  As vehicle population has been increasing on a daily basis, this leads
towards increased number of accidents. To overcome this issue, Vehicular Ad Hoc
Network (VANET) has come up with lot of novel ideas such as vehicular
communication, navigation and traffic controlling. In this study, the main
focus is on congestion control at the intersections which result from unclear
ahead. For this purpose, a city lane and intersection model has been proposed
to manage vehicle mobility. It shows the actual vehicle to vehicle and vehicle
to traffic infrastructure communication. The experiment was conducted using
Network Simulator 2 (NS 2). The implementation required modelling the road side
unit, traffic control unit, and on-board unit along the roadside. In the
simulation, including traffic volume, the distance between two signals,
end-to-end delay, packet delivery ratio, throughput and packet lost were taken
into consideration. These parameters ensure efficient communication between the
traffic signals. This results in improved congestion control and road safety,
since the vehicles will be signalled not to enter the junction box and
information about other vehicles.
