An attempt has been made to estimate the efficiency of road networks using three well known connectivity measures, namely Alpha (α), Beta (β) and Gamma (γ) indices, taking case studies from Indian scenario. The outcome of the study suggests that efficiency of a given road network can be approximately estimated based on the values of the three indices with a statistically acceptable level of confidence, avoiding rigorous and resource-intensive computation-works. The proposed approach finds its application in planning of new road networks, particularly where, there would be necessity for selecting an optimum solution through rapid evaluation of the efficiency of a number networks representing alternatives.
