VANET (Vehicular Ad hoc NETwork) is emerging technology in which routing is important process from perspective of analysis and design of network applications of its kind. In this paper, existing distance vector routing protocols viz. DSDV, AODV and AOMDV are analyzed not as done earlier over grid topology, but detailed of road layout is used for analysis. As the authors know, road topologies such as Highway, Intersection and bridge are common in city or urban areas. Here, three routing protocols are run for all the road topologies to obtain more accurate evaluation. Apart from this, new routing method for opposite direction movement of vehicles is also analyzed using network simulator NS 2.34.
