A method for estimating OD Matrix of Urban Road Network using RFID and Analysisof its Spatio-temporal Features
摘要
Abstract
In order to meet data requirement of modern urban traffic management systems,an acquisition technique for origin-destination (OD)matrix based on the radio frequency identification technology (RFID)is proposed.This paper takes RFID base stations installed along urban road network as origins and destinations,license plate data collected at ori-gins and destinations through RFID is matched using a set of data mining techniques,under different aggregate time reso-lutions.Based on this technique,a sample of road network extracted from City of Nanjing is selected as the case study,its OD data is collected,OD matrix is developed and its spatio-temporal features are analyzed.Empirical results show that the proposed technique is able to obtain the OD matrix under any aggregate time resolution,and the spatio-temporal fea-tures of the obtained matrices are consistent with observed traffic conditions.The proposed technique shows an excellent timeliness and operability,providing an important data tool for urban transportation management.关键词
