A study of users’ acceptance and satisfaction of emergency call service

International audienceIn recent years, there has been rapid and significant development of road transport technologies in order toreduce the number of killed and injured people on roads. These include safety technologies, emergency callsystems (eCall), and advanced traveler information systems. The eCall system is an automatic in-vehicleemergency call service, which is mainly used for notifying emergency services about dangerous road situationsand their exact location. In this paper, an eCall platform prototype is developed to allow quick andefficient rescue of injured people in dangerous road situations. The eCall function is developed and installedin nomadic devices (e.g., smartphones and tablets). Large-scale field operational tests were conducted in realsettings to assess the impacts of the eCall function provided by in-vehicle nomadic devices. More precisely,experiments were conducted by more than 250 participants with different sociodemographic profiles in orderto study the users’ acceptance of the use of the developed eCall function for large-scale usage. The collecteddata are analyzed, and results are reported. Performed experiments showed the usefulness,acceptance, and satisfactory performance of the eCall service
