Cyclists (and pedestrians) are the most vulnerable road users since cyclist-vehicle collisions often result in severe injuries and have high fatality rates with respect to other types of collisions. In particular, intersections are one of the most critical areas in a road network given the high number of conflicts and accidents occurring at these locations. Existing data collection… Read More
