Backup Warning Signals: Driver Perception and Response

摘要

This report describes the findings of three experiments that concern driver toacoustic signals that might be used for backup warning devices. Intelligent warning devices are under development that will use vehicle-based sensors to warn backing drivers of the presence of objects behind the vehicle. The research described here is part of a larger project concerned with the human factors of these warning devices. Specifically, the questions of interest center around what warning information to provide, when to present it, and how to display it. Based on previous work (Lerner, Kotwal, Lyons, and Gardner-Bonneau, 1996; Huey, Harpster, and Lerner, 1996), this research focuses on acoustic signals, with the objective of contributing to the development of a set of recommendations for the human factors aspects of backup warning systems.
