Study On Planning And Design Theory For External Passenger Transport Hub Of Metropolis

An external passenger transport hub(EPTH) in a city is the facility for traffic conversion, which connects inbound and outbound traffic. Although the EPTH planning is one of the very important parts in city planning process, its importance is not fully recognized. The phenomenon of emphasizing on construction instead of planning is still widespread. The EPTH planning theories and methods is still deficient.The author presented the systematic study from the macroscopic and the microscopic views, on the layout and the passenger transfer of the EPTH. The study includes the formation mechanism, layout and location selection, passenger transfer forecasting theories, cohesion system planning theories and comprehensive evaluate methods, etc.Firstly, based on the analysis of the relationship between EPTH and city development, as well as the its expanding force, the author initiated the EPTH's formation mechanism, studied the relationship between its developing process and modality, the interaction between its development and the city development in modern times. After having analyzed the current state of big cities'EPTHs, the author pointed out the direction of EPTH's development in the future.Secondly, based on analyzing the problems existing in the current EPTHs'layout and their location selecting, and with respectively focusing on old cities with intense land use and new cities with under development land use, the author initiated the restraint and non-restraint models and solutions for location selection, with the objects of minimizing the total travel time.Thirdly, the author proposed the external passenger traffic demand forecasting models and solutions from the distribution of passenger traffic inside and-outside cities.Fourthly, the author analyzed the characteristic of external passenger traffic, and built the EPTH passenger transfer mode optimization model with the object function of optimizing the mobility, accessibility and ecological impact of the EPTH. Meanwhile, passenger traffic was forecasted.Fifthly, focusing on the MRT and public transport sectors, the author initiated the optimization models and methods of the EPTH's cohesion system, respectively from the point of views of joint pattern, station, circuitry and operation. Als0, by studying the problems exists in organizing the EPTH's passenger traffic, the author proposed the according methods. Furthermore, according to the connotation and classification of EPTH's information services, the author studied and initiated the methods of optimizing the information services in EPTH.Sixthly, the author improved the criteria system of evaluating EPTH, studied the EPTH evaluation system from the layout view and the passenger transfer view. And the set pair analysis method for evaluating transfer system was introduced for the first time by the author.At the end of this paper, conclusion was drawn and the future research area was proposed.
