Research On The Setting Of Bus Hub Station In Clustered Mountain Cities

The priority development of public transport and realize integration of publictransportation is one of the effective ways to solve the traffic problems in the city. Atpresent, many of the big city in our country has put the priority development of publictransport on an important position, but with the rapid development of publictransportation, all kinds of problems are highlighted, for example, part of city absencethe public transport hub station，a lot of city insufficient attention to the planning ofpublic transport hub station、the layout of public transport hub station is not reasonable、the internal settings of public transport hub station is not scientific, these problems ledto the bus lines repeated、the phenomenon of bus queuing and the bus congestion inpublic transport hub station occur from time to time, it not only increase the buspassenger travel time but also reduce the city public transport efficiency, these problemsare particularly prominent in clustered mountain cities.So it is very necessary toresearch on the setting of bus hub station in clustered mountain cities.The thesis firstly expound the definition of clustered mountain cities and it’s cityspatial structure、 land use layout、 city road network characteristics,through thecomparative analysis of clustered mountain cities and plain cities resident trip rate、tripmode、trip time consumption、trip time and space distribution, summarize the residenttrip characteristics of clustered mountain cities; Secondly, given the conventional bushub station definition、function and classification, analysis the characteristics of the bussystem in clustered mountain cities,and use of transportation planning four stage methodmake a prediction of bus passenger demand for clustered mountain cities, puts forwardthe vehicle configuration scale model and conventional bus hub station land demandmodel; Thirdly according to the target、principle and influence factors of the setting bushub station in clustered mountain cities，proposed the layout mode which suitable forbus hub station in clustered mountain cities and make a macroscopic layout of bus hubstation, proposed the address choose collection of bus hub station which be satisfiedwith the demand of node connectivity、passenger distribution、 network topology、node accessibility,using a comprehensive evaluation method (combined withmathematical average method based on the function and mathematical variance methodbased on the main difference) calculation node important degree to determine thealternative site bus hub station, overall consideration the passenger freight and the constructioncost minimization of bus hub station,use of the discrete and supersede model to determine the final address of public transport hub station in the address of the candidate. Finally,according to the traffic organization given a internal settings advice of public transit hubstation in clustered mountain cities.The thesis takes setting the public transit hub station of Chongqing urban areas asan example, analyzes the macroscopic and microscopic process of setting the bus hubstation, it proves that the method is scientific and feasible.
