With the rapid development of my country’s national economy, urban construction is changing with each passing day, and urban traffic problems are becoming more and more serious, which has become one of the key issues that have seriously affected the development of many large and medium-sized cities. Many large and medium-sized city government departments invest a lot of manpower and material resources every year to improve and solve the problem of urban traffic congestion. The state has included the construction of intelligent transportation in the “Tenth Five-Year Plan” science and technology plan to provide key support. Many large and medium-sized cities are successively applying for the establishment of urban intelligent transportation demonstration bases. It is understood that the state has approved the first batch of 12 cities to establish such demonstration bases.

Compared with cars, urban public transportation has the advantages of large passenger traffic, relatively low investment, less resources, high efficiency, relatively low pollution, and less road occupation per capita. According to calculations by relevant experts: “The passenger capacity of public transportation in the city is 30 times that of cars, and it carries more than 80% of the city’s passenger capacity”; “If the road area occupied by conventional bus transportation is calculated as 1, then the same number of passengers will be transported. , The road area occupied by bicycles is 5, and that of cars is 15”; “According to the unit passenger capacity, its fuel consumption per kilometer, exhaust emissions and other indicators are about 10 times better than those of cars “. Therefore, in recent years, local government leaders and traffic management departments have gradually formed such consensuses: “Developing public transportation is a strategic choice for improving urban transportation” and “Solving urban transportation problems must reflect the principle of prioritizing the development of urban public transportation.”

The emergence of BRT can vigorously develop public transportation. With the help of digital and intelligent urban public transportation management, the efficiency of public transportation operation management and the level of social services have been improved. When a bus goes to an intersection and the green light turns to red, the smart bus signal priority system will extend the green light time appropriately to allow vehicles 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 24G RFID reader device independently developed by Baiersheng Electronics 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.

Install an RFID Reader that adjusts the signal light at 100-200 meters away from the intersection. When the bus approaches the intersection, the 2.4G active radio frequency card (Tag) on ​​the front of the bus responds to the card reader installed on the roadside. 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: Extend the green light in the direction of the dedicated lane, or shorten the red light.

At present, many cities in our country use traffic signal control systems to manage urban traffic, including systems such as SCOOT (UK), SCATS (Australia) and TRANSYT (USA). SCOOT and SCATS are adaptive traffic signal control systems (Traffic Adaptive Signal Control System); the United States adopts TRANSYT system is a non-adaptive traffic signal control system, when the city intersection adopts the advanced traffic signal control system, it reduces the driving delay time. Improve the traffic capacity of the intersection, reduce the number of vehicle parking, reduce fuel consumption and vehicle emissions of harmful substances.
