Effects of Different Vehicle Deceleration for Pedestrian Crossing Decisions

Abstract

As a vehicle becomes fully automated, a vehicle without a driver is expected to operate on public roads. Therefore, the communication between a pedestrian and a driver may be lost, and a pedestrian feels less safe. To improve the sense of safety, we propose a method of providing information step by step based on distance. This paper explains a method to communicate the vehicle’s intention to give way through deceleration control during the approach phase. We investigate the effect of the proposed method on pedestrian crossing decisions. The experiment using a VR simulator shows subjects feel that they can cross a road by the proposed method by comparing with a constant deceleration control.
