The Study On The Planning Of The Network Of Highways In Cheng-Tang-Qin District

The highway traffic and transportation undertaking in China has been making a big development since over twenty years of reformation and opening doors, especially in the period of"Nine Five"and"Ten Five", the instruction of the high level national main highway is making giant strides, and is reaching a huge achievement. It's been strongly promoted the economic development of China. However, some problems are creating at the same time when the traffic condition of cities and counties are getting better and the highway construction is giving a huge contribution to the national economy. The problems are the defects that indicate in the system of highway net scheme, the target and the methodology, can not direct well the current highway construction and the development. It causes some highway program couldn't give the obvious benefit, some program construction even brought a negative affect in the region development.This article is focus on the popular and difficult questions that exist in the highway net scheme development theory and reforming practice, and need to be investigated urgently. The topic has an important value in both theory and utility. This article goes through the evolution system analyses of regional towns'space construction, develops the traditional analyzing fields in highway net scheme, extends the vision to the regulation of the regions'space construction developing evolution, and builds a theory supporting system for exploring the essential decisive factor of highway net formation and development. Through the investigation of the impacting regulation between the traffic and the region towns'space evolution, builds the theory basis for exploring the theory and the method in the highway net layout of the region towns'space. Through the investigation of the space gather and disperse effect in the highway economic band, explores the evolution system of the highway economic band, and makes some illumination significance in making the policies about how to make the highway's construction to promote regions'economic development. Through the investigation in the method of the highway net layout of the region towns'space construction, introduced the conception of the region towns'space development degree, the central city degree and the space economic connection intensity. It's solved the drawback that appeared in the former highway net layout scheme. Combining is the practice of the Qin-Tang region highway net layout scheme as the positive analyze and investigation of the method that is referred in this article. Through the practice analyzing can see that the method of the highway layout scheme that referred in this article has a good feasibility in directing the current highway construction, and also has a creative significance in both theory and practice of the regional highway net layout scheme.
