Ningxia builds a three-dimensional inspection network of "human patrol + technical patrol" to build a strong winter road safety defense line

China News Service, Yinchuan, November 9 (Reporter Yang Di) The reporter learned from the Ningxia Transportation Department on the 9th that Ningxia's highway management and maintenance units have established a "human patrol + technical patrol" three-dimensional inspection network to build a strong winter road safety defense line.

Affected by the El Niño phenomenon, the uncertainty of atmospheric circulation in winter has increased, and the risks of extreme emergencies such as short-term heavy snowfall, freezing rain, and local icing and fog have increased significantly. Ningxia's highway maintenance is facing severe challenges.

To this end, Ningxia insists on technological empowerment and builds a dense inspection network. At present, Ningxia Communications Construction Investment Group has deployed more than 20 drone airports and 1 vertical fixed-wing drone along the highway, with an inspection mileage of 702 kilometers. The drone is connected to the self-developed road-air integrated low-altitude operation service platform and supports functions such as one-click take-off and landing, automatic return to home, and aerial shouting. The video recognition algorithm can automatically identify traffic accidents, foreign objects on the road, illegal parking in emergency lanes, road congestion and other events, and automatically generate work orders directly to the disposal unit, linking from "seeing" to "disposal".

At the same time, Ningxia highway maintenance units and meteorological departments have customized grid-based weather warning products to monitor snowfall intensity, road surface temperature in real time, and short-term forecasts. Highway video surveillance has been deployed in pairs every 2 kilometers. Manual inspections, video surveillance, drone inspections and other means have been comprehensively used to increase the frequency of road inspections before, during and after snow, so as to achieve early detection and early disposal of dangerous situations.
