带状组团型城市快速路规划技术要点

Technical Essentials Points for Planning Banded Group Urban Expressway

随着中国城镇化水平的提高、城市空间规模的不断拓展,很多城市的空间结构演化为带状组团型城市,轴向交通干道数量少、交通拥堵严重、缺少大中运量公共交通等情况已经成为困扰城市交通运行、阻碍城市发展的重要问题。着重梳理了带状组团型城市的发展历程和交通特征,提出了类似城市在进行城市快速路网规划工作时需要考虑的重点内容和解决方案。

With the improvement of urbanization level and continuous expansion of urban space scale in China, many cities have been evolved into the banded group spatial structural cities. Fewer axial traffic trunks, severe traffic congestion, and lack of large and medium-sized public transport have become the important problems to puzzle the urban traffic operation and hinder the urban development. The development history and traffic characteristics of banded group cities are specially sorted out. The key contents and solutions needing to be considered for the similar cities in the planning of urban expressway network are put forward.
