Method: Data from an online survey of 844 participants were analyzed using partial least squares structural equation modeling (PLS-SEM).

Results: Perceived usefulness had the strongest direct effect on behavioral intention (0.

A mixed-methods examination of fixed-object crashes among electric utility company fleet vehicles.

Introduction: One of the most common and serious types of crashes among all motor-vehicle users involves collisions with fixed objects. This type of crash occurs frequently among utility vehicle workers while driving for work. The overarching objective of this research was to improve the safety of electric utility company vehicle operators by determining the circumstances under which utility vehicles are involved in crashes with fixed objects and to provide recommendations to help drivers and utility fleet company management prevent these types of crashes.

The Association between Psychological Resilience and Driving Behavior among Older Drivers in Australia.

This study compared a sample of Australian drivers aged 77 years and older to participants from an older driver longitudinal cohort study (Ozcandrive) and examined the relationship between resilience and self-reported driving measures within these samples. Using a survey with a subset of questions from Ozcandrive, data were collected from 237 older drivers throughout Australia. The two samples were analyzed for differences in demographics, health, resilience, and self-reported driving behavior.

Applying systems thinking to improve the safety of work-related drivers: A systematic review of the literature.

Introduction: Light vehicles (<4.5 tons) driven for work purposes represent a significant proportion of the registered motor vehicles on our roads. Drivers of these vehicles have significant exposure to the dangers of the road transport environment.

Examining the contribution of psychological resilience on self-reported and naturalistic driving behavior of older adults.

Introduction: This study examined the contribution of psychological resilience on self-reported driving comfort, abilities, and restrictions, and on naturalistic driving (ND) behavior of older adults at two time points, five years apart (N = 111; Male: 65.8%, Mean age = 86.1 years).

The Influence of Hearing Impairment on Driving Avoidance Among a Large Cohort of Older Drivers.

As people age, some of the commonly experienced psychomotor, visual, and cognitive declines can interfere with the ability to safely drive, often leading to situational avoidance of challenging driving situations. The effect of hearing impairment on these avoidance behaviors has not been comprehensively studied. Data from the American Automobile Association (AAA) Longitudinal Research on Aging Drivers (LongROAD) study were used to assess the effect of hearing impairment on driving avoidance, using three measures of hearing.

Improving Safe Mobility: An Assessment of Vehicles and Technologies among a Large Cohort of Older Drivers.

Evidence suggests that older driver safety may be improved by good vehicle maintenance, in-vehicle advanced technologies, and proper vehicle adaptations. This study explored the prevalence of several measures of vehicle maintenance and damage among older drivers through inspection of their vehicles. We also investigated the prevalence of in-vehicle technologies and aftermarket adaptations.

Potential effects of lowering the BAC limit on injuries, fatalities, and costs.

Introduction: Potential health and cost impacts of lowering the BAC limit for U.S. drivers below .

Perceptions of alcohol-impaired driving and the blood alcohol concentration standard in the United States.

Introduction: Although the number of alcohol-impaired driving (AID) fatalities has declined over the past several years, AID continues to be a serious public health problem. The purpose of this effort was to gain a better understanding of the U.S.

Stakeholder perceptions of lowering the blood alcohol concentration standard in the United States.

Purpose: This study sought to better understand the past change in the legal blood alcohol concentration (BAC) standard from 0.10% to 0.08% in the United States, as well as explore stakeholder perceptions about potential health and other impacts of further lowering the standard below 0.

Characteristics of informal caregivers who provide transportation assistance to older adults.

The study aim was to gain a better understanding of the characteristics of informal caregivers who provide transportation assistance and to explore the types and frequency of this assistance. A telephone survey was administered to a representative sample of 268 informal caregivers (age 45-80) who provide transportation assistance to older adults (age 70 and older) in Michigan. Responses were analyzed overall and by the caregiver sex and care recipient age.

Use, perceptions, and benefits of automotive technologies among aging drivers.

Advanced in-vehicle technologies have been proposed as a potential way to keep older adults driving for as long as they can safely do so, by taking into account the common declines in functional abilities experienced by older adults. The purpose of this report was to synthesize the knowledge about older drivers and advanced in-vehicle technologies, focusing on three areas: use (how older drivers use these technologies), perception (what they think about the technologies), and outcomes (the safety and/or comfort benefits of the technologies). Twelve technologies were selected for review and grouped into three categories: crash avoidance systems (lane departure warning, curve speed warning, forward collision warning, blind spot warning, parking assistance); in-vehicle information systems (navigation assistance, intelligent speed adaptation); and other systems (adaptive cruise control, automatic crash notification, night vision enhancement, adaptive headlight, voice activated control).

Tactical, strategic, and life-goal self-regulation of driving by older adults: development and testing of a questionnaire.

Introduction: Appropriate self-regulation of driving - that is, adjusting one's driving patterns by driving less or avoiding specific situations considered challenging - shows promise as a strategy for extending safe driving. However, results on the extent of self-regulatory practices among older drivers vary considerably across studies.

Method: The purpose of this study was to develop and test a questionnaire to measure self-regulation at multiple levels of driver performance and decision making, using a sample of older drivers comprised of individuals with clinically-determined functional impairments, as well as older adults recruited from the general population.

Increasing self-awareness among older drivers: the role of self-screening.

Introduction: Self-screening by older drivers has shown considerable promise for increasing self-awareness about functional abilities associated with safe driving. The purpose of this study was to improve upon existing self-screening instruments by focusing entirely on "health concerns" that affect driving - that is, the symptoms that people experience due to medical conditions and the medications used to treat them - rather than the medical conditions or medications themselves.

Method: A computer-based, easy-to-use self-screening instrument for older drivers was developed to provide individualized feedback intended to increase self-awareness about declines in driving-related abilities, as well as suggestions for behavioral changes or safety tips to maintain safe driving, further evaluation from a physician/health professional, and vehicle modifications to help compensate for driving-related declines.

Cellular phone use while driving at night.

Objective: Use of a cellular phone has been shown to negatively affect one's attention to the driving task, leading to an increase in crash risk. At any given daylight hour, about 6% of US drivers are actively talking on a hand-held cell phone. However, previous surveys have focused only on cell phone use during the day.

Evaluation of community-based programs to increase booster seat use.

This manuscript reports the results of an evaluation of two community-based booster seat promotion programs in Michigan; one program focused on a low-income community, while the other focused on a Hispanic community. Each community received funding to develop and implement a booster seat intervention program specific to their community. To determine the effectiveness of each program, direct observation surveys of booster seat use were conducted in each community, as well as in similarly composed comparison communities, before and after program implementation.

A direct observation study of nighttime safety belt use in Indiana.

Introduction: Nearly all direct observation studies of safety belt use are conducted exclusively during daylight hours. Recent work has suggested that safety belt use at night may differ from daytime belt use.

Methods: An observational study of nighttime safety belt use, utilizing specialized night vision equipment, was conducted in Indiana surrounding the Click It or Ticket 2006 safety belt mobilization activities.

Driver hand-held cellular phone use: a four-year analysis.

Introduction: The use of hand-held cellular (mobile) phones while driving has stirred more debate, passion, and research than perhaps any other traffic safety issue in the past several years. There is ample research showing that the use of either hand-held or hands-free cellular phones can lead to unsafe driving patterns. Whether or not these performance deficits increase the risk of crash is difficult to establish, but recent studies are beginning to suggest that cellular phone use elevates crash risk.
