Drivers’ Hazard Avoidance During Vehicle Automation: Impact Of Mental Models And Implications For Training, Ganesh Pai Mangalore Mar 2024

Drivers’ Hazard Avoidance During Vehicle Automation: Impact Of Mental Models And Implications For Training, Ganesh Pai Mangalore

Doctoral Dissertations

Advanced Driver Assistance Systems (ADAS) are vehicle automation systems that have become more accessible and prevalent in vehicles in recent years. But the introduction of such technologies introduces new human factors challenges. Past literature suggests that users of vehicle automation lack the necessary and appropriate knowledge about their automation system. This may play a negative role in their hazard avoidance abilities when driving with automation features. Improving mental models and knowledge could generally lead to safer interactions with vehicle automation systems, but any effort to develop hazard avoidance skills when driving with vehicle automation is impeded by the lack of …


Improving Young Driver Perceptions Of Vulnerable Road Users Through A Persuasive Intervention, Shashank Mehrotra Mar 2022

Improving Young Driver Perceptions Of Vulnerable Road Users Through A Persuasive Intervention, Shashank Mehrotra

Doctoral Dissertations

Vulnerable road users (VRUs), including bicyclists, pedestrians, and road users of other modalities, are at a higher risk of collision with young drivers when a complex traffic situation presents itself. Past research has established the importance of young drivers’ perceptions about VRUs that would encourage safe behavior. This research designed and evaluated a novel persuasive intervention that can help improve the perceptions of young drivers while they interact with VRUs. The study identified young drivers’ perceptions towards VRUs who have been licensed in the past 12 to 18 months through structured interviews. Based on these findings, an interactive intervention was …


Comparing And Improving The Design Of Physical Activity Data Visualizations, Peter M. Frackleton Oct 2021

Comparing And Improving The Design Of Physical Activity Data Visualizations, Peter M. Frackleton

Masters Theses

Heart disease is a leading cause of death in the United States, and older adults are at highest risk of being diagnosed with heart disease. Consistent physical exercise is an effective means of deterring onset of heart disease, and physical activity tracking devices can inspire greater activity in older adults. However, physical activity tracking device abandonment is quite common due to limitations on what can be learned from the activity data that is collected. Better data visualization of physical data presents an opportunity to surpass these limitations. In this thesis, a task-based human subject study was performed with three different …


Factors Affecting Drivers’ Off-Road Glance Behavior While Interacting With In-Vehicle Voice Interfaces – Insights From A Secondary Data Analysis, Fangda Zhang Sep 2021

Factors Affecting Drivers’ Off-Road Glance Behavior While Interacting With In-Vehicle Voice Interfaces – Insights From A Secondary Data Analysis, Fangda Zhang

Doctoral Dissertations

Given the prevalence of in-vehicle technologies and the critical role of visual attention plays in driving safety, this dissertation work aimed to fill the research gap that 1) little was known about the visual demands associated with a driver engaging with in-vehicle voice interfaces; 2) the concurrent effect of interacting with in-vehicle voice interfaces and other commonly discussed individual-level factors has barely been targeted. This research work was a secondary data analysis based on a large-scale field experiment wherein 144 participants had been recruited and driven a test vehicle while performing a series of tasks using voice-based interfaces. Pre- and …


Improving Drivers’ Behaviour When Partial Driving Automation Fails, Yalda Ebadi Dec 2020

Improving Drivers’ Behaviour When Partial Driving Automation Fails, Yalda Ebadi

Doctoral Dissertations

With the advent of automated vehicle systems, the role of drivers has changed to a more supervisory role. However, it is known that all vehicles with Level 2 (L2) systems have a very specific operational design domain (ODD) and can only function on limited conditions. Hence, it is important for drivers to perceive the situations properly and regain the control from the L2 system when needed. As suggested by past research, designing an informative interface could help drivers in their new supervision and intervention role while driving with L2 vehicles by providing feedback to drivers when hazards or event that …


Evaluation And Validation Of Distraction Detection Algorithms On Multiple Data Sources, Shashank Mehrotra Oct 2018

Evaluation And Validation Of Distraction Detection Algorithms On Multiple Data Sources, Shashank Mehrotra

Masters Theses

This study aims to evaluate algorithms designed to detect distracted driving. This includes the comparison of how efficiently they detect the state of distraction and likelihood of a crash. Four algorithms that utilize measures of cumulative glance, past glance behavior, and glance eccentricity were used to understand the distracted state of the driver and were validated on two separate data sources (i.e., simulator and naturalistic data). Additionally, an independent method for distraction detection was designed using data mining methods. This approach utilized measures like steering degree, lane offset, lateral and longitudinal velocity, and acceleration. The results showed a higher likelihood …


Evaluation Of A Training Program (Strap) Designed To Decrease Young Drivers Secondary Task Engagement In High Risk Scenarios, Akhilesh Krishnan Nov 2015

Evaluation Of A Training Program (Strap) Designed To Decrease Young Drivers Secondary Task Engagement In High Risk Scenarios, Akhilesh Krishnan

Masters Theses

Distracted driving involving secondary tasks is known to lead to an increased likelihood of being involved in motor vehicle crashes. Some secondary tasks are unnecessary and should never be performed. But other secondary tasks, e.g., operating the defroster, are critical to safe driving. Ideally, the driver should schedule when to perform the critical tasks such that the likelihood of a hazard materializing is relatively small during the performance of the secondary task. The current study evaluates a training program -- STRAP (Secondary Task Regulatory & Anticipatory Program) -- which is designed to make drivers aware of latent hazards …


Investigating Teenage Drivers' Driving Behavior Before And After Lag (Less Aggressive Goals) Training Program, Jingyi Zhang Nov 2014

Investigating Teenage Drivers' Driving Behavior Before And After Lag (Less Aggressive Goals) Training Program, Jingyi Zhang

Masters Theses

Motor vehicle crashes are a leading cause of death during adolescence, with the fatal crash rate per mile-driven for 16-19 years old drivers being nearly 3 times larger than the rate for drivers age 20 and older. High gravitational events among teenage drivers, such as quick starts, and hard stops, have been shown to be highly correlated with crash rates. The current younger driver training programs developed in the late 1990s, however, do not appear to be especially effective in regard to many skills which are critical to avoiding crashes. With this in mind, a simulator-based training program aimed at …


The Effect Of External Distractions On Novice And Experienced Drivers' Anticipation Of Hazards And Vehicle Control, Gautam Divekar Jan 2011

The Effect Of External Distractions On Novice And Experienced Drivers' Anticipation Of Hazards And Vehicle Control, Gautam Divekar

Masters Theses 1911 - February 2014

Out-of-vehicle distractions were identified as contributing factors to about 29.4 % of all crashes that were reported between the years 1995 to 1999 (Stutts J. K., 2005; Stutts J. R., 2001).These crash statistics are from a decade ago. With the increase of cars, pedestrians, shops,vendors, billboards and signs over the last decade it can be safely assumed that the driving environment is more complex now and has greater potential for external driver distraction. Given this, it is important to know the effects of out-of-vehicle distraction on drivers’ ability to drive safely in their presence. With this in mind, a driving …
