In this paper, we initiate a framework to address the capacity scaling trends in vehicular ad hoc networks (VANET)s with arbitrary topologies. Towards this end we utilize the conventional definition of transport capacity in which destination nodes are chosen at random by the source nodes. Also, to get more VANET-specific, we set up a new variation of transport capacity in which the destination nodes are again chosen at random, but this time are within a distance d of the source node which is called the distance-limited capacity. Emergency and accident avoidance scenarios are just, some of the direct applications of distance-limited capacity. Moving on further, we study the effect of infrastructure node deployment in the capacity analysis of VANETs. Wepsilave initiated this trend with our focus on the distance-limited capacity of a single road VANET. Using analytical expressions we show that exploiting any number of infrastructure nodes beyond a certain amount, enhances the achievable capacity.
