Trams are effective alternatives to private car as means of travel in Moroccan towns and cities, and on this basis they are being promoted by the government. However, issues relating to their impact on road safety are one of the main societal concerns today. Indeed, trams share the same road network with all road users. Ensuring that the network works efficiently for all modes and users – cyclists and pedestrians as well as car drivers – presents a significant, but essential, challenge for those who plan, design and fund the transport system. In the light of this, many research studies have shown that poor road design may enhance the driver's tendency to error and misjudgement and lead to unwanted situations (accident, pre–accident, congestion, etc.).
Moving the focus of research away from the driver in isolation and focusing more on the interaction of the drivers and the changing environment, through which they move in time and space, can be regarded as hard core among road safety problems to investigate. This supposes assessing human abilities and limitations and ensuring that the resulting systems that involve human interaction are designed to be consistent with these human limitations and will be a full proof system.
The general aim of this article is to further knowledge about the influence of tramway and the surrounding environment on car's driver behaviour. Understanding these influences, involves conducting a systematic review of the cognitive tasks related to driving and identifying the hazards that can arise at each task, and what factors can make these more or less likely to arise, considering the environmental design and behavioural factors. To achieve that, the Hazop approach is conducted for this study. Concerning data collection, our methodology includes site visits to record user behaviour and questionnaires to determine the opinion, concerns and knowledge of car drivers in interaction with the tram environment.
