Recently，At the road maintenance construction site of Pengwen Road, Wenjiang District, Chengdu City，Road Roller、Pavers and other large machinery and equipment roared.，The heat of the pitch rises in the night.，The workers were busy shuttling back and forth.，This is a microcosm of Chengdu Wenjiang's continuous strengthening of rural highway maintenance.，Safe travel for the masses and Vehicles“Escort”。
In recent years，Wenjiang Transportation Bureau promotes the management and maintenance of rural roads as a whole.，By accelerating big data、Deep application of information technology such as artificial intelligence in highway management and maintenance，Leading the management and maintenance of rural roads“Wisdom”New heights，The traffic conditions of rural roads have been improved in an all-round way，The more solid the traffic cornerstone of Rural Revitalization is, the more solid it is.。

The system standard enables the quality of management and maintenance to be effective.
Drive on the highway，For mass travel，The most intuitive feeling is whether the ride is comfortable.、Whether the road surface is smooth。In the eyes of highway maintainers，These intuitive feelings are quantifiable.PQI（Pavement Performance Index）Equal value。Wenjiang Transportation Bureau strictly formulates acceptance standards for road maintenance，It is required to manage and maintain the service performance of the road surface throughout the year.PQIIndex not less than 90，The excellent and medium road rate of rural roads is not less than 83%。The original management and maintenance system of rural roads has been enriched and improved.，To realize the standardization of rural road maintenance。
Formulated and issued《Measures for Assessment of Market-oriented Maintenance of Highways in Wenjiang District, Chengdu》《List of responsibilities of special personnel for key road sections》And“One way, one strategy”Documents such as the programme of work，Carry out“1+N”Highway maintenance management model，That is, 1 maintenance subject，Establish“Road chief+Sheriff”“Township road chief+Civilian police”“Village Road Chief+Auxiliary police”Management mechanism，Pass quantitative scoring assessment，Implement the responsibilities of sub-areas and sub-sections，To guide the maintenance and management of town streets。“N”A road observer，Set up a volunteer service team for Party members，Carry out special supervision in the front line of construction；Hire“Wen Xiaoai”Courier boy、Town Street Micro Grid Chief More than 20 Part-time Traffic Industry Observers，Efficient disposal of more than 600 hidden dangers of rural highway safety。
“Big data+”Promoting Intelligent Transformation of Highway Maintenance
In Wenjiang, Chengdu“Integrated platform for management and maintenance of highway bridge”Go，Real-time display of ambient temperature and humidity、Traffic load、Longitudinal displacement、Structural vibration and many other important parameters。Maintenance personnel through these data，It can realize real-time monitoring and early warning of abnormal conditions.。
“Integrated platform for management and maintenance of highway bridge”（Map provided by Wenjiang District Transportation Bureau）
“Integrated platform for management and maintenance of highway bridge”It is the big data of Wenjiang traffic.、The vivid practice of artificial intelligence and other information technologies in intelligent management and maintenance。A long time，Rural road maintenance is faced with a weak grasp of the situation.、The maintenance task is heavy、High security risks and other difficult problems，How to Transform and Upgrade the Traditional Highway Maintenance Monitoring，Only in this way can we adapt to the people's increasing demand for high-quality travel.？Traffic in Wenjiang takes advantage of the situation，Borrow“Big data+”As an important breakthrough in the transformation of rural highway maintenance wisdom.。
According to Peng Jian, the responsible person of the maintenance department.，“Integrated platform for management and maintenance of highway bridge”Platform to“Digital Highway”Construction is the goal，Based on electronic map，Professional scene preparation and construction“One bridge and one gear”“A map of the road”Electronic basic information，Use video perception、Big data analysis as a means of maintenance，By entering the bridge monitoring data、Maintenance records、Basic contents such as highway marking status，Realize the road condition、Integrated management of online monitoring of facilities and equipment，To realize the transformation of highway bridge management and maintenance from intellectualization to intelligence，The efficiency of management and maintenance has been significantly improved.。At present，The road management and maintenance platform has completed three iterative upgrades.，Integration covers the total mileage of 838 highways in the whole region.73 kilometers of road、163 highway bridges，6555 sets of well covers for ancillary facilities、4644 sets of water grates、Road traffic separation railings 31878 meters, etc.。
“Innovation+”Leading Highway Management to Improve Quality and Efficiency
Innovation，It is the first driving force for development.。Wenjiang Traffic has always paid special attention to creating a new situation of highway maintenance and management through innovation.，Increase“Four new”Technology promotion and application，Promoting Green and Low-carbon Transformation of Highway Maintenance。
In the past, highway maintenance，We often see that the damaged pavement materials are dug up and then transported away by Vehicles.，And now，At the road maintenance site，We can only see that the excavated pavement materials are crushed and processed.，And then a new modified asphalt material with better performance is added on site.，In-situ hot recycling of old road asphalt“New Technology”Renovation of old roads。In daily maintenance，In the past, we could only observe and judge road diseases with the naked eye.，Now the three-dimensional ground penetrating radar Vehicles on the road only rely on a pair of wisdom.“ Eye ”The current situation and diseases of underground roads can be accurately found.，Efficient realization of double improvement of maintenance quality and efficiency。
“We also based onGPSThe map realizes the multi-dimensional measurement and calculation of the marking.，It greatly improves the work efficiency of marking change.。Based on the maintenance data monitored and entered by the integrated platform，It can also realize the dynamic update of various maintenance information.、Intelligent query and comprehensive display，Achieve maintenance management‘At a glance’。”Peng Jian said。
It has perfect operation standards and mature management experience.，Intelligent maintenance is being applied in more and more rural road maintenance projects.。The first three quarters of 2024，Wenjiang District has always been in the forefront of Chengdu Highway Maintenance Assessment。Next step，Wenjiang District Transportation Bureau will further maintain the standard highway“Wuhua”General direction of development，Continue to deepen the construction of intelligent transportation，Focus“Sihao Rural Road”Overall goal of improving quality and efficiency of management and maintenance，Continuously improve the quality of road environment，Keep it clean、Neat、Orderly road appearance，Focus on building“Chang、Ann、Shu、Beauty”Travel environment，Improve people's sense of travel、A sense of identity。（Qi yuan）
