EVALUATION MODELS IN ROAD SAFETY: A SYSTEMIC ROADMAP

The evaluation of road safety actions' effectiveness is one of the main activities carried out in road safety research. Safety actions refer to safety measures such as regulations or technology-based safety system. Each safety action follows a detailed set of functional specifications according to specific goals. Evaluation refers to the process of assessing the designed safety action against these specifications and these goals in a context. We address evaluation activity for the decision, optimization or design processes. To support these objectives, we use the ability of the evaluation activity to create new knowledge. However, we have the habit to deal this activity through existing indicators that are not enough reconsidering or/and that their design process is not enough formalized. This paper deals with the construction of a theoretical framework to be used as a guide for the evaluation process in terms of building of new evaluation models for specific stakeholders and viewpoints based on the expertise of evaluators, on the documentation of previous evaluations and on a theoretical model.
