Spatial Pavement Information System for Transportation Networks Based on Distress Features in Nagpur City Using RS and GIS

Preservation, maintenance and rehabilitation of pavements need continuous information through monitoring for their assessment. The deterioration rate of the pavement surfaces in developing countries like India is more due to a sudden rise in the automation industry which was not thought of during the planning stage of the road network. Increase in motorized vehicles has led to early failure of the roads which need to be properly maintained by carrying out the maintenance work to have a longer service life. Pavement Information System (PIS) is a valuable tool for evaluating the rapid deterioration of roads. PIS stores and compiles a large amount of data that are frequently collected on a timely basis. The new era of the pavement information system is utilizing the Remote Sensing and Geographical Information System. The present study analyzes the major pavements in Nagpur city. For these selected roads, the different types of distress conditions on the roads were collected and were represented on the high-resolution satellite map. From these data sets, a Spatial Pavement Information System (SPIS) was developed for Nagpur road network using ArcGIS software. The management system involved the development of distress indices which were calculated based on the frequency and types of distress. The different pavements were then prioritized based on distress indices for maintenance scheduling. This research paper provides a spatial method which helps prioritize pavements for maintenance and rehabilitation to improve Level of Service of the road.
