AI patrols roads 45 times faster! Big data lights up the smart "lighthouse" of Guizhou highways

"It takes 15 seconds per square meter to manually inspect cracks, potholes and other road defects on highways. Using AI technology only takes 0.3 seconds, and the efficiency is increased by more than 45 times." On May 27, a conference was held in Guiyang At the "Deep Integration of Digital Economy and Real Economy" forum, Zhang Yin, vice chairman and general manager of Guizhou Expressway Group Co., Ltd., shared typical cases of digital intelligence on Guizhou expressways.

By the end of 2022, Guizhou’s expressway mileage will reach 8,331 kilometers, with 28,200 bridges and 2,535 tunnels.

"The 'high-speed plain' has been built, but we Guizhou traffic people have 'growing pains'." Zhang Yin said, faced with mountainous highways with high altitude, changeable climate, high bridge-tunnel ratio, many bends, How to carry out real-time monitoring, early warning and dispatching on roads with characteristics such as long downhill slopes? Disease care and rescue? How to release real-time road information to drivers and passengers?

Zhang Yin believes that intelligent maintenance of highways is an important application scenario of artificial intelligence and big data models.

Relying on the AI ​​inspection system equipped with high-precision cameras and radar devices, it can accurately identify most road defects such as cracks, potholes, ruts, etc., and perform timely repairs through the system dispatching orders, achieving "detect disease-dispatch" The closed-loop management of "single maintenance-inspection results" enables early detection and early treatment of minor diseases. Because of the precise identification ability of artificial intelligence, even in the minor repair stage of potholes and diseases of 0.01 square meters on the road, it can be effectively controlled, thereby extending the period of major and medium repairs.

Emergency dispatch is also one of the application scenarios of artificial intelligence on highways. In 2021, Guizhou Expressway Group launched and ran the "Dispatch Cloud" system, establishing an all-road network, all-weather, all-element road network perception system to allow timely detection of incidents, unified dispatching and command, timely rescue arrival, and accident arrival and handling The time was shortened by 3 minutes and 7 minutes respectively.

Through data aggregation, AI monitoring and other technologies, Guizhou Expressway Group has also achieved flattened and unified online management and dispatching of 119 pairs of service areas. By monitoring traffic flow, vehicle ownership, vehicle models and more than 3,000 sales Comprehensive analysis of product data can provide real-time understanding of the operating status of the service area under its jurisdiction, and optimize resource allocation accordingly to achieve a personalized operation strategy of "one area, one configuration", which not only reduces investment costs, but also provides the public with more accurate information. , more adapted services.

Zhang Yin said that realizing enterprise digitalization is not something that can be achieved overnight. It needs to turn digital transformation from experiment to practice from many aspects such as service model, internal management, digital technology application, talent training, etc., and continue to move towards true "automation" Moving forward in the direction of ", intelligence, and intelligence". She likens these practices to lights lit on a lighthouse and believes that only when more and more lighthouses are lit can the light of value in the digital future shine brighter. ”
