Research On Attraction District Of Intercity Railroad Based On Corridor

The inter-city railway attract district is an important basis for the inter-city railway's construction planning, it help the inter-city railway layout and prevent uneven or excessive waste of resources and the set of sparse uneven because the market is estimated.The inter-city railway attract district in the corride is fuzzy and hard to certainty,which not noly affect the feasibility of inter-city railway construction decisions,but also affected the openrating parameters of the inter-city trains have been completed.This article is based on previous studies and further analysis of the district of inter-city rail passenger attraction, and it try to establish a rational theory of system and programming method for its reflection.In the article, Characteristics to transportation attract, attract the range of principles and classification and other related theories are described. First, the functional inter-city rail position, combined with metropolitan and urban group spatial scales to inter-city rail service area defined in the Urban Space Group 50km-400km range.Second,the, the inter-city railway's attraction district is divided into two-stage.To serve as a carrier within the transport corridor, the ariticle analysis inter-city rail hub's attract effect and the line's aggregation or spread forms to demonstrate the primary attractive district mainly in the hun (site) surrounding area. From the residents take the Intercity rail travel in the whole process, considering the city's transportation, transfer points, and regional conditions and the reachability's impaction to primary attractive, The hub (site) as the center of the feeder layer by travel district, the use of intercity rail connection mode selection Ends travel where the economy even as a particle attracted by a range.Then, studying the path in the entire network, the ariticle define the secondary attraction district of city's spindle system'scope and inter-city commuter rail system of the scope. Standing residents travel mode choice of the point of view of traffic channel features a variety of transportation modes, the establishment of an integrated utility function of travel choice and draw two attractive range of comparative analysis, the final scope of the two superimposed been attracting inter-city rail All the attraction.Finally, as the Suiyu inter-city railway in the Chengdu and Chongqing in comprehensive corridor an example verify the results of the study.
