This idea was proposed by one of the members in Neo4j-India community. We were planning to build a travel recommender which considers the source and destination and can come up with the best transit routes, modes of transport and overnight accommodation if needed.
During a follow-up discussion, we thought of bringing OpenStreetMap for India inside a graph database like Neo4j. Neo4j provides direct OSM or Shape file import via Neo4j-spatial. We could even map further information regarding transits, hotels etc, the more information we add, the merrier it gets!
