Just after the National Day holiday in Eleventh, the students had already returned to the school and the working class returned to their jobs. The small hawkers who “gold rushed†in the city also reopened their stalls. However, the three major traffic accidents that occurred on the last day of the 11th holiday have cast a dark shadow on this holiday. On October 7, three accidents in Henan, Anhui, and Tianjin caused 56 deaths. Among them, 35 people in the Binbao high-speed car accident were killed and 18 injured. Among them, many returned to Hebei as college students. The long-standing topic of traffic safety has once again been pushed to the Chinese people in its usual form of tragedy.
When a major traffic accident occurred on a passenger car on the “Beijing-Zhuhai Expressway†this year, the Ministry of Communications immediately issued a “Circular on Strengthening the Dynamic Supervision of Road Transport Vehicles†issued jointly by the three departments, requiring that all passenger vehicles in the country must be loaded with a GPS positioning system. And on-board video surveillance system to ensure that it can minimize the occurrence of traffic accidents. Just after the "Notice" just issued three major traffic accidents in more than two months, we have to rethink the road to traffic safety monitoring. What measures must be taken to prevent the occurrence of major traffic accidents? Where do we need to improve in air defense and technical defense?
From the “Beijing-Zhuhai Expressway†accident to the occurrence of these three traffic accidents, there are subjective and objective factors. From a subjective point of view, the most important is that fatigue driving leads to inconsistency and causes rear-end, and the objective factor is more about the impact of the external environment. To avoid the occurrence of traffic accidents, the driver must first be familiar with the traffic regulations and follow the traffic rules on a subjective level. Concentrate attention during the driving process to avoid drunk driving, fatigue driving, speeding, and careful driving. Factors in this area are within the control of people.
Apart from subjective factors, more often there are many unexpected situations in the driving process that are not controlled by the people. This requires the use of monitoring equipment to grasp the traffic information. From this perspective, it is extremely important to increase the construction of the traffic monitoring system. From the accidents that occurred in succession, the traffic accidents that cause heavy casualties are often on the expressway. The main reason is that the vehicles are often unprepared when they encounter unexpected situations during high-speed driving. Ability to control the vehicle's driving route. Prior to this, the Ministry of Communications issued a notice to passenger vehicles that the vehicle must be loaded with a GPS positioning system and an on-board video surveillance system. This measure is more targeted. The GPS positioning system enables the monitoring center to monitor the speed and direction of the vehicle at any time, recording the vehicle's exit time, parking time, running route, and driving mileage. When an abnormal situation occurs during the running of the vehicle, the monitoring center can timely obtain information and warn the vehicle. The video surveillance system transmits the video images collected by the front-end camera to the nearest GPRS and 3G wireless networks. The monitoring center can observe the internal conditions of the vehicle at any time. The main object to be rectified in the "Notice" is the passenger bus operated by the passenger transport company. In the three accidents that occurred this time, the rear-end accident on the Binbao expressway was the school bus, and the accident occurred. Whether or not a vehicle has an onboard video surveillance system is still unknown. However, it cannot be ignored that many schools and enterprises and institutions currently have their own passenger transport vehicles and this number is not a minority. However, these vehicles are not included in the "Notice" to be subject to mandatory rectification. This has also caused many unstable factors. Buses, schools, enterprises, institutions, and government agencies should also carry out compulsory rectification. This is especially important for school vehicles.
In recent years, many cities have been making great efforts to develop intelligent transportation. Some cities have begun to try to apply an emerging technology to the construction of intelligent transportation. This is the vehicle-mounted IoT technology. In essence, automotive IoT is actually a huge wireless sensor network. Every car can be considered a super sensor node. Usually a car is equipped with internal and external thermometers, brightness sensors, one or more cameras, microphones, ultrasonic radars, and many other equipment. In addition, the car will also be equipped with a vehicle computer, GPS locator and wireless transceiver. This enables wireless communication between cars, as well as between cars and roadside base stations. This means that even when driving in heavy fog, cars can clearly understand their surroundings through the wireless sensor network. If their vehicles are in a dangerous driving area, they can adjust their driving routes in time. Make sure you can drive in the safest area. The current road monitoring facilities in China are traffic cameras installed at major road intersections, speeding cameras on expressways, and RFID readers installed on freeway toll gates. However, its role in the occurrence of traffic safety accidents is not obvious. If the vehicle-mounted IoT can be widely used in road safety monitoring, it will inevitably greatly increase the safety and efficiency of the traffic system.
