Application of RFID in Traffic Field_ Taigewang Technology

With its accurate, real-time and fast identification characteristics, RFID technology has gradually become the main means of traffic information collection and supervision. For the traditional traffic information collection technology, its impact is huge. It is believed that RFID technology will become the development trend of intelligent transportation in the future. Let's take a look at the application of RFID technology in traffic information collection and traffic control. 1、 Traffic information collection RFID technology in the collection of traffic information mainly focuses on three aspects: vehicle flow information, average road speed and road congestion. RFID can set collection points to obtain traffic flow data of each lane, accurately identify vehicle types, and quickly obtain traffic flow information, such as traffic flow at each node, lane occupancy, various vehicle model ratios, etc. RFID technology can also test the average speed of roads in various sections of the city to master the real-time traffic situation of roads in the city. As for the detection of road congestion, the method adopted by RFID technology is to continuously read the RFID information of the same vehicle (far more than the value of normal driving) and analyze and calculate the difference between the number of entering and leaving vehicles, which can detect a variety of road congestion conditions such as single lane congestion, multi Lane congestion or slow traffic and road section congestion. 2、 Traffic control through the accurate identification and acquisition technology of RFID technology, we can control the traffic, mainly in the following aspects: traffic signal, bus and special vehicle signal, access management in specific areas, etc.
