An Examination of Two Diverse Communities: Residents' Transportation Behaviors, Challenges, and Opportunities.

The Smart Cities Collaborative aims to mitigate transportation challenges and inequities with new approaches and technologies (e.g., ridesharing). Therefore, assessing community transportation needs is essential. The team explored the travel behaviors, challenges, and/or opportunities among low- and high-socioeconomic status (SES) communities. Using Community-Based Participatory Research principles, four focus groups were conducted to investigate residents' behaviors and experiences with transportation availability, accessibility, affordability, acceptability, and adaptability. Focus groups were recorded, transcribed, and verified before thematic and content data analysis. Participants with low SES (n = 11) discussed user-friendliness, uncleanliness, and bus accessibility challenges. Comparatively, the participants with high SES (n = 12) discussed traffic congestion and parking. Both communities had concerns about safety and limited bus services and routes. Alternatively, opportunities included a convenient fixed-route shuttle. All groups stated the bus fare was affordable unless multiple fares or rideshare were needed. Findings provide valuable insight when developing equitable transportation recommendations.

Does in-vehicle automation help individuals with Parkinson's disease? A preliminary analysis.

Introduction: PD is a progressive neurodegenerative disorder that affects, according to the ICF, body systems (cognitive, visual, and motor), and functions (e.g., decreased executive functions, decreased visual acuity, impaired contrast sensitivity, decreased coordination)-all which impact driving performance, an instrumental activity of daily living in the domain of "Activity" and "Participation" according to the ICF. Although there is strong evidence of impaired driving performance in PD, few studies have explored the real-world benefits of in-vehicle automation technologies, such as in-vehicle information systems (IVIS) and advanced driver assistance systems (ADAS), for drivers with PD. These technologies hold potential to alleviate driving impairments, reduce errors, and improve overall performance, allowing individuals with PD to maintain their mobility and independence more safely and for longer periods. This preliminary study aimed to fill the gap in the literature by examining the impact of IVIS and ADAS on driving safety, as indicated by the number of driving errors made by people with PD in an on-road study. Methods: Forty-five adults with diagnosed PD drove a 2019 Toyota Camry equipped with IVIS and ADAS features (Toyota Safety Sense 2.0) on a route containing highway and suburban roads. Participants drove half of the route with the IVIS and ADAS systems activated and the other half with the systems deactivated. Results: The results suggest that systems that assume control of the driving task, such as adaptive cruise control, were most effective in reducing driving errors. Furthermore, individual differences in cognitive abilities, particularly memory, were significantly correlated with the total number of driving errors when the systems were deactivated, but no significant correlations were present when the systems were activated. Physical capability factors, such as rigidity and bradykinesia, were not significantly correlated with driving error. Discussion: Taken together, these results show that in-vehicle driver automation systems can benefit drivers with PD and diminish the impact of individual differences in driver cognitive ability.

Librarian and Researcher Assessments of Search Result Relevance: How Well Do They Align?

Conducting comprehensive but efficient literature searches for complex evidence syntheses involves selecting databases that will retrieve the greatest number of relevant results on the question. Lack of a comprehensive single database on allied health educational topics challenges those seeking such literature. In this study, six participants contributed research questions on instructional methods and materials for allied health patients, caregivers, and future health professionals. Two health sciences librarians created search strategies for these questions and searched eleven databases. Both the librarians and the six participants evaluated the search results using a rubric based on PICO to assess extent of alignment between the librarians' and requestors' relevance judgments. Intervention, Outcome, and Assessment Method constituted the most frequent bases for assessments of relevance by both librarians and participants. The librarians were more restrictive in all of their assessments except in a preliminary search yielding twelve citations without abstracts. The study's results could be used to identify effective techniques for reference interviewing, selecting databases, and weeding search results.

RCT protocol for driving performance in people with Parkinson's using autonomous in-vehicle technologies.

Introduction: Driving is an essential facilitator of independence, community participation, and quality of life. Drivers with Parkinson's Disease (PD) make more driving errors and fail on-road evaluations more than healthy controls. In-vehicle technologies may mitigate PD-related driving impairments and associated driving errors. Establishing a rigorous study protocol will increase the internal validity and the transparency of the scientific work. Methods: We present a protocol to assess the efficacy of autonomous in-vehicle technologies (Level 1) on the driving performance of drivers with PD via a randomized crossover design with random allocation. Drivers with a PD diagnosis based on established clinical criteria (N = 105), referred by neurologists, are exposed to two driving conditions (technology activated or not) on a standardized road course as they drove a 2019 Toyota Camry. The researchers collected demographic, clinical, on-road data observational and kinematic, and video data to understand several primary outcome variables, i.e., number of speeding, lane maintenance, signaling, and total driving errors. Discussion: The protocol may enhance participant adherence, decrease attrition, provide early and accurate identification of eligible participants, ensure data integrity, and improve the study flow. One limitation is that the protocol may change due to unforeseen circumstances and assumptions upon implementation. A strength is that the protocol ensures the study team executes the planned research in a systematic and consistent way.Following, adapting, and refining the protocol will enhance the scientific investigation to quantify the nuances of driving among those with PD in the era of automated in-vehicle technologies. Trial registration: ClinicalTrials.gov NCT04660500.

Rater-Reliability of Assessing Driving Errors with a DriveSafety 250 Simulator.

This study aimed to establish inter-rater reliability among three raters while training new driver rehabilitation specialists to correctly identify driving errors on a DriveSafety 250 driving simulator. Five participants completed adaptation, residential and suburban, and city and highway scenarios. Intraclass correlation coefficients indicated scores between .623-.877 (p = .003-.122) for the total driving errors recorded in the two scenario drives with rater agreement initially ranging between 7-8%. When analyzing the data for types of driving errors, the intraclass correlation coefficients ranged from .556-.973 (p < .05) and rater agreement between 15-100%. Through proper training and strategy development, raters reached 100% consensus on all aspects of inter-rater reliability while assessing driving errors.

Fidelity of a Traffic Safety Education Intervention for Combat Veterans.

Equipoise, feasibility, and fidelity were studied for the control condition of an occupational therapy driving intervention in a randomized controlled trial. We ranked equipoise and feasibility of six traffic safety education methods and created an implementation fidelity competency checklist. Education method selection was informed using the proportion of concordant ranks analysis while literature and a peer review informed competency checklist development. A proctored-online course delivery had the highest rater agreement (equipoise = .96 [.87-1.00]; feasibility = .99 [.97-1.00]). Implementation fidelity was supported by a 19-component training and evaluation checklist. This study supports promoting the scientific rigor of the RCT via - equipoise, feasibility, and implementation fidelity.

Driving Outside the Wire: Examining Factors Impacting Veterans' Postdeployment Driving.

Combat Veterans (CVs) deployed to Iraq or Afghanistan experience driving difficulty, based on medical conditions and/or deployment exposures, elevating their risk of motor vehicle crash-related injury or death. To address grounded theory rigor and incorporate constructs such as the Person Environment Occupation Performance model, we revised the Hannold et al. (2013) conceptual framework. We conducted two focus groups with seven CVs. Conceptual framework revisions were based on an iterative process and thematic analysis. We elicited CVs' perspectives on deployment training, driving pre- and postdeployment, strategies, and intervention preferences. Personal, environmental, and task factors underpinned CVs' driving. Participants described triggers (e.g., stressful stimuli), use of environmental (e.g., car controls) or personal (e.g., avoiding traffic) strategies, and outcomes of appropriate or risky driving. Findings illustrated CVs' driving difficulty and informed development of a Veteran-centric driving intervention. Improving driving fitness has implications for Veterans' participation and community integration.

Smart In-Vehicle Technologies and Older Drivers: A Scoping Review.

In-vehicle technologies may decrease crash risk in drivers with age-related declines. Researchers determined the impact of in-vehicle information systems (IVIS) or advanced driving assistance systems (ADAS) on driving. Through a scoping review, the effect of IVIS or ADAS on older drivers' convenience (i.e., meets one's needs), comfort (i.e., physical or psychological ease), or safety (i.e., absence of errors or crashes) was examined. Researchers synopsized findings from 28 studies, including driving simulators and on-road environments. Findings indicated that IVIS or ADAS enhanced safety and mitigated age-related declines. Notably, IVIS may reduce cognitive workload, but may jeopardize safety if the systems are overly complicated. The ADAS enhanced safety and comfort by increasing speed control, lane maintenance, and braking responses. However, no studies addressed convenience. In-vehicle technologies may enhance safety and comfort while driving, if one's cognitive workload is not compromised. Naturalistic studies are needed to elucidate the risks and benefits of IVIS and ADAS for older drivers.
