Generation of cumulative road network service quality index for road networks in an urban area using geo-informatics approach

摘要

The transportation network in fact governs the development of any urban area through its activity clusters. The representative sample layouts have been selected and their location and other characteristics have been studied from High Resolution Satellite data. Micro level analysis was performed on these samples and number of parameters affecting road network service quality were identified and worked out. The interaction of these parameters with transportation system and their impacts on transportation system and vice versa are analyzed. Results provide an understanding on road network service quality index and the planning of the transportation network in the further developing areas and also reorganization of the activity clusters. From the present study based on selection of 8 sample layouts spread in different Land Use classes of built up areas within Nagpur Urban area, the Cumulative Road Network Service Quality Index have been proposed. These CRNSQI values are derived completely from satellite data hence presents ease of its generation and analysis. Following invention is described in detail with the help of figure 4 of sheet 3 showing cumulative weights indicating level of serviceability of roads within urban layouts within Nagpur municipal boundary.
