In urban traffic, roundabouts have been considered as an alternative traffic facility that can improve safety and operational efficiency, compared to un-signalized intersection. But in Morocco where roundabouts are relatively new, the concept is not rooted in the road culture of drivers. Moroccan drivers are used to the traffic lights telling them what to do. Roundabouts involve drivers using their own judgments at an intersection, so roundabouts negotiation can be confusing for drivers who are not familiar with their use. This fact has guided our research in this area to an approach that takes into account the Moroccan road context and human factors in this context. This article presents a detailed analysis of driving task to determine key functions performed by drivers as they approach and navigate through roundabouts. Our analysis aims to understand the mechanism of driving performance in roundabout’s environments, to predict how drivers might respond , to identify roundabout elements that play a role in incorrect roundabout negotiation and therefore to suggest measures for improving
drivers’ abilities to properly negotiate roundabouts.
