The application of RFID in transportation field

RFID technology with its accuracy, real-time, fast recognition features, has gradually become the main means of traffic information collection and regulation, the traditional traffic information collection technology, the impact is huge, believe that RFID technology will be the future trend of the development of intelligent transportation.Let’s look at the RFID technology in the application of traffic information collection and traffic control.

a, traffic information collection

the RFID technology in traffic information collection are mainly concentrated in the motor vehicle traffic information, road average speed, road congestion in these three aspects.

RFID can be set to collect for each lane of traffic flow data, accurately identify the vehicle type, fast traffic information, such as various nodes than traffic, lane occupancy, all kinds of car models, etc.

the RFID technology is also the average speed of every section of urban road test, to grasp the real-time road traffic situation of the city.

as for the test road congestion, RFID technology approach is to continuously read the same car the number of the RFID information (number) was far more than the normal driving and the poor to enter and leave the vehicle number of discriminant analysis, such as operation, can realize the single congestion, multiple lanes congestion or go slow and road congestion and so on the many kinds of road congestion.

2, traffic control

using the precise identification of the RFID technology acquisition techniques, we can to control traffic, mainly displays in the following aspects: traffic signals, buses and special vehicles, access management control in a particular area.
