Sustainable Planning Theory And Method Of Urban Transportation System

Sustained Development is a widely accepted mode. There has been continues research and discuss on the sustained development of urban transportation system. The key project of the National Natural Science Foundation of China (NSFC), which named .the Research on Sustained Development of Urban Transport System., has begun. It indicated that we academic havedeepened into the sustained developing theory. The article based on this project and analyzed the sustained developing theory and means on urban transportation. Firstly, the article focuses on the planning of sustained developing theory frame of urban transportation lay out. It analyzes the history of urban transportation planning development and the traditional characteristics of planning and its shortcomings. It concluded that the simplicity of planning goals and the .four-stage. method lack some important qualities, which is required in the modern planning; such as it lack the consumption and environment evaluation, not embodying the .for people. sake. and lake guarantee system. The article proposed the principles of sustained development and designed a theory system of urban transportation planning in accordance with the situation of our country. It also designed the function of each individual module in the system. The arrangement and common procedures of sustained developing planning had also been mentioned. The article advanced the planning goals, which should satisfy demand, optimize resources utilization and improve environment quality. They are divided into road networks dimensional indexes, transportation quality indexes, roadway environmental indexes and resource consumption indexes; these indexes are quantitative. At the same time, according to the situation of guarantee system research shortage, it concluded that the guarantee system is a most important aspect of sustained developing of urban transportation system. According to the sustained developing principles, it brings forward the investigate method must accord with the sustained developing principles and the investigation goal is not only establishing a data base, but also finding out the exist problems in the transportation system. It advanced the investigating methods by dividing it into two parts, data collection and field investigation. The efficient way to do the investigation is studied and the data base, which is based on the GIS technology, is mentioned. They together combined the methods of present urban transportation system analysis. The most important characteristic of urban transit is the structure of it. In our country, the transit structure must base on the real facts such as the economic is developing, the capital is hard up, the resources per capita is scare and so on. These determine that the developing mode must be compressed cities and it is important to develop city itself in this method. The author brings forward the different transit structure values in according to different cities with their land usage situation by taking foreign country.s experience and lessons and by delving our country.s facts. It has been experiencing the structure changing phase for our country and the mega polis and big cities need to develop their own transit...
