Evaluation of an Assistance System for Elderly Drivers When Approaching Stop Intersections

Abstract

The study focused driver assistance systems on stop intersections since the typical accident involving an elderly driver occurs at a stop intersection. The three-step assistance system, giving ’advisory’, ’warning’information and brake intervention, was evaluated in the JARI proving ground. The elderly participants were surveyed on their usual driving by a driving recorder before the experiment. The results showed that the deceleration timing became earlier and approaching speed to the stop intersections became slower when the assistance system was applied to the elderly drivers who didn't stop in the above-mentioned survey. The subjective rating also indicated higher acceptance of the system.
