特殊地形城市道路交通面临问题研究

具有特殊地形、地貌特征的城市道路交通由于受到了山脉、河流、特殊的固定自然物的限制,城市的布局往往形成分散、组团式和带状的特点,呈现出了各种交通模型的非线性、非周期性等特征,该文详细研究了该类城市道路交通面临的问题,重点分析了特殊地形、路网分布、传统的交通指挥系统对特殊地形城市道路交通的影响。以河谷型城市兰州市的地貌特征为例,分析了这些问题及因素,并提出了解决这些问题的方法。

Study on Problems of Urban Road Traffic in Special Terrain

The special terrain and topography of urban road traffic presents the nonlinear and non-periodic characters of various traffic models because of the limitation by the mountain chain,rivers and peculiarly fixed natural objects in the result of the city layout frequently to form the characteristics of scattered distribution,clustered and belt shape.The article studies in detail the problems of the road traffic in this kind of city,focuses the analysis on the influences of special terrain,road network layout and traditional traffic directing system on the special terrain of urban road traffic.Taking the topographic characteristics of the valley-city Lanzhou as an example,the article analyzes these problems and factors,and puts forward the methods to solve these problems.
