Study On The Passenger Corridor Of The Corridor Valley Pattern City

In recent years,as C hina’s urbanization and motorization process continues to accelerate,expanding urban space,the number of motor vehicles continues to grow. Contradiction between traffic demand and traffic supply has become increasingly prominent,environmental pollution and noise pollution is also increasing. Starting from Beijing in October 1969 to build the first subway line,marking the country has entered the era of development and construction of the subway in Shanghai,Tianjin and other places have built successful,to the cities is now in a big advocate TOD guide transit development model. Now,not only in the capital city subway,Some economic and demographic conditions meet two or three cities have been successively built successfully in the latter part of the operations are often played an active role. However,many areas in western and southern part of C hina is developed along the river,some of whom,like Lanzhou, Xining,the capital city of this,but from now on urban development,traffic pressure is also growing,urban rail transit construction is imperative.The corridor valley pattern city restricted geographica l conditions, with its unique spatial expansion mode and stage, the formation of the corresponding land use patterns,the decision has a relatively high proportion of b us travel. This article is dedicated to the research and study of passenger corridor in the corridor valley pattern city,and the results of its aggregation effect relative to the plain city traffic corridor stronger, longer average travel distance,,is conducive to public transport links layout and operation. This article first on the corridor valley pattern city to make specific definitions, then analyzes its special spatial form, land use and employment. Then, from the urban road network, bus network, travel temporal and spatial distribution, respect traffic structure analyze river city special transport properties, and city bus lines length determines the River Road length, and regular bus and rail traffic to do a comparison, rail transit River Road city more conducive to the length of the stretch. Finally, based on the traditional "four stages" Traffic Volume Forecast model, the establishment of a grid + ring, radial loop and River Road with three kinds of idealized city shaped pattern. Traffic Distribution Forecast gives a different phase of the three cities the average trip distance a nd cell attractive; Traffic assignment stage reveal that model produces different bus passenger corridors and texture; the city after the introduction of rail lines, creating a competitive conventional bus and rail, and the establishment of a joint model between the two, and make relevant algorithm, combined with case study on Xining the corridor valley pattern city’s passenger corridor aggregation effect stronger and more suitable for the development of rail transportation.
