Vehicular Ad-hoc Network (VANET) is very useful to use in now a day. Communication is based on the Vehicle to the Vehicle and Vehicle to the roadside unit. VANET provides the wide range of applications in the areas of safety, data transfer, entertainment and data transfer optimization. One of the keysuses of VANET is vehicle traffic optimization. The traffic flow is calculated in this paper. In order to calculate the traffic between two points, roadside unit which are regarded as static node are placed at each point. The main challenge of VANET routing is to route the packets from correct node to correct destination. VANET is also capable to cope with various difficulties arises during transmission of data due to frequent topology changes, disconnections and rapid speed of vehicles etc. In this paper AODV protocol is used to run nodes in the network. AODV must keep the roads to targets that are not in active contacts and enables packets to quickly get routes for new destinations. Various matrices like throughput, delay and packet delivery ratio are calculated using NS2 simulation. This paper represents 100 running nodes using AODV protocol.
