In recent years, with the rapid economic growth and the rapid increase in car ownership, traffic congestion and frequent traffic accidents have caused more and more huge waste of time, property losses, and environmental pollution. Traffic problems have become a problem, including in our country. One of the important problems faced by governments all over the world. Data shows that the average driving speed of most cities in my country has dropped below 20km/h, and in some cases it is even only 7~8km/h. At the same time, due to slow vehicle speeds and increased exhaust emissions, the air quality in cities has further deteriorated. . In order to alleviate the pressure of economic development on transportation and maximize existing assets, the Chinese government has increased the research and construction of intelligent transportation systems.
Intelligent transportation is the effective comprehensive application of information, communication, control, computer network and other high-tech ground transportation management systems, thereby establishing a large-scale, all-round function, real-time, accurate, and efficient transportation management system. It is currently the leading research topic in the field of transportation in the world, and it is also the best way to solve urban traffic congestion, improve driving safety, increase operating efficiency, and reduce air pollution. It is foreseeable that the intelligent transportation system will become the mode and development direction of the modern ground transportation system in the 21st century, and an important sign that transportation has entered the information age.
Introduction to Intelligent Transportation System
The system is a real-time, accurate and efficient comprehensive traffic management system established by organically applying advanced RFID technology, GPS technology, cloud technology, mobile communication technology, automatic control technology, and computer network technology to the entire traffic management system. And control system. It is composed of several subsystems (such as free-flow detection system, non-stop toll system, rapid transit system, signal control system, information release system, etc.) through system integration to organically combine roads, vehicles, and pedestrians to strengthen the three Real-time, accurate and efficient monitoring of traffic conditions.
Intelligent traffic management system function
. Real-time positioning function, to make up for the unstable signal of GPS satellite positioning and many blind areas in the city. The identification device installed in the known location can identify the vehicle tag to realize the tracking and positioning of the vehicle;
. Non-stop toll collection, this function has been implemented on many expressways;
. Intelligent signal light control, through vehicle type identification and right-of-way analysis, to achieve automatic traffic signal control, such as bus priority;
. Access control, through the reader installed on the bayonet, in conjunction with other automatic control systems, it is possible to prevent vehicles that do not meet the requirements from entering a certain area, such as airport parking management;
. Traffic statistics, combined with the vehicle systems passing through a certain road section, real-time release of parking space information in the parking lot, and provide parking guidance for traveling vehicles;
. Publish bus arrival information, congestion, road condition information, warning information, toll records, etc. through on-board display, language broadcasting system, outdoor variable information board, broadcasting technology, network technology and other means;
. License plate anti-counterfeiting, use the detailed vehicle information recorded in the label to determine the legitimacy of the vehicle and prevent cloning of vehicles.
Benefits of Intelligent Traffic Management System
. Improve the overall management level of the city, the efficiency of people’s travel and the level of public services;
. Reduce road land, improve land utilization and utilization level, and expand road capacity;
. Save money and maintain the overall management level of the city, the efficiency of people’s travel and the level of public services;
. Establish a good image of the city, enable the full development of tourism resources, and indirectly bring huge economic benefits to the city;
. Improve the city’s investment environment and enhance the city’s international competitiveness;
. Save energy, protect the environment, maintain sustainable social and economic development and harmonize with the environment.
