A New Activity Estimation Method of Pedestrians with Coordination between Intersections in P-VCASS

In this study, we focus on Pedestrian-Vehicular Collision Avoidance Support System (P-VCASS). P-VCASS is a system to support collision avoidance between vehicles and pedestrians. P-VCASS grasps the relative locations of vehicles and pedestrians by exchanging the GPS information with each other. P-VCASS warns drivers if it estimates the possibility of their collisions. The former P-VCASS is intended for adult pedestrians who are sensible to dangerous actions. In this paper, we propose a new activity estimation method of pupil/infant pedestrians who are not sensible to dangerous actions with coordination between intersections in P-VCASS. This method has two advantages. First, it is able to prevent the jumping out accidents of the pedestrians. Second, it is able to apply to the complex intersections by sharing a traffic situation between intersections. We show the validity of the proposed method by experiments using a vehicle which carries an in-vehicle apparatus in a intersection with roadway and sidewalk. As a results, we found that the recognition of a vehicle driver is possible before pedestrian jumps out to roadway in a complex intersections.
