Abstract


With the rapid development of China 's social and economic undertakings , the traffic situation in major cities has become increasingly serious , to some extent, affect the further development and improvement of living standards of the people of the urban social and economic system . Conventional urban public transport as an important part of China 's urban transportation , has been more and more attention has been paid . Goal to improve the conventional city bus service levels , the bus demand forecasting of conventional urban public transportation system planning Transit network optimization technology , the bus station planning three key issues for in-depth study . First , for the defects of the traditional status quo bus OD trip matrix calculation method , the first single- bus lines as the research object , according to the number of guests of the site up and down , the the structured model backstepping single bus lines and passenger OD matrix . Equal to the probability of passengers in the car to get off of each transfer site , and get off at the probability of transfer of passengers under the assumption that the transfer site can transfer per unit time is proportional to the number of vehicles , deduced passenger bus travel up to the completion of a transfer of public transportation network passenger OD trip distribution matrix . Then, for the first time will be the time distribution of the introduction of Transit network optimization , proposed the concept of a public transportation network time coverage and of its passengers to reach the bus station was ideal Poisson distribution the total grid frequency calculation model based on time - space joint coverage of this new concept . Then , both from the social and economic benefits to consider using the linear model , based on time - spatial coverage of the public transportation network optimization model , and model evaluation , given the model 's solving ideas . Finally , the paper focuses on the bus the middle of the site the best station from the type and scale of the problem , more in line with the middle of the development status of China 's conventional public site spacing model is derived . Obtained through the analysis of two important factors in the dock of intermediate sites and urban land use development intensity based on the intermediate site type and scale model of effective berths number of bus and recommended values ??of the model parameters is given to solve China 's largest city center area bus double-track coefficient larger sections of the stops to set a difficult problem . Then planning practice based on a step-by-step combination of macro- control transit hub location models and methods .
