system introduction
With the help of digital and intelligent urban public transportation management, BRT has improved the efficiency of public transportation operation and management and the level of social services. When the green light turns to red when the bus is driving to the intersection, the intelligent bus signal priority system will extend the green light time to allow the vehicle to pass smoothly; and when the intersection is red, the intelligent system will moderately shorten the red light time. Reduce the waiting time of buses at intersections; thereby partially solving and improving a series of public transportation problems caused by urban traffic congestion.
The long-distance RFID reader device independently developed by Ningbo Zhongke can effectively help the intelligent bus signal priority system. This system has high technical content. Through automatic identification of long-distance moving vehicles and non-contact information collection and processing, advanced information technology, data communication technology, electronic control technology and computer processing technology are effectively integrated into the ground transportation management system , So as to establish a large-scale, all-round function, and real-time, accurate, and efficient traffic management system. Realize the purpose of giving priority to public transport signals.
How the system works
Install a card reader (RFID Reader) that adjusts the signal light at 100-200 meters away from the intersection. When the bus approaches the intersection, the active radio frequency card (Tag) at the front of the bus responds to the card reader installed on the side of the road. The card reader signal is connected with the traffic signal control system of the traffic command center, and the signal lights at the intersection will change: The green light in the direction of the road is extended, or the red light is shortened.

System physical structure and composition
RFID reader
It is composed of information collection, processing, information transmission, explosion-proof power supply, and embedded software.
Its main function is to complete the real-time collection and processing of the output signal of the vehicle identification code, and be responsible for two-way communication with adjacent base stations or terminal equipment.
RFID radio frequency card
It is composed of an embedded processor and its software, a transmitting and receiving antenna in the card, a transceiver circuit and a high-energy battery.
Function: The special number is pre-stored in the microcontroller, and the unique encrypted identification code radio signal is transmitted intermittently. The high-energy battery in the card provides energy for the normal operation of the identification card, and the battery in the card can be replaced.
Intelligent traffic control system
Currently the United States uses the TRANSYT system, the United Kingdom uses the SCOOT system, and Australia uses the SCATS system to achieve this control.
