METHOD FOR ESTIMATING SECTION FREIGHT TRAFFIC VOLUME IN RAILROAD TRUNK LINE SECTION

摘要

PROBLEM TO BE SOLVED: To provide a method for estimating section freight traffic volume in a railroad trunk line section which can simply estimate the section freight traffic volume in the trunk line section accompanying a change of a traffic condition and an increase and decrease of freight stations in a railroad freight traffic network.;SOLUTION: In the method for estimating the section freight traffic volume in the railroad trunk line section, an estimation of the section traffic volume is carried out based on adjustment of a database of freight traffic passing through the trunk line section and a conversion of traffic volume data. In this estimation of the section traffic volume, all route numbers y_ij are counted for each OD(ij), route numbers x_ij passing a target section are counted for each OD(ij), traffic volume q_ij for each OD is multiplied by a ratio (x_ij/y_ij) of the route number to find by-OD section traffic volume f_ij=(x_ij/y_ij)q_ij, and f_ij is added concerning all the ODs to obtain section traffic volume F.;COPYRIGHT: (C)2012,JPO&INPIT
