National And Provincial Trunk Highway Information System Function Requirements And Research On Decision Support Method

With the adjustment of the national highway network,the mileage of major national highways and provincial highways across the country has increased significantly,which has brought huge challenges and pressures to the daily maintenance and management tasks of highway maintenance management agencies.The rise of the "Internet +" integration model and the development of advanced technologies such as artificial intelligence have brought new opportunities for the integrated development of transportation.Under the traditional maintenance concept of "reconstruction and light maintenance" and an unsound and unscientific maintenance decision-making system,road maintenance management decisions are still mainly based on empirical decisions,and cannot meet the needs of social development for fast,efficient and high-quality road maintenance services And requirements.This article first elaborates the research background and research significance of the subject,summarizes the status quo of various researches related to this subject at home and abroad,and pave the way for the rest of the article;and then the related concepts of this article and the current status and existing road maintenance management Preliminary analysis of the problem is carried out,the common road diseases and their causes are discussed,and the influence of road diseases on the normal operation of traffic is discussed.Secondly,in combination with the relevant requirements of transportation work,a method for constructing national and provincial trunk highway information system functional requirements is proposed,and a highway maintenance decision support analysis method is studied.Specifically,it includes the following two aspects: 1)the use of the fuzzy comprehensive evaluation method is used to establish a highway performance evaluation model,and the selection and quantification methods of evaluation indicators are studied;According to the model,the preventive maintenance time of highway major and medium repairs is predicted.Finally,based on the actual work of maintenance and management in Banan District,a national and provincial trunk highway information system in Banan District was constructed;according to the fuzzy comprehensive evaluation model,the effect of road maintenance and management in Banan District was evaluated and analyzed;the neural network model established The preventive maintenance time for major and medium repairs in Banan District has been verified.In the end,it is concluded that the construction of the Banan District National and Provincial Arterial Highway Maintenance Information System can meet the needs of regional road maintenance and management,and the constructed data model can solve practical work problems.
