Xiamen 324 State Road Pilot Traffic Safety Engineering

With the rapid economic development of Xiamen City, the scale of villages and towns along the Xiamen section of the 324 national highway has continued to expand, and industrial parks have developed rapidly. Safety facilities on the road surface of the 324 countries have been unable to meet the rapid growth of motor vehicles, and traffic accidents have occurred from time to time. In order to improve this situation, the market has assigned to launch the pilot project of road traffic safety prevention and control on the 324 national highway, and it was put into operation on December 30 last year. The pilot project has a full sense of science and technology, and the number of traffic accidents after the start of use has dropped by nearly 30% year-on-year, providing a strong guarantee for the traffic safety of the 324 National Road.

The gate warning system senses that the village road exits the vehicle and turns on the strobe light reminder

Along the 324 National Road, there are many roads along the village roads. When the vehicles on the national road run at a high speed, the vehicles on the village road are suddenly pulled out. The car owners may inadvertently take a tragic car accident.

On the 324 State Road, Xiangan Liantang Village exit, there is a warning sign. The sign reads "There is a dangerous car" in four characters. A blue box and a strobe light are installed on the top. Suddenly, the strobe lights began to flash, and after 5 seconds, a small truck was taken from the intersection into the national road.

Liao Wuqiang, head of the Dao Group of the Municipal Commission, said that this is a warning system for flood control. Solar energy is used to provide energy. As long as there is a car 50 meters away from the entrance of the village, the system will automatically sense and open the strobe lights to remind the passing vehicles to pay attention. . It is understood that the City Road Safety Office has set up vehicle warning equipment at the intersections of poor sightlines in 18 villages along the 324 National Road.

Meteorological forecast warning equipment real-time monitoring of wind speed rainfall according to the actual adjustment of speed limit

When driving on the road on cloudy or rainy days, the roadside electronic display will show the words “Slippery on the rain, please slow down”, but there are not many owners who slow down slowly. If the speed limit value can be automatically adjusted according to the weather conditions, traffic accidents will be reduced. Therefore, weather forecast warning equipment came into being.

State Highway 324 Liantang section speed limit of 70 kilometers, but in the morning, the reporter saw the speed limit card on the site to display 60 kilometers. Liao Wuqiang said that due to the gloomy weather and low visibility, weather forecast warning equipment will automatically adjust the speed limit to 60 kilometers. The equipment includes a windmill-like spinning top and an oval rainwater collection tank. “The equipment monitors wind speed rainfall in real time. When the wind speed or rainfall reaches the set limit, the equipment will automatically display the current limit speed on the display board according to the set speed value, and use the newly established 3 variable information board release limit at the key intersection. The speed value reminds the driver to slow down. "It is understood that the use of this equipment is still the first time in the province's national road.

Deceleration vibratory markings increase friction between the tire and the ground, and the vehicle acts as a cushion for downhill

From the downhill slope of Huangshan Road to Inner Mongolian Center in Xiang'an, due to topographical conditions, it was a traffic accident-prone area. Nowadays, the market has assigned a horizontal deceleration vibratory marking on the ramp to increase the friction between the vehicle's tires and the ground, which acts as a buffer when the vehicle is downhill, and prevents the vehicle from overturning or overturning into the opposite lane.

It is understood that the deceleration vibratory marking line has a total of 20 points in the 324 State Road, a total of 3240 square meters. A total of 1800 square meters of roadside vibratory markings at 15 points are set at places where the road is curved or where there is a continuous turn. Reflective spikes are also provided on the marked lines to prompt the direction of travel of the road when the vehicle turns and prompt reminders. The owner corrects the direction.

Video surveillance equipment discovers traffic jams in a timely manner

Liao Wuqiang introduced that the 324 National Highway Xiamen section had newly built 56 sets of monitoring equipment, adopting a combination of high and low methods, and at the same time using the established video resources to provide three-dimensional seamless coverage of key road sections and intersections (especially accident-prone road sections) to achieve video patrols and accidents. Remote processing quickly. The equipment can not only detect traffic jams, accidents, facilities, and road conditions in a timely manner, but also automatically alarm the traffic jams. It can also save the police power, detect problems in a timely manner and send out police to achieve intensive patrols at key points and time periods.

Because there are many cities and towns on both sides of the 324 National Road, the vehicles on the road are relatively intensive, and video surveillance with full coverage can also remotely collect evidence of minor accidents such as friction and collisions, and quickly handle accidents remotely to reduce congestion caused by accidents.

Illegal behavior capture device automatically detects over-limit overload and timely warning speeding vehicle

It is understood that the construction of this system will also include the addition of two sets of signal control systems at key intersections to resolve the conflict of traffic and traffic chaos in all directions at intersections and regulate the order of traffic at intersections.

At the junction of Zhangzhou and Xiamen on the 324 National Highway and the junction of Quanzhou and Xiamen, there are two sets of automatic snapping equipment for violations. The system is installed on the road section and uses digital detection technology and camera technology to detect the parameters such as total vehicle weight, vehicle speed, number of axles, axle load, direction, and alarm signal of overload (limit), and then refer to the “Outline” of the road vehicle. Load Quality Limits to determine whether the vehicle is overloaded.

The 324 national highway spans four districts outside the island. In addition to the Haishu District where the equipment has been built, a total of 10 sets of speed-measuring equipment have been built in the Xiang'an, Tongan, and Jimei districts to automatically capture and speed-up the speeding vehicles. The warning not only avoids the traffic accident caused by the speeding of the vehicle, but also technically solves the easy evasion of single-point speed measurement, and realizes full speed coverage of the accident hidden road section. A total of 29 sets of red light detection equipment were installed at intersections where signal lights were controlled, and the phenomenon of accidents caused by vehicle red lights was checked.

Effectiveness: The death toll dropped by 40% in property loss

At present, the mileage of roads in Xiamen is more than 4,000 kilometers, and the length of the 324 State Road in Xiamen is 54 kilometers, which only accounts for 1.39 percent of the city's road mileage. However, road traffic accidents have exceeded the proportion of road mileage. Last year, 279 state road accidents caused 279 road traffic accidents, 32 deaths, 328 injuries, and 534,503 yuan in property losses, which accounted for 26.22% of the city's 2014 accidents, deaths, injuries, and property losses, respectively, 26.02%, 21.05%, and 27.94. %, 22.84%. The accidents occurred in heavy-duty trucks and motorcycles. The accidents of the two types of vehicles accounted for 93% of the total accidents on the road.

Since the pilot project of the 324 national road traffic safety prevention and control pilot project has achieved remarkable results. From January 1 to March 3 this year, a total of 19,794 legal violations such as red lights, illegal lane changes, 4,652 illegal speed violations, and 2,343 violations were imposed. The accident situation on the road section dropped as a whole. According to statistics from the traffic police department, within two months, there were 26 road accidents involving 324 national highways, 6 people were killed, 29 were injured and property losses were 14,755 yuan. Compared with the same period of last year, the number of accidents dropped by 27.78%, and the death toll decreased. 45.45%, the number of injured persons dropped by 48.21%, and property loss decreased by 84.31%.

With the successful completion and successful application of the 324 national highway traffic safety prevention and control pilot project, Xiamen City will continue to promote the trunk road network, including the upgrade and reconstruction of national and provincial road safety prevention and control, and speed up the construction of Xiamen's trunk road network safety. We will strive to complete the system construction within this year and comprehensively improve the traffic safety of the main road network.
