Enhancement of Highway Asset Management Using GIS: Casy Study
摘要
Highways are a crucial infrastructure element for any city. It is important to maintain their high performance and plan the road network in a functional pattern. Spatial technologies, such as GIS, are particularly useful for integrating roadway data and enhancing their use and presentation for highway management and operation through the use of spatial relationships and maps. This paper presents a GIS-based system that serves as a platform for all aspects of the pavement management system (PMS) process. The resulting map system significantly enhances the maintenance process. The use of GIS technology is the most logical way to relate the diverse, yet relevant, data. This paper examines the condition of road sections in a selected area of Al-Muthanna governorate. The sections have varying condition states due to factors such as weathering, insufficient drainage, ageing, traffic load, and lack of routine maintenance. The overall condition index (OCI) is used to assess the state of each section on a scale of 1 to 10, with most sections falling below 5. The paper presents two strategies for maintaining and inspecting the network that highway agencies and road engineers could adopt to save money and extend pavement life in a functional manner. Also, providing strategies of maintenance for each section with the help of ArcGIS software, encourages those skilled with road maintenance to establish priorities and adding updates into the map. Additionally, the study highlights the importance of recording all road information, including construction details, distress type and severity, and maintenance and rehabilitation processes, to inform future actions.
