Connectivity in vehicular ad hoc networks (VANETs) exhibits stronger challenges than that in other general ad hoc networks. In this paper inter vehicular connectivity is analyzed among different length of vehicles that are running along the city roads. Considering the traffic signals, connectivity among the vehicles waiting at different intersections is analyzed taking the safe distance into account. Besides, car following model is used to formulate the connectivity among vehicles with different speed on a multi lane road with several intersections. Simulation results show that performance in terms of packet forwarding is very good for the vehicles with least speed. Duration of connectivity among vehicles at any intersection is reduced for the vehicles with higher speed.
