Contents of intelligent electronic transportation system: North America, Northern Europe and South Korea have their own focuses on the research of intelligent electronic public transportation system. Although the United States started later than Northern Europe and South Korea, from the perspective of the research field and content of electronic intelligent public transportation, the United States has a wider research field and richer research content. Before October 1995, the research content of IWHS in the United States mainly focused on advanced traffic management systems, advanced traveler information systems, advanced public transportation systems, and commercial vehicle operation systems. At present, the ITS research in the United States is concentrated in 7 fields with a total of 29 research contents. In 1998, the US Department of Transportation determined that there were 311 research projects for electronic intelligent transportation systems. The following mainly introduces the research contents of ITS in 7 fields. If these contents are applied to the public transportation field in China, they will play an important role in the informatization, intelligence, safety and convenience of public transportation . 1 Travel and transportation management system This system includes 6 main contents: ① Traveler service information system. This system can provide fast services for travelers, such as the location of travelers to their destination, working hours, food supply, parking conditions, vehicle repair stations, hospitals and traffic police offices. ② Route guidance system. It provides travelers with the best driving route to their destination. ③ Traffic control system. Provide an adaptive intelligent control system for highways and urban roads to improve traffic flow conditions and provide priority for public transportation vehicles to alleviate traffic congestion problems for all motor vehicles. ④ Traffic incident management system. Help public and private institutions quickly identify and respond to emergencies to minimize the impact of emergencies on traffic. ⑤ Vehicle emission detection and control system. The system uses advanced vehicle emission detection equipment to monitor air quality and adopts a series of measures to control pollution. ⑥ Online driver information system. The system includes a driver guidance system and an in-car sign system. 2 Travel demand management system 2.1 Pre-trip information system. Pre-trip information refers to the real-time travel information obtained by travelers at home, work and other places before departure, such as public transportation routes, timetables, transfers and fares, as well as information on long-distance travel between cities and vacation travel, as well as real-time traffic accident information, route changes and route driving speed information. 2.2 Carpooling information system. This system can very conveniently provide carpooling information, which can reduce the traffic flow of small passenger cars, ease traffic congestion and reduce the occurrence of traffic accidents. This is not only beneficial to people traveling for work, but also provides great convenience for the elderly and the disabled. 2.3 Demand management and operation. This study reduces the number of individuals driving alone to work by formulating transportation demand management and control policies, encourages people to make more use of high-occupancy vehicles and public transportation, and provides more alternative travel modes for people who want to improve travel efficiency. 3 Public Transportation Management System 3.1 Public Transportation Management. In order to improve public transportation management, it mainly uses computer technology to conduct real-time analysis of the technical status and service level of vehicles and facilities, and realize the automation of public transportation system operation, planning and management functions. 3.2 Transfer information on the way. This study can provide real-time and accurate transfer and transfer information for travelers using public transportation, helping travelers make timely transfer decisions and adjust travel plans as needed on the way. 3.3 Individual public transportation. This type of public transportation can meet the public transportation needs of individuals for non-fixed or quasi-fixed lines, and provide very convenient services for passengers. 3.4 Public transportation safety. It provides a safe transportation environment for public transportation passengers and drivers. 4 Electronic toll collection system The electronic toll collection system provides a universal electronic payment method for users to pay tolls, ticket fees, parking fees, etc. At present, China only uses IC cards to pay tickets. In the future, it will gradually realize one-card payment, and use this card to realize one-card payment for public transportation such as buses, taxis, and urban railways. At the same time, through network information, the automation of charging and payment is realized, thereby promoting the development of multimodal transportation.

5. Operational systems for commercial vehicles 1) Electronic
clearance system for commercial vehicles . This system requires trucks and buses to be equipped with radio receivers to determine the speed and load weight of vehicles on major routes to ensure the safety of vehicles. 2) Automated roadside safety inspection system. This system provides a real-time safety inspection channel for vehicles and drivers, and it can determine which vehicles should stop for inspection. 3) On-board safety monitoring system. This system can automatically monitor the safety of commercial vehicles, cargo and drivers. 4) Administrative management system for commercial vehicles. This system uses electronic means to handle registration procedures, automatically record mileage, fuel consumption reports and check accounts. 5) Commercial fleet management system. This system can establish communication links for drivers, dispatchers and multimodal transport managers, use real-time information to determine the location of vehicles, and facilitate vehicles to travel on non-congested roads. 6) Dangerous goods emergency response system. This system can provide law enforcement officers with timely and accurate information on the types of dangerous goods, so that they can make appropriate handling in emergency situations, thereby controlling risks and avoiding accidents. 6. Emergency management system 1) Emergency notification and personal safety. This part includes two functions: one is to ensure the safety of drivers and other personnel, and the other is that the automatic notification system will automatically brake the vehicle and notify the rescue agency after a dangerous accident occurs. 2) Emergency vehicle management. This type of vehicle management must first have a public safety agency, which establishes direct communication with the fleet management department. 7 Advanced Traffic Control and safety system 1) Avoid longitudinal collisions. The main purpose of this service system is to reduce head-to-head collisions between vehicles and collisions between vehicles and people and objects. 2) Avoid lateral collisions. In order to prevent vehicles from leaving the road and causing collisions between vehicles and objects, the monitor set up by the system can observe places that the driver cannot see and warn the driver to avoid impending collisions. 3) Avoid collisions at intersections. This system can warn the driver to avoid collisions when approaching and crossing intersections, and remind the driver to drive carefully when the right of way at the intersection is unclear. 4) Expand vision to prevent collisions. Improve the driver's field of vision to avoid potential collisions. The system can also help the driver comply with traffic signs and signals. 5) Precautions before collisions. In order to ensure the safety of passengers, some measures should be taken in advance to prevent casualties in the event of an unavoidable collision. 6) Safety forecast system. This system can forecast the driver, vehicle, and road conditions. For example, the monitor installed in the car can warn the driver to pay attention to driving safety when he or she is drowsy. 7) Automated highway system. This system can provide a fully automated operating environment, which is actually creating an electronic intelligent transportation system. The electronic intelligent transportation system is at the forefront of research in the field of transportation. It is a comprehensive application of real-time traffic information theory and new technologies. Therefore, new problems will continue to emerge. After several years of research and gradual application of the content projects of the electronic intelligent transportation system, I believe we will reach and realize the goal of safe, convenient, and comfortable one-hour urban economical public transportation.
