The structural performance of any transport network may be mainly evaluated using connectivity, accessibility, hierarchy and morphology. The evaluation of accessibility is one of the most important aspect in defining the performance of a road network structure. The present study is concerned with proposing a methodology for the city—level opportunity (or) urban services and distance based accessibility evaluation. The various opportunities (or) urban services like schools, colleges, ATM’s, banks, hospitals, police stations, petrol bunks, bus stops, parks and theatres up to a specified distance of 0–5 km radius were considered for the analysis. The weights were assigned to different opportunities and were analyzed using Weighted Scoring Model. The Mean Weighted Accessibility Index has been determined for each location to identify the level of accessibility in a particular location. The study attempts to define the level of road network accessibility at different locations in the study area. In the later stage, this study tried to establish the relationship between the number of opportunities and trip attraction rates and the results were discussed. The present work was also intended to prove the efficiency of Geographical Information Systems in opportunity based accessibility assessment.
