Study On The Highway Pavement Management System

With the rapid development of highway construction in our country, how to acquire automatically the highway information, to achieve effective maintenance of the highway is the research focus of the highway pavement management system. Papers from the highway pavement management system, this paper mainly studied:highway pavement management system management system, the framework of highway pavement data needed and their acquisition methods, as well as highway pavement data analysis method.In highway pavement management System framework of the study, drawing on foreign and our country in the past research pavement management System, implementation experience, combined with the latest development of science and technology achievements with the actual situation of the highway maintenance management at present in our country, realize the network based on GIS (Geographic Information System) highway pavement management System frameworkData needed for pavement management system and its acquisition method research, the required data is roughly divided into:basic data, traffic data, traffic data types. Through the analysis of existing data collection methods, and combining the actual situation, highway data acquisition is realized.In the study of highway pavement evaluation and maintenance, the dynamic based on multi-granularity traffic data analysis. The method for dynamic traffic demand and road network traffic congestion status analysis, studied the trajectory, traffic flow, road congestion status data such as similarity of space and time and space correlation and time correlation measure; On this basis, through clustering, prediction, association rule mining, anomaly detection and other operations, for highway maintenance and management.
