The safety of vulnerable road users is one of the most important tasks a smart mobility infrastructure must accomplish. The most vulnerable users are pedestrians. A non-negligible percentage of accidents involving pedestrians occur at road junctions. To this aim, to develop a sustainable smart mobility system able to sense the presence of a pedestrian on the sidewalk, waiting to cross the road and communicate this presence to a smart traffic light, this paper investigates the suitability of a specific velocity measurement method based on raw GNSS measurements carried out with mobile devices, such as smartphones and/or tablets.

Abstract
The safety of vulnerable road users is one of the most important tasks a smart mobility infrastructure must accomplish. The most vulnerable users are pedestrians. A non-negligible percentage of accidents involving pedestrians occur at road junctions. To this aim, to develop a sustainable smart mobility system able to sense the presence of a pedestrian on the sidewalk, waiting to cross the road and communicate this presence to a smart traffic light, this paper investigates the suitability of a specific velocity measurement method based on raw GNSS measurements carried out with mobile devices, such as smartphones and/or tablets. Results have demonstrated the method's reliability, providing good and metrological comparable results when two different devices with different specifications are used.Pubblicazioni consigliate
