Design and Implementation of Full-process Management System of Highways based on Linear Location

Abstract

Linear referencing and dynamic segmentation are becoming important means of geographical information system (GIS) development, along with the continuous development of GIS technology. They have specific applications to road maintenance, railway operation and maintenance, and pipeline and urban road management. However, traditional GIS technology only considers space and attributes; it cannot express time, which is an important dimension in the field of rural highway maintenance. To solve the data management problem in the construction-management-maintenanceoperation process of rural highways and data sharing problems among business systems of rural highways, as well as to facilitate the perfection of the full-process management system of rural highways, a full-process management basic data model of rural highways based on dynamic linear location was proposed in this study in accordance with their management characteristics, great cardinal number, extensive distribution, and relatively weak management. A fullprocess management dynamic linear referencing system for the construction, management, and maintenance of highways was established by combining the linear location technology and introducing the time dimension. Finally, a rural highway management system based on linear location was developed, and its convenience was verified by the basic data updating of rural highways in Xianyang City, China. Results show that the proposed full-process management basic data model can realize dynamic changes and trace management of the linear referencing system, while conforming to characteristic of data on rural highway management and maintenance. The built rural highway management system meets the dynamic management requirements of rural highways and can inquire the path information in a timely manner. The proposed management system can improve the accuracy and completeness of basic data by 12% and by 24%, respectively, in the process of concrete application, effectively solving the lag of basic data of rural highway.
