ATIS is based on perfect information network. Traffic participants provide real-time traffic information ATIS to the traffic information center through sensors and transmission equipment installed on roads, cars, transfer stations, parking lots and meteorological centers. After processing, they provide travel-related information such as road traffic information, bus traffic information, transfer information, traffic meteorological information and parking lot information to traffic participants in real time. According to this information, travelers determine their own travel modes and choose routes. Furthermore, when the car is equipped with an automatic positioning navigation system, the system can help the driver to automatically choose the driving route.
2. Advanced Traffic Management System (ATMS)
Some ATMS and ATIS*** use information collection, processing and transmission systems, but ATMS are mainly used by traffic managers to detect, control and manage highway traffic and provide communication between roads, vehicles and drivers. It will monitor the traffic conditions, traffic accidents, meteorological conditions and traffic environment in the road system in real time, obtain information about traffic conditions by means of advanced vehicle detection technology and computer information processing technology, and control traffic according to the collected information, such as signal lights, issuing guidance information, road control, accident handling and rescue.
3. Advanced public transport system (APTS)
The main purpose of APTS is to promote the development of public transportation by using various intelligent technologies, so that the public transportation system can achieve the goal of safety, convenience, economy and large capacity. For example, personal computers, closed-circuit television, etc. It is used to provide suggestions to the public on the choice of travel modes and events, routes and trains, and to provide real-time running information of vehicles to waiting people through the display of bus stops. In the bus management center, the departure and pick-up plans can be arranged reasonably according to the real-time state of vehicles, so as to improve work efficiency and service quality.
4. Advanced Vehicle Control System (AVCS)
The purpose of AVCS is to develop various technologies to help drivers control vehicles, so as to make them run safely and efficiently. AVCS includes autonomous driving technology, such as warning and helping drivers and avoiding obstacles. 5. The freight management system here refers to an intelligent logistics management system based on expressway network and information management system and managed by logistics theory. Comprehensive use of satellite positioning, geographic information system, logistics information and network technology can effectively organize cargo transportation and improve freight efficiency.
6. Electronic toll collection system
ETC is the most advanced road and bridge toll collection method in the world. The vehicle-mounted equipment installed on the windshield of the vehicle communicates with the microwave antenna on the ETC lane of the toll station in a short distance, and the computer networking technology is used for background settlement with the bank, so that the vehicle can pay the road and bridge fees without stopping at the road and bridge toll station, and the paid fees are distributed to the owners of relevant income after background processing. Installing an electronic toll collection system on the existing driveway can improve the lane capacity by 3~5 times.
7. Emergency rescue system (EMS)
EMS is a special system based on ATIS, ATMS and related rescue organizations and facilities. Through ATIS and ATMS, the traffic monitoring center and professional rescue agencies are integrated to provide road users with services such as emergency handling, traction, on-site rescue and troubleshooting of accident vehicles.
