Road traffic flow detection method and system based on RFID (Radio Frequency Identification)

Abstract

The invention relates to a road traffic flow detection method based on RFID (Radio Frequency Identification). The road traffic flow detection method is characterized by comprising the following steps of: firstly arranging a passive vehicle-mounted RFID label on each vehicle, secondly providing an RFID label reader at a road section to be detected, reading and counting road traffic flow by the RFID label reader when a vehicle with the passive vehicle-mounted RFID label enters an effective reading range of the reader, and transmitting statistic information at every time T through wireless network to a remote monitoring center. According to the road traffic flow detection method based on the RFID, disclosed by the invention, dynamic real-time detection of the road traffic flow can be realized by utilizing an RFID technology and can be also realized by a radio frequency card reader without carrying out any changes on road base installation; and in addition, radio frequency labels can conveniently record information of vehicles, and intelligentized management can be expansively implemented when traffic flow is detected.

Description

technical field [0001] The invention relates to the field of road traffic flow detection, in particular to a road traffic flow detection method and system based on radio frequency identification. Background technique [0002] With the city's economic development and increasingly busy social activities, urban traffic has experienced unprecedented rapid growth, and traditional road traffic facilities can no longer meet the needs of modern society. At present, the traffic problems in cities, especially big cities, are extremely serious. If they cannot be effectively solved and fundamentally treated, they will definitely pose a serious threat to the sustained, rapid and healthy development of the economy. [0003] Intelligent Transportation System (Intelligent Transportation System, ITS) is one of the hottest and most important topics discussed and researched in the field of transportation at home and abroad in recent years. It is the integration of advanced information technolo...
