Safe-D: Safety through Disruption

Examining Senior Drivers’ Adaptation to Mixed-Level Automated Vehicles: A Naturalistic Approach – Phase II Analysis of the Naturalistic Driving Data


Abstract

This study is envisioned as a follow-on to a recently-completed 2017 Safe-D project (Phase I). The first phase was focused on how driving exposure to automated vehicle technologies (AVT) can change how seniors, a particularly vulnerable and growing segment of our population, use and accept AVT over time. A variety of self-reported subjective data were analyzed to investigate participants’ attitudes towards AVT. Analyses revealed that seniors’ attitudes towards AVTs correlated positively with driving exposure. In addition, traditional naturalistic driving study (NDS) data were also recorded during the Phase I data collection, encompassing multi-channel video, GPS, lane tracking, and acceleration. The goal of the Phase II follow-on proposed herein is to analyze these already-collected NDS data to evaluate the safety and mobility benefits of AVT for senior drivers. Behavioral and performance comparisons will be made with that of seniors driving non-AVT vehicles, younger drivers driving the same AVT-equipped vehicles, and with trends in the subjective data collected during Phase I. It is expected that the integrated results of Phase I and II together will provide stakeholders (e.g., OEMs, governmental regulation agencies, and safety advocacy groups) with the evidence needed to document and enhance the safety and mobility benefits associated with use of AVT by seniors. Additionally, it will also produce information which can help with their adoption and acceptance of these technologies. Regardless of the inherent safety-enhancing promise AVT holds, any technology which is neither accepted nor voluntarily used will fail to truly move the needle on public safety.
