ASSESSMENT OF ROAD CONNECTIVITY USING GIS: A CASE STUDY OF HAILAKANDI DISTRICT
(National Institute of Technology, Silchar, 2026) Chauhan, Rohit
In most districts in India, the existing road network is unable to meet the increasing travel demand. Effective utilisation is required due to the transportation system's high development costs, and this can only be achieved with proper connectivity. In this study, an attempt was made to analyse and evaluate the road network structure of Hailakandi District in terms of its connectivity and coverage. The District was analysed three times, considering different types of analytical units, i.e., District, Blocks and Grids of 10 sq. Km, and a comparison was made among the results obtained using different analytical units. This comparison highlighted errors that occurred when using a smaller area size as analytical units in connectivity analysis. Hence, this research suggested that the analytical area should be kept as large as operationally feasible. Also, this research sought to improve the existing methodology for connectivity analysis by introducing a new index, the c-index that accounts for the effect of road category. Based on the findings, a set of recommendations was also proposed.
