Recently, Gaode map released the digital management and maintenance system of road traffic facilities. It is reported that the system digitizes all elements of road network facilities based on high-precision maps, supports the digitization and intellectualization of daily inspection and maintenance management through AI intelligent terminal, integrates intelligent management and maintenance platform, helps road management units realize active management and maintenance and intelligent decision-making, and helps road traffic management and maintenance mode upgrade from responsive to active < p > according to Gaode map, through the early implementation pilot in Guangxi, Yunnan, Zhejiang and other provinces, the digital management and maintenance system of road traffic facilities helps the owner improve the management efficiency of traffic facilities by 90%; The patrol inspection quality of the maintenance company was improved by 60% and the workload was reduced by 80% < p > by the end of 2020, the total mileage of national roads has reached 5.198 million kilometers, and the urban roads have exceeded 450000 kilometers. Among them, the expressway ranks first in the world with a traffic mileage of 161000 kilometers. Millions of kilometers of roads are equipped with a large number of signs, markings, guardrails, electromechanical and other transportation facilities. These facilities are closely related to traffic safety and driving order < p > Dr. Jiang Ming, a researcher of Gaode intelligent transportation, said that the standardization of road traffic facilities and the timeliness and effectiveness of daily inspection are important guarantees for road safety and related to the vital interests of travelers and managers. In the past decade, with the rapid development of China's road network, a large number of traffic facilities are "less accounts, difficult to evaluate and difficult to maintain accurately", which not only has safety risks, but also implies management responsibility risks < p > according to relevant research results, the development of road traffic facility management and maintenance will go through three stages: static management and maintenance, responsive management and maintenance to active management and maintenance. Active management is the fundamental way to solve the above pain points. Through the research and development of digital management and maintenance system of road traffic facilities, Gaode helps the development of road traffic management and maintenance technology to "initiative". There are three core technologies in the system. First, aiming at the pain points of current chimney management, build a high-precision map chassis with all elements digitization to provide support for digital and collaborative management; Secondly, aiming at the pain points of heavy labor load, difficult evidence collection and high risk of manual inspection, AI inspection terminal is developed to assist manual active detection and quantitative positioning of diseases, so as to provide means for intelligent inspection; Third, build an intelligent management and maintenance platform to help road management units realize active management and maintenance and intelligent decision-making < p > to realize the digitization of road traffic infrastructure, the key is to have a high-precision map that can be used and affordable by traffic management institutions. According to the practice of road traffic management, Gaode has added more than 300 traffic facility element models on the basis of traditional high-precision maps. Form an "asset map". Relying on AI technology, the production cost of high-precision map is reduced. Relying on high-precision maps, integrating static and dynamic data to realize "one map of dynamic and static data of road traffic" < p > in terms of road patrol inspection, Gaode road traffic facilities digital management and maintenance system relies on AI terminal to establish a new mode of integrated patrol and maintenance, and assist manual personnel to improve the quality of patrol inspection < p > during patrol inspection, AI patrol inspection terminal can automatically find road diseases (covering the damage of pavement and traffic safety facilities), locate them on the corresponding lane of the electronic map, and update them monthly to help relevant management units master the road disease information in time < p > < p > integrating the above core competencies, on the basis of managing the facilities well, integrating Gaode traffic big data, industry norms and evaluation algorithms, the intelligent decision module in Gaode road traffic facilities digital management and maintenance system can help road management units actively find potential safety hazards and diseases, study and judge early warning problems, and form a systematic optimal scheme, Support active management and intelligent decision-making < p > for example, high-risk driving behavior is the key cause of traffic accidents. By exploring the causes of traffic accidents and setting up traffic facilities scientifically, the risk of traffic accidents can be reduced without rain. According to the big data of Gaode transportation, behind every serious accident causing death on the expressway, there are more than 17 potential minor accidents and 3000 bad driving behaviors of three emergencies (sudden braking, sharp turning and sharp acceleration) per month. Based on Gaode traffic big data, the digital management and maintenance system of road traffic facilities can screen the causes of traffic accident prone sections, high-risk driving behavior prone sections and speed mutation prone sections, and help the road management to refine and improve relevant facilities
