With the rapid development of the national economy, the number of motor vehicles and road traffic flow has increased sharply, especially in large cities, where public transportation vehicles have increased, routes have been extended, and the number of vehicles has increased. The public systems in many cities in China still use manual dispatching methods, which leads to the slowdown of bus driving speeds and uneven driving intervals. Especially due to the lack of modern communication means, dispatchers cannot understand the operating vehicles and road conditions in real time. Using RFID in the rapid transit management system can realize automatic, accurate and long-distance collection of bus information, so that the bus dispatching system can accurately grasp the real-time dynamic information of the bus. Through the implementation of this system, the management level of buses can be effectively improved, the real-time traffic situation of the road can be grasped, the intelligent management of buses can be realized, and the image of the city can be improved.
Two system design:
(1) Topological structure diagram of the system
(2) The workflow and characteristics of the system
When the bus enters the parking lot, the electronic tag number placed on the vehicle is read by the remote reader. The reader automatically transmits the globally unique number or vehicle-related information that it reads to the background computer for processing. Record and process this information, record the arrival time of the vehicle, and transmit this information to the driver. The driver can know the information of other vehicles and adjust the speed of the vehicle.
System control equipment is installed at each light-controlled intersection along the BRT line. Some intersections are also equipped with special signal priority control and detection equipment for BRT. When the BRT vehicle reaches the intersection and the green light changes to red, the intelligent system The traffic system will appropriately extend the green light time to allow vehicles to pass smoothly. When the intersection is at a red light, the intelligent system will moderately shorten the red light time and reduce the waiting time of the rapid bus at the intersection.
