Urban Public Transportation Network Planning Research

Urban public transportation network design is the major part of the urban passenger transportation planning. It is significant to study the UPT planning. The UPT forecast methods,systemic constrains of routes and the whole network,destination function,the methods route design and network optimization have been studied in this article.The methods of forecast the public transportation strategy:"Maercofu" and it's deformation are put forward on the basis of analyzing the history public transportation data. The methods of forecast the public transportation O-D is make out:it is on the basis of the figure of the transit passengers get on and get off the bus on the spots. The methods and procedure of election the destination of public transportation evolution are expounded. The systemic and synthetic research of constriction of public transportation route and network is made. The hieroglyphic methods of UPT stops & stations planning,that is,the optimization of the bus stops space is studied.The road system,which provides only for the bus operation is researched in this article. The methods of how to condemnation constructing the bus-operating road system or not is excogitated. On the basis of summarization the history methods of common public transportation network planning,put forward of the propping route design methods.At last,the outcome of this article is used in the changsha public transportation planning and get the satisfied consequence.
