Abstract

This study compared older drivers' driving patterns during a naturalistic on-road driving task (i.e., eDOS driving task) with their real-world driving from the preceding four-month period. Two hundred and eight participants (Male: 68.8%; Mean age = 81.5 years, SD = 3.3 years) completed the eDOS driving task in their own vehicle which commenced from their home and followed a self-selected route. Participants' driving patterns were collected via an in-car recording devicethat was installed in their vehicle. This studyexamined the sub-trip from participants' homes to their first destination during the eDOS driving task. The median sub-trip distancewas 4.4 km (Q1 = 2.8, Q3 = 6.4). Across thefour-month period of real-world driving, participants completed a median of 151 driving trips from their home (Q1 = 103.0, Q3 = 202.7), with a median trip distance of 2.7 km (Q1 = 1.1, Q3 = 5.8). Most participants' eDOS driving task trip distance was classified as representative of their real-world driving trip distances (95.2%). By mappingGPS coordinates for driving pattern data with road types and roadways, mosteDOS driving task trips included roadways that were actively used during their real-world driving (85.0%). During the preceding four-month period of real-world driving, most participants hadvisitedthe first nominated destination during the eDOS driving taskat least once per month(77.4%).Given the increasing international interest and use of modified (local area) licences, these findingssuggest that naturalistic on-road driving tasks could be used by licensing authorities to assess potentially at-risk older drivers within their owndriving environments.
