The present study aimed to explore the effects of various tactile takeover requests (TORs) (i.e., tactile sliding TOR and traditional vibration TOR) on the takeover performance in an automated driving system.

Preventing Cannabis-impaired driving involves understanding how users assess risk, monitor their use, and plan to get home safely. While extant research has shown substantial heterogeneity in patterns of cannabis use among different user groups, far less research has examined self-regulation among users. The current study aims to identify sub-groups of individuals who used or have used cannabis based on how they perceive risks, monitor their impairment, and plan to avoid driving under the influence of cannabis (DUIC) to examine how the different profiles relate to DUIC outcomes.

In a developing country like India, where the share of motorcyclists is increasing exponentially, their road crashes are also rising at an alarming rate. The majority of these road crashes occur at unsignalized intersections. Therefore, the present study aims to analyze the safety of motorcyclists at unsignalized three-arm intersections under a heterogeneous traffic environment using a fully automated trajectory data extraction tool.

Evaluating the safety risks at unsignalized intersections becomes increasingly complex amid conditions of dense traffic flow, a heterogeneous mix of vehicles, nonadherence to lane demarcations, and reactive driving techniques. Understanding driver behavior under such varying circumstances is crucial for accurately assessing the potential hazards present at these intersections. The study aims to assess the safety of unsignalized intersections by incorporating both spatial and temporal variables under heterogeneous conditions.

The objective of this study is to conduct precise risk prediction of traffic accidents using vehicle trajectory data.

This study aims to explore the role of peer and parental influences on adolescent driving behaviors, particularly concerning distracted and alcohol-impaired driving, in light of the significant number of road accidents and fatalities involving young drivers.

The challenge of combined horizontal and vertical highway alignments continues to be a concern in transportation design, particularly regarding truck stability. This study analyses the stability of trucks on horizontal curves combined with ascending or descending gradients using center of gravity (CoG) height and curve geometry as parameters. It also develops models that predict lateral stability of trucks and criteria for evaluating geometric design consistency based on vehicle stability.

No-apnea questionnaire (NAQ) and STOP-BANG questionnaire (SBQ) are widely used for obstructive sleep apnea (OSA) screening. This investigation aimed to compare the SBQ with the NAQ as an OSA screening tool among commercial drivers.

Since 1998; approximately 1,000 US children have died due to pediatric vehicular heatstroke (PVH; i.e., children overheating in vehicles). As the frequency of cases have largely remained unchanged over time, there is a need for novel research that can inform effective PVH prevention efforts, such as awareness campaigns. The objective of this project was to characterize caregivers' opinions about existing PVH campaigns and thoughts about what future campaigns should look like.

The research aimed to understand the impact of telematics in reducing traffic violations and crashes among drivers working in parcel delivery and the perceived utility, effectiveness, and acceptability of telematics among drivers using them. The objective was to carry out an online survey among drivers who have telematics versus drivers who do not and compare their behaviors in terms of risks and violations controlling for key demographics an exposure.

In recent years, China's motorization process has accelerated, urban road traffic has become increasingly complex, and the safety of children has become increasingly prominent. China aims to encourage the use of child safety seats (CSSs) and stipulates in the Law on the Protection of Minors that "Parents or other guardians of minors take measures, such as equipping child safety seats." However, the utilization rate of such seats in China is still low (<5%, 2021), an important reason is the lack of mandatory legislation. This study focuses on developing cities in China that do not have mandatory legislation on the use of CSS, explores the factors that families support child seat legislation, and explores the impact of children's feedback on the transmission of values within families and the use of CSS in family decisions.

This study compared kinematic and biomechanic responses of the 5 female Hybrid III in the right-rear and right-front passenger seats in frontal NCAP tests with 2015-16 MY vehicles. It focused on the lap-shoulder belt restraint of the rear passenger.

This study aims to address the limitations of using historical crash data and trajectory data for crash and conflict identification. Specifically, it focuses on enhancing real-time conflict identification by investigating the influence of traffic flow state variables and their interactions on conflicts.

Distracted driving is a primary contributor to for motor vehicle crashes, the leading cause for injuries and fatalities for youth. Although attention and working memory clearly underlie driving abilities, few studies explore these functions on the brain-level under the cognitive load of driving. To understand the load driving has on auditory attention processing, we examined the differences in dynamic brain response to auditory stimuli during LOAD (while driving in a high-fidelity driving simulator) and No-LOAD conditions (seated in simulator, parked on the side of the road).

The overwhelming majority of teenage driving research in the US is framed around characteristics associated with risk, rather than factors that promote safety. In this study, we examine the role of purpose in life and mindfulness as two factors that may be associated with safer driving behaviors.

The objective of this study is to examine the effects of seatback angle, seat rotation, and impact speed on occupant kinematics and injury risk in highly automated vehicles.

The first objective was to evaluate the effect of using less censored (i.e., exact and interval-censored) data on thoracic injury risk curves and the resulting injury probabilities. The second objective was to generate new injury risk curves to predict Abbreviated Injury Scale (AIS) 3+ rib fractures based on chest deflection.

This study quantified the local fracture tolerance of the distal fibula. The purpose of this data is to refine the understanding of ankle fracture tolerance in the population and enhance injury prediction by computational tools.

Varying initial belt torso contact (i.e., belt gap) on belt-positioning boosters may have implications for potential shoulder belt slip-off in low-speed evasive vehicle maneuvers and differences in dynamic outcomes in frontal sled tests. This study evaluated the influence of initial booster belt gap and belt fit conditions on the kinematic and kinetic outcomes during frontal oblique impacts.

The objective of this study was to compare drink driving and related road safety issues in 2 urban areas of 6 countries and develop an equation for estimating the rate of crash underreporting to the police in urban areas of countries that lack this information.

In 2022; South Korea had 3.3 million daily bicycle users and around 13,000 crashes with 190 fatalities annually. While helmets are known to prevent head injuries, research on their effectiveness in preventing fatalities is lacking. This study explores factors influencing bicycle-related fatalities and examines if helmets reduce the risk of death in road traffic incidents.
