带状河谷型城市交通干道设计方案研究——以吕梁市离中快速通道为例

带状（组团）河谷型城市广泛分布于我国山地、丘陵地区，此类城市空间狭长，土地资源稀缺，轴向道路交通矛盾突出。为探讨此类城市交通干道的设计要点，以吕梁市离中快速通道为例，从解决交通问题、集约利用土地资源角度出发，同时兼顾服务性交通需求，对其设计方案进行了细化研究。研究结果可为相似工程提供借鉴和参考。

Research on Design Scheme of Traffic Artery in Zonal Valley City for Lvliang City

The zonal (cluster) valley type of cities is widely distributed in the mountainous and hilly areas in China. This kind of city has the long and narrow space, scarce land resources and prominent axial road traffic contradictions. For the discussion of the design essentials of the traffic artery in this kind of city, taking Lizhong Express Channel in Lvliang City as an example, from the perspective of solving the traffic problems and intensive use of land resources, and meanwhile to balance the service traffic demand, its design scheme is studied in detail. The study result can provide the reference for the similar projects.
