都市圈快速公路网规划方案探析——以重庆主城都市区快速公路网规划为例

Analysis on Planning Scheme of Expressway Network in Metropolitan Area of Chongqing

随着我国各个城市的核心区不断扩展,中心城区和主城新区加速融合,向着同城化方向发展,既有国道和高速公路已不能满足通勤交通和物流运输的需要。以重庆市主城都市区为例,通过现状条件分析,列出既有高速公路和国省干道在同城化交通运营中的问题。提出在主城都市区内构建快速公路网,形成与高速公路互补的、多层级路网结构的设想,对促进区域经济发展,优化路网结构具有一定的指导意义,对类似城市的快速路网规划有一定的参考作用。

With the continuous expansion of core area in each city of China,the central urban area and the new town are rapidly integrated towards the direction of urban development.The existing national highways and expressways can no longer meet the needs of commuting traffic and logistics transportation.Taking the metropolitan area in the main urban area of Chongqing as an example,the present problems are analyzed,and the problems in the urban integration traffic operation of the existing expressways,national highways and provincial trunk roads are listed.The assumption of building the expressway network in the metropolitan area of the main urban area and forming a multi-level road network structure complementary to the expressways is proposed,which has some guiding significance for promoting the regional economic development and optimizing the road network structure,and provides some reference for the planning of expressway networks in the similar cities.
