Study On The Existing Problems And Development Planning Of Roadway System In Middle Scale Cities--Study Case Of Yun Cheng City

Urbanism is an important character in contemporary society.Middle scale cities are the most quickly development ones from the view of the cities scale and structure in all cities. But during the long time, middle-scale-cities planning and construction in roadway system have lack too much capital, and middle-scale-cities can't fit to the development of urban economic, so many problems have exposed.Road transportation is the main components of the city function and basic facilities and is also the essential conditions of the city relying for existence, development maintaining normal working.At the present, the planning capacity is weak, and our research is only on big city's road planning, so it is necessary to study on the Middle-scale-cities road system.First, this paper looks for the national experiences that organizing city traffic in the rodeway system, in conditions of the mobile and no-mobile number being big. Then analyzing the questions and reasons in middle-scale-city roadway system, on the base of studying characters of use-land and residents journey, transportation tools and relations of the transportation and economy development, put forward some proposes in roadway system on the base of middle-scale-city characters of basic construction and solving the new problems of city traffic.Through analyzing the relations of middle-scale-city roadway system, city land-use and land-shape ,put forward some development antidote.In the circumstance of road facilities being lack, improve the level of traffic management of city roadway system, improve traffic environment of city roadway system. Put forward some revised proposes on road-net norm of middle-scale-city road system in our country; consider the plan of isolating mobile form no-mobile in the organization of roadway system; construct revaluating system of city roadway system.At last through studying a typical case of YunCheng, put forward some solutions and measures; Through using evaluating system, evaluate, contrasts and analyses the present conditions in city roadway system and planning program.
