Research On The Planning Of Public Transit Transfer Hub On-street

Recently,with an increasing residents’ demands for public transit,the lagging urban public transit hub system let optimizing transit network and upgrading bus service level be the difficulties.Due to above-mentioned issues resulted from land-use intensification,planners cannot allocate enough indemnificatory land for the construction of public transit.From macro-and micro-standpoints,the public transit transfer hub on-street is studied respectively to release the contradiction between intensive land-use and the growing demands for public transit in urban areas.Based on summarizing relevant characteristics of the public transit transfer hub onstreet,it is indicated that macro-and micro-factors of setting,goals,methods,and keys of public transit transfer hub on-street.The keys of setting public transit transfer hub onstreet are different from the traditional public transit hub.Principal study concentrates on establishing an integral model covering macroscopic locating model and micro-model of berth matching.On the macroperspective,locating model of public transit transfer hub on-street is based on the minimal total passenger cost function.On the micro-perspective,berth matching is supported by queuing theory.Locating model with berth matching is integrated by some parameters,such us delay,comfortableness,waiting time and so on.Finally,according to the present and future demands for public transit network of Gongming,Shenzhen,the location of public transit transfer hub on-street is calculated by integral model respectively.Compared various parameters,it is indicated that public transit transfer hub on-street could increase public transport split rate with a decreasing total generalized cost simultaneously.Besides,it is also a passenger flow collectordistributor point that attracting tremendous transfer passengers.
