Abstract
The expressway is necessary for the development of the modern transportation industry, and the level of expressway construction reflects the overall grade of national or regional economic development. In order to process the expressway road property data information, based on the current mainstream Windows operating system, this study utilizes Geographic Information System (GIS) development technology, road video processing technology, and spatial data mining method to design and develop an expressway video and road infostructure GIS data production system. The system designs a multi-layer distributed application model in accordance with the ideas and methods of GIS engineering and the characteristics of road production data. In addition, according to the characteristics and specification requirements of basic geographic data, the road production database of spatial data and attribute data integrated storage is constructed by combining database and spatial data engine. Through the development of the GIS data production system for expressway video and road infostructure, various functions such as generation of road property data, dynamic management of road infostructure, and visualization of spatial information have been realized. The system focuses on improving the production efficiency and automation level of expressway production data and meets the construction requirements for modernization, informatization, and intelligence of expressways.
Highlights
This study addresses the requirements of information processing of road property data; gives full play to the spatial data organization capability, spatial information calculation capability, and geographic knowledge service capability of Geographic Information System (GIS) [5]; and establishes a set of intelligent, efficient, and scientific expressway data production system, so as to improve the work efficiency, work quality and automation level of operators and help managers make informative and scientific decision-making [6]
The system aims to establish an expressway data production platform to realize such functions as road property data classification, video configuration management, video track fusion, video fusion cutting, and video problem checking and repair, so as to help field staff handle on-site data collection in a highly efficient and automatic manner. The architecture of this GIS data production system for expressway video and road infostructure is shown in Figure 1, which can be mainly divided into four layers, i.e., infrastructure layer, data service layer, software service layer, and user layer
The spatial database is the core of the GIS data production system for expressway video and road infostructure
Summary
With the continuous acceleration of China’s expressway construction process, expressway road property data demonstrate more massive and complex characteristics [1]. The requirements of modernization, informatization, and intelligent management of expressways have promoted the development of new expressway data production systems [3]. This study addresses the requirements of information processing of road property data; gives full play to the spatial data organization capability, spatial information calculation capability, and geographic knowledge service capability of GIS [5]; and establishes a set of intelligent, efficient, and scientific expressway data production system, so as to improve the work efficiency, work quality and automation level of operators and help managers make informative and scientific decision-making [6].
