Study On The Layout Of Highway Passenger Transport Hub Function Area

As a significant node in the highway transport network,the highway passenger transport hub is an important place for realizing the "seamless convergence" between the various modes of transportation and providing "zero distance" transfer service for the passengers.At present,the layout of the functional area of the hub is unreasonable,the passenger streamer is not smooth,and the effective connection between the modes of transportation can not be realized.The passenger transfer is inconvenient and the overall transfer efficiency of the hub is low.The effective layout of each function area in function and space is the prerequisite to realize the function of the hub.The reasonable layout mode can realize the effective connection between the modes of transportation,and provide convenient service for the passengers,so as to improve the overall transfer efficiency of the hub.In view of this,this paper chooses the layout of the functional area of highway passenger transport hub.Begin with the basic theory of highway passenger transport hub,this paper analyzes the concept,attribute,function and development trend of highway passenger transport hub,and divides the functional area of highway passenger transport hub.Then,it adopts the method of transfer quantity forecasting which based on double constrained gravity model and analyzes the scale of the various functional areas in the hub,and then analyzes the layout pattern and layout influencing factors of the functional area of the highway passenger transport hub.This paper constructs the model of the functional area layout which takes the shortest distance of passengers in the highway passenger transport hub as a goal and puts the scale,shape and position of the functional area as the constraint and uses the Matlab as the platform to adopt the genetic algorithm to carry on the functional area layout model solution.Finally,the functional area layout model is used to solve the problem.The model is applied to the example,and the layout scheme of the functional area is obtained,which provides some reference for the planning and design of future highway passenger transport hub.
