简要总结
The tech-wise driver: Exploring the sustained efficacy and technology acceptance of targeted ADAS for older drivers A significant percentage of road traffic fatalities registered in Canada occurred among older adults. According to the studies, the Advanced Driver Assistance Systems (ADAS) can enhance the safety and mitigate the age-related declines of older drivers. Whether sustained use results in declines in driving performance in older drivers relying on ADAS remains largely unexplored. This is problematic given emerging evidence on ADAS use by older drivers. Furthermore, exploring changes in ADAS technology acceptance in relation to sustained use can inform the correlation between perceived safety and intention to use.
The investigators hypothesize that, compared to driving simulator training alone, lane departure warning (LDW), cruise control (CC), and forward proximity warning (FPW) technology will result in a sustained decrease of critical driving errors in this population; and that exposure to the technology will increase participants' perceived usability and ease of use. To achieve this goal, the investigators will explore the determination of sustained efficacy, establish the impact of technology exposure, evaluate the concurrent validity of a computerized model of driving error type and severity using trained occupational therapy in-vehicle evaluation as the criterion, when evaluating older drivers 'performance.
Our findings may significantly impact the ability of older drivers to choose in-vehicle technologies, and our study will be the first to assess the criterion validity of a simulator-derived computerized model against the findings of an evaluator-based functional assessment.
详细描述
The driving simulator will be used to collect data on drivers in driving scenarios that include situations that may be more challenging for some drivers, e.g., pedestrian stepping into a crosswalk, a vehicle pulling out of a parking spot, a vehicle suddenly changing lanes. Vehicle data and gaze data will be collected for drivers along with images from the simulated environment. The simulator will measure driving performance through metrics generated from the simulator, e.g. pedal (i.e., gas and brake) reaction time, vehicle velocity, headway distance/time, etc.
Participants: Licensed older drivers (≥65 years of age) will be included in this study. Participants will be excluded if they have neurological or psychiatric conditions that would preclude full participation in driving activity, or if they take medications that may have a sustained negative impact on their mental and/or physical functioning during driving.
Sample Size: A sample size of n=68 will be recruited to achieve 80% power to detect a medium effect size of .50 based on a two-sided significance test with a significance level of 0.05.
Procedure:
- Interested potential participants will reach to the team, using the information distributed during recruitment.
- Upon confirm eligibility criteria, the first session will be scheduled.
- Participants will receive a parking pass to park on the premises.
- The first session will take approximately 1 hr to complete.
- The objective of the study will be reviewed with each participant and they will be shown the simulator.

盲法说明
Masking, also known as blinding, refers to the practice of concealing information about the intervention assignment from certain parties involved in a study to reduce bias. In the described study, the masking applies to the Outcomes Assessor, who is an independent blinded occupational therapist responsible for evaluating the driving performance of participants. This means that the Outcomes Assessor will not be aware of which group (ADAS-integrated driver simulation training or driving-simulator training alone) each participant belongs to during the assessment process, helping to ensure an unbiased evaluation of the study outcomes.

结局指标
主要结局
Number of driving errors
时间窗: The study will span over a 12-week period, encompassing pre-test, post-test 1, and post-test 2 assessments.
This outcome aims to assess the sustained efficacy of a targeted Advanced Driver Assistance Systems (ADAS) intervention comprising Lane Departure Warning (LDW), Cruise Control (CC), and Forward Proximity Warning (FPW) technologies on the driving performance of older drivers (≥65 years). The study compares the performance of participants who receive ADAS-integrated driver simulation training against those who undergo driving-simulator training alone. The primary focus is on measuring the decrease in critical driving errors, as evaluated by an independent blinded occupational therapist, across post-test intervals.
Type of driving errors
时间窗: The study will span over a 12-week period, encompassing pre-test, post-test 1, and post-test 2 assessments.
The blinded evaluator will record type pf driving errors, to establish if there is a decrease in the number of critical driving errors (i.e. those requiring physical intervention from an instructor).
