An approach for automatic updating of GIS road segments for a pavement management system (PMS)

The GIS-T (Geographic Information System for Transportation) dynamic segmentation (DS) technique can be effectively employed by pavement management systems (PMS) to provide more detailed information on road conditions by using the segments. In most cases, segments present attributes that change frequently either spatially or non-spatially. In order to ensure correct and successful decision-making processes in transportation-related activities, regular updates and revision of segmented data are essential. Manual updating of the segmented data is a complex and time-consuming process. Thus, it is highly beneficial to provide an easy and efficient way to update segments. This paper presents a rule-based method for automatic updating of road segments using the DS technique. The proposed approach was implemented for the Road Maintenance and Transportation Organisation (RMTO) of Iran on road network data of Tehran city. The experimental results indicate many useful aspects of this approach that made it efficient. These include a remarkable decrease of time, cost, occurrence of human-type errors, and complexity involved in update operations.
