Vehicular Ad Hoc Network (VANET) is a type of wireless network that allows communication among moving vehicles with the assistance of roadside units (RSU). Congestion in VANET refers to the situation where there are too many vehicles on certain part of a road, causing a bottleneck in the flow of traffic. This congestion can lead to delays, increased travel time, and reduced overall network performance. In addition, congestion in VANET can also lead to a higher probability of collisions and accidents, as vehicles may be unable to communicate effectively with each other or with the infrastructure. Therefore, managing congestion is a critical issue in the design and operation of VANETs to improve the Intelligent Transport Systems (ITS) in an urban area. In this paper, an adaptive traffic light signal using the assistance of roadside units is proposed. A technology has been built depends on the density of vehicles in each of segment of the roads connected to the traffic lights at the intersections. A prediction is expected to calculate the congestion on its basis and open the road automatically when congestion occurs on any direction. The results showed that the proposed model makes a stable movement of vehicles to cross the intersections in urban environments.
