Extensibility of vehicle-to-roadside system to vehicle-to-pedestrian system using RFIDs

In the former papers^[1][2], we presented research information on a ldquoVehicle-to-roadside system using RFIDs for detecting road shouldersrdquo. As a result, we found that RFIDs can be used for road-shoulder avoidance systems. This paper argues about the extensibility for pedestrian avoidance systems. The basic concept is the consideration of the relative velocity between a vehicle and a pedestrian. Three models for a pedestrian´s movement are shown and examined in this paper. After taking some characteristic issues into consideration, the results are such that the model that needs the least amount of calculation should be implemented into the system. Even though it may causes some unnecessary avoidance, the ldquoSimplest modelrdquo should be implemented in this case.
