受到空间、视野等诸多因素的限制,因此,其交通组织的设计显得尤为重要,直接影响到桥墩位置及地面道路方案。以乌鲁木齐市阿勒泰路高架桥下地面道路为例,对城市高架桥下地面道路的交通组织进行了分析和探讨。

Many urban roads are constructed by constructing the elevated expressway system on the existing roads to build the multi-level road traffic systems in order to meet the needs of urban transport.Compared with ordinary roads,the ground roads under the urban viaduct are limited by many factors of space,vision and etc.Therefore,the design of its traffic organization is particularly important,and directly affects the pier location and the ground road scheme.Taking the ground roads under the Altay Road Viaduct in Urumqi as an example,this paper analyzes and discusses the traffic organization of ground roads under the urban viaduct.
