HUMAN FACTORS DESIGN OF COLLISION WARNING SYSTEMS

Delco Electronics has been involved in the development and production of several collision warning systems in the last several years. The successful implementation of collision warning systems depends heavily on effective human factors design to accomplish two paramount goals. These are: 1) the system must alert the driver quickly, but not startle him while it is orienting the driver's attention toward the location of the hazard; and 2) while the system must identify every potential collision, it must not produce alarms that the driver considers "false alarms," such as potential collision situation that the driver is aware of but does not need assistance in identifying. Designing a system that never produces false alarms is an impossibility, however, Delco Electronics has adapted a methodology to determine the bounds on collision warning distances, which should minimize the false alarm rate. A series of road tests utilizing human subjects were conducted to carefully measure when, how quickly, and how severely drivers chose to brake when they approached stationary and moving vehicles. In addition, potential collision events were categorized by two criteria, events requiring driver's immediate attention and events requiring the driver to take immediate action. This partitioning was used to configure warnings that elicited appropriate driver actions while minimizing annoyance from false alarms. Cautionary warnings were implemented using audio, visual, and proprioceptive modes. These warning interfaces were designed using data from rapid prototyping tests and human factors guidelines and have been successfully integrated into two FOREWARN collision warning vehicles. This paper concludes with discussion of need to establish international standards for collision warning system interfaces.
