Topological Indices and Connectivity Indices of Delhi Metro Rail Corporation

New Delhi is the capital of India and a highly dense area in India. Many people travel from their homes to their corresponding offices, colleges, and factories. A well-connected public transport network is required for this purpose. The well-connected metro rail network is significant for economic growth and public transport. From time to time, expand this network for future traffic load. In this paper, we calculate several topological and connectivity indices, graph energy for the DMRC (Delhi Metro Rail Corporation) phase I and phase II, to understand how these quantities can improve the DMRC network and find a connection between them, if any.
