The Research Of The Net Layout And Junction Planning On The Railway Participating In The City Transportation

In recent years, along with the social economics'fast development, the city transportation jams and the environment worsening are becoming increasingly outstanding. So the orbit transportation's characters can satisfy modern people's requirement for persistence development of traffic, such as great capacity, celerity, comfort, safety and less pollution etc.Because construction of urban railway can drive exploitation and using along the line, and lead development of the city's layout towards reasonable direction. So the urban railway becomes efficient to solve the traffic problem in big cities which is increasingly outstanding.But mass-construction of urban railway is still not practicable in most Chinese cities because of the too-much high cost of construction. Meanwhile, along with the acceleration of civilization and extending of territory in cities, many hinges and other lines of them were closed in cities terrorist. So they lost their former position and function which causes the capacity and equipments are leaving unused.Under the dual background, aimed at the participation of national railway in urban passenger transport and based on the situation and character operating home and abroad, this paper makes a demonstration and expatiation.There are two parts in this paper. The first one analyzes the possibility and necessity of the participation of national railway in urban traffic, and also advices the layout of urban railway and the planning of junction between urban railway and other traffic ways. The second one takes Chengdu national railway hinge as an applied example using the methods in the first part and makes a specific planning and demonstration for the participation.
