Research On Public Transportation Network Planning Of New Urban Districts

New urban district is an inevitable result of the development of city and an indispensable component of the city. It's a basic mode which the urban scale expands. Its planning related to the whole success of the pace of urban development directly, at the same time its' public transport planning is an more important part for the economic and social development. The traditional public transport planning has higher accuracy because it's based on a large number of surveys and four-stage method. However, in the new urban public transport OD forecasts, the traditional method encountered problems. The new urban district has on construction; we can't do any investigation about it. Therefore, to establish suitable traffic forecasting model for the new urban areas is very urgent and important.This paper researches on new urban districts. On the basis of analyzing the existing research outcomes, comparing and analyzing the differences between new urban districts and old urban districts in traffic forecast, considering the features of traffic forecast for new urban districts, it starts form the location land use information of traffic zones, and establishes traffic production and distribution forecast models which are fit for new urban districts.This paper includes five parts. First of all, its analyzes the type of new urban area, then determines the research area-extensive new area; Second, I have a clear target for the development of public transport; Third, location potential energy is presented and the location land use information quantification model is established. Combination features of new district, a traffic and distribution model is established, and then calculated the public transport OD of new area. Fourth, analysis of the basic principles of public transportation network planning and ideas, put forward a combination of the status quo methods of transit network layout; Finally, this paper has an example-Fengwei New District, at the conclusion of its public status made a public transportation network planning program for the planning year.
