Paper Title
Impact of Congestion on Tourism

Abstract
Road traffic attracts the attention of the public. It is a complex phenomenon, on the one hand, because of the large number of actors participating in it and, on the other hand, because of the character of the network where it takes place. The most striking phenomenon in road traffic is the congestion that feeds many user discussions, which is less and less accepted by them. In fact, no current city has a traffic program. The problem is entirely new, it was unpredictable fifty years ago. We are beset by the automatic triggering of the consequences. We were interested in the theoretical study of traffic jam to understand the why of how and understand the different models of traffic. Macroscopic models that describe traffic at a high level as the flow of a fluid without distinguishing its components. The traffic is represented in a global way by using characteristics like throughput, speed and density: Totally Asymmetric Exclusion Model (TASEP) which is considered as an archetype of transport models as well as the Nagel-Schreckenberg model. (Nasch) which is a simple model of cellular automata for road traffic that can reproduce traffic jams. The latter shows how these can be considered as an emergent or collective phenomenon due to interactions between vehicles on the road. Transportation is always an integral part and a key element of the tourist experience since tourists expect safe, reliable and efficient transportation. Traffic jams are a major problem for tourists who have little time for activities in the city they visit. Keywords - Road Traffic – Congestion – Cellular automata
