Abstract: This paper is aimed at providing an overview of the evaluation process of an Advanced Driver Assistance System focused on the Safe speed and Safe distance concept (named SASPENCE) developed within the framework of the Integrated Project PReVENT (Preventive and Active Safety Applications). The SASPENCE system was designed and developed in order to be used as a driving support in keeping safe speeds and safe distances in the longitudinal behaviour. Its final evaluation was carried out in two European countries, namely Spain and Italy, through the execution of field tests in real driving conditions with the participation of a total group of forty subjects (twenty per site). This research shows the results obtained from the Spanish field trials performed with the SASPENCE prototype vehicle. During these experiments, objective variables, video recordings, different questionnaires and the ‘Wiener Fahrprobe’ in-car observation technique were used. The results showed a potential safety improvement of this kind of support system and users’  perception of the SASPENCE system was found positive. Nevertheless, some improvements were identified for future iterations of the system development in order to optimise its benefits and increase users’ acceptance.
