“… 17 This is of importance for road safety policy makers and licensing authorities who mainly rely on visual acuity for assessing fitness to drive, despite the significance of contrast sensitivity being highlighted in a large body of research. 17 , 20 , 21 , 23 , 42 As the population is aging, 1 there will be an increased number of older drivers on the roads. It is therefore a priority to investigate how licensing authorities could benefit from using additional measures of vision, such as contrast sensitivity tests to improve road safety.…”

ObjectivesTo analyze the association between visual impairment and driver self-regulation among a cohort of older drivers waiting for first eye cataract surgery.MethodsNinety-six drivers with bilateral cataract aged 55+ years were assessed before first eye cataract surgery. Data collection consisted of a researcher-administered questionnaire, objective visual measures (visual acuity, contrast sensitivity and stereopsis), a visual attention test (the useful field of view test) and a cognitive test (the Mini-Mental State Examination). Driver self-regulation practices were collected using the Driving Habits Questionnaire and were also measured with an in-vehicle monitoring device. Characteristics of self-regulators and non-self-regulators were compared and a logistic regression model was used to examine the association between 3 objective visual measures and driver self-regulation status.ResultsAfter controlling for potential confounding factors, only binocular contrast sensitivity (p=0.01), age (p=0.03) and gender (p=0.03) were significantly associated with driver self-regulation status. The odds of participants with better contrast sensitivity scores (better vision) self-regulating their driving in at least 1 driving situation decreased (odds ratio [OR]: 0.01, 95% CI: 0.00–0.28) while those of increasing age reported an increased odds of self-regulating their driving (OR: 1.08, 95% CI: 1.01–1.15). The odds of males self-regulating their driving was decreased compared with females (OR: 0.28, 95% CI: 0.09–0.86).ConclusionsWorse binocular contrast sensitivity scores, increasing age and being female were significantly associated with driver self-regulation. The study highlighted that while self-regulation was common among cataract patients, a proportion of those with poor vision did not self-regulate. Further research should determine how cataract patients could benefit from self-regulation strategies while waiting for cataract surgery.

“…On-road evaluation includes explicit instructions by the CDRS on when and where to make turns (e.g., “at the next traffic light, turn left”). Naturalistic driving methods allow for the study of not only crash events but near-crash events, which are similar in terms of driver behavior and vehicle kinematics to actual crashes, yet occur at a rate 2–10 times higher than crash events [ 14 , 15 ], thus creating a larger number of outcome events to analyze in risk factor modeling.…”

“…Older drivers with worse contrast sensitivity had a higher rate of crash and near-crash events [ 21 ], however this finding was based on only 20 drivers. Using the Strategic Highway Research Program 2 (SHRP 2) data [ 13 ], two studies using different analytic approaches both found that impaired contrast sensitivity and peripheral vision were related to elevated rates of collision involvement [ 15 , 22 ]. Also using SHRP 2 data, Guo et al [ 23 ] found that secondary-task-induced distractions posed a greater safety threat for older drivers than for middle-aged drivers, however older drivers were less likely to be engaged in secondary tasks while driving.…”

BackgroundOlder drivers aged ≥70 years old have among the highest rates of motor vehicle collisions (MVC) compared to other age groups. Driving is a highly visual task, and older adults have a high prevalence of vision impairment compared to other ages. Most studies addressing visual risk factors for MVCs by older drivers utilize vehicle accident reports as the primary outcome, an approach with several methodological limitations. Naturalistic driving research methods overcome these challenges and involve installing a high-tech, unobtrusive data acquisition system (DAS) in an older driver’s own vehicle. The DAS continuously records multi-channel video of driver and roadway, sensor-based kinematics, GPS location, and presence of nearby objects in front of the vehicle, providing an objective measure of driving exposure. In this naturalistic driving study, the purpose is to examine the relationship between vision and crashes and near-crashes, lane-keeping, turning at intersections, driving performance during secondary tasks demands, and the role of front-seat passengers. An additional aim is to compare results of the on-road driving evaluation by a certified driving rehabilitation specialist to objective indicators of driving performance derived from the naturalistic data.MethodsDrivers ≥70 years old are recruited from ophthalmology clinics and a previous population-based study of older drivers, with the goal of recruiting persons with wide ranging visual function. Target samples size is 195 drivers. At a baseline visit, the DAS is installed in the participant’s vehicle and a battery of health and functional assessments are administered to the driver including visual-sensory and visual-cognitive tests. The DAS remains installed in the vehicle for six months while the participant goes about his/her normal driving with no imposed study restrictions. After six months, the driver returns for DAS de-installation, repeat vision testing, and an on-road driving evaluation by a certified driving rehabilitation specialist (CDRS). The data streams recorded by the DAS are uploaded to the data coordinating center for analysis.DiscussionThe Alabama VIP Older Driver Study is the first naturalistic older driver study specifically focused on the enrollment of drivers with vision impairment in order to study the relationship between visual dysfunction and driver safety and performance.

Örneğin; yetmiş ve üzeri yaştaki katılımcıların dâhil edildiği bir çalışmada, her iki gözde meydana gelen çevresel görüş kaybının ve zıtlık hassasiyeti azalmasının farklı tip kazalara karışma oranlarında artışa sebep olduğu saptanmıştır (Huisingh et al 2017).

Öz: Trafikte yer alan sürücü gruplarından biri olan yaşlı sürücülerin gelişimsel özellikleri ve deneyimleri ile ilişkili olarak trafikte birtakım özel davranışlar sergilediği görülmektedir. Mevcut çalışmada yaşlı sürücülerin trafikteki bireysel deneyimlerinin kendi bakış açılarından ve kendi ifadeleriyle detaylı biçimde ortaya konulması hedeflenmiştir. Bu amaç doğrultusunda, Ankara ilinde yaşayan, 60 ve üzeri yaştaki 10 erkek katılımcı ile yarı yapılandırılmış görüşmeler gerçekleştirilmiş ve toplanan veriler, yorumlayıcı fenomenolojik analiz yöntemi ile incelenmiştir. Elde edilen bulgulara göre, yaşlı sürücülerin trafikteki deneyimleri yaşla gelen davranış değişikliği, yaşla bağlantılı olumsuz yaşantılar ve duygusal deneyimler, yaşla gelen bilişsel ve fizyolojik değişimler olmak üzere üç üst tema etrafında toplanmaktadır. Yıllar içinde sürücülükte birtakım değişikliklerin meydana geldiği konusunda katılımcıların çoğunun hemfikir olduğu görülmüştür. Yaşlı sürücülerin duygusal deneyimleri, trafiğin yoğun olduğu zorlayıcı durumlarda veya diğer yol kullanıcıları tarafından yapılan saldırgan davranışlara maruz kalın-dığında bazı olumsuzluklar içermektedir. Katılımcıların, kendilerindeki yaşla gelişen fizyolojik ve bilişsel performans düşüşünün farkında oldukları da bulgular arasındadır. Gelecekte yapılması planlanan iyileş-tirme çalışmaları için anlamlı bir zemin hazırlayan araştırma bulguları detaylı bir şekilde sunulmuş ve yorumlanmıştır. Anahtar sözcükler: Yorumlayıcı Fenomenolojik Analiz, Nitel Analiz, Yaşlı Sürücüler, Yaşlı BireylerAbstract: Older drivers display a set of distinct behaviors in traffic in relation to their developmental characteristics and experiences. In the current study, we aim to reveal older drivers' individual experiences in traffic from their perspective and through their expressions. In line with this aim, we conducted semi-structured interviews with 10 male participants aged 60 or older living in Ankara and examined the resultant data through interpretative phenomenological analysis. According to these results, these traffic experiences of older drivers are grouped around three superordinate themes; namely, behavioral changes brought by age, negative incidents and emotional experiences related to age, and cognitive and physiological changes brought by age. According to these results, most participants agreed that they experienced various changes in their driving with age. Emotional experiences of older drivers included several negative consequences under difficult conditions characterized by heavy traffic or when faced with aggressive behavior from other drivers. Another finding was that older drivers were aware that physiological and cognitive performance declines with increasing age. The results, providing a noteworthy base for future intervention programs, are presented and discussed in detail.
