基于GPS和IC卡数据的公交出行OD推算方法

OD Matrix Inference for Urban Public Transportation Trip Based on GPS and IC Card Data

主要基于GPS和公交IC卡数据研究推算交通小区公交出行OD的一种方法。将居民公交出行分为闭合型出行链和非连续型公交出行链,通过数据的挖掘融合技术,结合居民公交出行规律推算交通小区的公交OD矩阵,利用站点吸引强度对无明显规律的紊乱出行数据进行修正,提出了基于GPS和公交IC卡数据推算公交出行交通小区OD的方法,并以佛山市中心城区为例验证推算方法的可靠性。研究表明:所得公交出行OD矩阵精度较高。

A method for estimation public transportation traffic zone OD was developed based on GPS data and IC card data.Public transportation will be divided into a closed-trip chain and a non-continuous trip chain.On this basis,the estimation of public transportation traffic OD can be calculated by integrating data mining technology and community residential transit trip rules.The appeal strength of bus stop was used to revise the disorder trip data.A method was proposed to calculate public transportation traffic zone OD based on GPS data and IC card data,and the data of Foshan center city was cited as an example to verify the reliability of this calculation method.On the whole,this method has realized the estimation of high precision trip OD matrix and it can be applied to urban transportation planning and management.
