Application of smart traffic safety scene
①All-weather driving safety guarantee: fog area driving guidance, ice and snow road warning, and road weather monitoring
②Improvement of traffic safety facilities in all road conditions: ultra-visual distance dangerous road condition warning, enhancement of traffic safety facilities for “four dangerous” sections (dangerous sections, geological disaster sections, water damage prone sections, and ice-prone and snowy sections)
③All-round traffic incident monitoring: road incident monitoring and warning, slope flying rock monitoring and warning, construction area monitoring and warning
④All-digital traffic safety facility operation and maintenance: traffic safety facilities asset management, traffic safety facilities repair and maintenance
Classic scenes
Road meteorological monitoring
The road meteorological monitoring system uses pulse radar (a micro power consumption radar) for detection with a distance of 0~7m. It is powered by solar energy other than external power supply, with adjustable launch angle, better material judgment skills, and abilities for water-content monitoring, liquid level measurement, water icing status monitoring, etc. It can provide microclimate meteorological data of road sections, including atmospheric temperature, humidity, visibility, road surface temperature, road surface humidity, road surface water accumulation or icing, particulate matter concentration, etc.
Ultra-visual distance dangerous road condition warning
1.After receiving the opposite signal, the word "passing" is displayed and voice prompts are sent at the same time.
2.The relay will enhance transmission when the bend is too large and the visual distance is not smooth.
3.When the radar detects the car coming in front, it will automatically send a signal to the opposite road pile.
Asset management of traffic safety facilities
Smart project cases of Songyan highway
Songyan highway, a “smart highway”, is located in Yanqing of Beijing 2022 Olympic Winter Games. It is the only local road entering and leaving Yanqing except Beijing-Chongli Expressway, and plays an important role in serving and ensuring the Olympic Winter Games.
The “smart highway”- Songyan highway was constructed by UNISITS Technology Co., Ltd. The phase I project began in June 2020 and was completed in October 2020, with traffic effect reported by media and unanimous praise from highway operators and all sectors of society.
