Road network traffic flow analytical method based on RFID technology

Abstract

The invention discloses a road network traffic flow analytical method based on an RFID technology. The method comprises the steps that firstly, RFID base stations are regarded as the travel end points of an OD matrix, an RFID base station network is built, and the basis of a dynamic OD matrix acquiring method based on the RFID technology is constructed; secondly, the time collection degree is selected according to application requirements, vehicle data collected by the RFID base stations are converted into vehicle data of vehicles which pass through any two RFID base stations and have the same license plate number, the license plate numbers of the vehicles and the moments of the vehicles passing through the two RFID base stations are obtained, the time sequences of the vehicles passing through the two RFID base stations are compared, the original destinations of the vehicles are determined, and the traffic volume of the traffic flow with the two RFID base stations as the travel end points is obtained through statistics; finally, the acquired traffic volume between any two RFID base stations is organized to be in the mode of the OD matrix.

Description

technical field [0001] The invention relates to a dynamic OD matrix acquisition method based on RFID technology, belonging to the field of intelligent traffic systems in traffic engineering. Background technique [0002] With the acceleration of the process of urban-rural integration in our country, the scale of cities in various places is constantly expanding, and the traffic problems are becoming more and more serious and affect the normal operation of the city's theme functions. Facing the extremely complex urban road network system, it is difficult to fundamentally solve the traffic problem simply by expanding the urban road infrastructure. In this context, researchers from various countries have turned their research focus to intelligent transportation systems. The development of intelligent transportation system originated in developed countries such as Europe, America and Japan. It is the development direction of the future transportation system. It is the effective ...
