A method for defining the scope of passenger flow attraction at rail stations based on arcgis

Abstract

The invention discloses an ARCGIS-based rail transit station passenger flow attraction range defining method. The method includes calculating travelling speeds of different trip modes, the average travel distance of urban residents and transfer time between rail transit and other modes, and determining a direction attraction range, an indirect attraction range and a potential passenger flow attraction range; acquiring an irregular polygon by taking the trip modes, trip paths and trip time as constraint conditions for the direct attraction range and the indirection attraction range and introducingThiessen polygon in meteorology for division of a transit station potential attraction range; constructing a road network set by utilizing a geological information system and creating a passenger flow attraction zone by using reasonable distances between different attraction zones as a resistance factor; and introducing rail transit stations and solving the attraction ranges of the stations according to an enclosure rule of attraction range. By employing ARCGIS software and taking the trip modes, trip paths and trip time as constraint conditions, rail transit station passenger flow attraction ranges are determined accurately and rail transit passenger flow predication accuracy is ensured.

Description

technical field [0001] The invention relates to an ARCGIS-based method for defining the range of passenger flow attraction at rail stations. Background technique [0002] Reasonably defining the scope of station passenger flow attraction is the basis for carrying out research on rail station passenger flow prediction, connection mode division, and traffic facility scale prediction and layout. The methods currently used in China are mostly fixed-value geometric methods. After determining the attraction distance, regular circles or squares are used to determine the passenger flow attraction range of the site. In the calculation of passenger flow, repeated calculations or missing data are prone to occur, which reduces the accuracy of passenger flow forecasting. .
