Road network, structure, evaluation, population density, modeling, GISAbstract
Infrastructure like roads has a major role in the development of any urban form. Efficient road network structure is necessary for a sustainable transportation system. The present study attempts to examine the performance of existing city-level road network structure using Geographical Information Systems (GIS). The criteria for evaluating the effectiveness of the road network structure considered in the study are connectivity, accessibility, spatial pattern and development. The study focuses on proposing a “Road Network Structural Performance Index” (RNSPI) which indicates the efficiency of the road network structure at different locations in the city. The study also attempts to establish a relationship between urban road network structural evaluation criteria and human settlements. The results of the study indicated that the locations with deficient road network have to be looked up for network enhancement by planning professionals in order to optimize the road network in the city. The positive correlation between population density (PD) and RNSPI also seems to be an interesting outcome of the study. Emerging technology namely Arc GIS software has been used for location finding, buffer analysis, feature extraction and data representation. Implementation of GIS in road network structural evaluation made the analysis more feasible and accurate.
