Real-world risk exposure in older drivers with cognitive and visual dysfunction.
Conclusions: Results successfully mapped driver cognitive and visual profiles onto contemporaneous, real-world behavior and risk loci. Results link age-related dysfunction to real-world vehicle control and show that drivers may not sufficiently reduce exposure to higher-risk driving environments. Employing naturalistic observation to monitor and measure patterns of driver behavior can inform methods for early detection of age-related risk, fitness-to-drive assessments, and interventions to preserve safety, mobility, and quality of life in aging or other at-risk populations.

THC-influenced drivers in the new Danish 3-level offense system.
Conclusion: We found that more than two-thirds of the THC offenders faced milder sanctions compared to before the new legislation, suggesting that the new graduated legislation has had a significant impact. The current trend is a steadily increasing number of DUID cases. We believe that the continual increase is caused by a combination of factors, including increased police awareness and training of police personnel along with improved roadside screening abilities.

Frontal crash seat belt restraint effectiveness and comfort accessories used by older occupants.
Conclusions: Accessories placed between the seat back and the lumbar region of an occupant have the potential to increase the risk of submarining due to a change in posture and should be avoided if such a change in posture when seated with an accessory is excessive. Sitting on seat cushions resulted in the greatest increase in seat belt anchor to hip distances and hence largest increase in sternal deflection. Given the fragility, frailty and particular importance of chest injuries among older vehicle occupants, further investigation is needed to determine whether these changes in ATD sternal deflection observed with seat c...

Simulated single-bicycle crashes in the VTI crash safety laboratory.
Conclusions: The study implies that it is possible to examine single-bicycle crashes using crash tests, even though the setup is sensitive to minor input differences and the random variation in the resulting head impact values can be large. Sideway falls with the bicycles standing still were easier to perform with a good repeatability and indicated an influence of seating height on the head impact.

The effect of speed limit reductions in urban areas on cyclists' injuries in collisions with cars.
Conclusions: This study is an important follow-up on the implementation of measures that can influence bicycle safety. The insurance data used, made it possible to quantify a positive effect on injury severity for cyclists in passenger car-to-cyclist collisions when the speed limit was reduced in urban areas. Insurance claims cover collisions of all crash severity, so they include data covering all types of injuries-not just the most severe/fatal ones. This aspect is especially important in the speed intervals evaluated here, since moderate (MAIS 2) injuries are very frequent in lower-speed crashes and even these injuries ...

Comparison across vehicles of passenger head kinematics in abrupt vehicle maneuvers.
Abstract Objective: Studies of vehicle occupant motions in response to abrupt vehicle maneuvers have demonstrated movements that may result in changes in the level of protection for the occupant if a crash subsequently occurs. The previous studies have typically used a single vehicle. The current study assesses whether the patterns of occupant head movement are different across passenger vehicle types.Method: Data collection was conducted on a closed test track with the same driver for all trials.

Seasonal patterns of traumatic brain injury deaths due to traffic-related incidents in the Slovak Republic.
Conclusions: The results show that Slovakia, like many countries, suffers a considerable burden of TBI and that RTIs are a major contributor to this, especially among young adults. Rates of TBI vary by season in Slovakia, and users of different modes of transport appear more or less likely to suffer such injury during different seasons. Considerable variability in rates of injury exists between road users and times of year. Improved understanding of the timing and sufferers of injuries may allow better planning of response and care services. Further research into transport modes and policies aimed at safer driving should b...

Accuracy of algorithms to predict injury severity in older adults for trauma triage.
Conclusion: The results of this study indicate that it is more difficult to accurately predict severe injury in older adults involved in MVCs, which has the potential to result in significant overtriage. This decreased accuracy is likely due to variations in fragility in older adults. These findings indicate that special care should be taken when using regression-based prediction models to determine the appropriate hospital destination for older occupants.

Effect of a Japanese drug alert pictogram on medication-taking/driving behavior.
Conclusion: A pictogram is a potentially useful and effective tool for communicating risk and supporting decision-making by supplying drivers with tailored information. However, we assume that some people who drive frequently must drive for work, go to the hospital, etc. It is essential, in these cases, for medical professionals to be more deeply involved with the patients and to maintain lines of communication by listening to patients' descriptions of their everyday life. By adding these pictograms to the labeling of potentially driver-impairing medications (such as by putting them on the outer packaging, package inserts,...

Pelvis injury risk curves in side impacts from human cadaver experiments using survival analysis and Brier score metrics.
Conclusion: This study underscores the importance of using impulse to describe pelvis injury criteria in lateral impacts. These findings are applicable to anthropomorphic test devices, as matched pair tests are done to determine dummy-based injury criteria/injury assessment risk curves (IARCs). Although IRCs have been developed for WorldSID, it may be appropriate to use impulse-based IARCs. Because THOR is a potential device for automated vehicle environments, it may be appropriate to develop THOR-based IARCS. The present IRCs act as fundamental human-based injury criteria.

The effect of vehicle countermeasures and age on human volunteer kinematics during evasive swerving events.
Conclusion: A pre-pretensioner was an effective vehicle countermeasure during evasive swerving maneuvers as it substantially reduced lateral head and trunk displacement for all age groups. Providing lateral restraint via a sculpted vehicle seat was less effective as the geometry of the torso bolsters when inflated did not provide substantial lateral support.

Prospective assessment of the effectiveness of autonomous emergency braking in car-to-cyclist accidents in France.
Conclusions: This study illustrates the potential benefits and limits of AEB-cyclist systems. High-end systems show acceptable effectiveness rates, but road safety performance strongly depends on external factors such as road surface conditions or has to be tuned in order to avoid unnecessary activations and driver discomfort. Limits of the system's everyday use (lack of maintenance, driver reaction time to collision warnings, etc.) were not taken into account, thus resulting in optimistic evaluations of AEB-cyclist effectiveness.

Effects of alcohol intoxication goggles (fatal vision goggles) with a concurrent cognitive task on simulated driving performance.
Conclusions: Wearing FVG negatively impacted simulated driving performance. However, effects were isolated to specific performance outcomes and were dependent on complexity of the driving task. Addition of a secondary cognitive task exacerbates the effects of FVG on select driving outcomes (i.e. lane position, SDSP), influences the effect direction on other measures (i.e. distance headway), and has a detrimental effect on reaction time to stimuli embedded in the scenario, that is not observed with FVG alone.

The effectiveness of centerline rumble strips (CLRS) on two-lane carriageways in Sweden on injury accident risk for cars equipped with electronic stability control (ESC) and cars without ESC.
Conclusions: Contemporary effectiveness estimates may have important implications for the short and medium-term national road safety management. CLRS remains an important countermeasure to consider for reducing the number of real-world injury crashes. From a systematic safety perspective, it is important to accentuate that CLRS and ESC essentially address different crash scenarios. Still, both CLRS and ESC have the potential to avoid crashes involving unintentional lane drifting resulting in loss of control. When the CLRS alerts a driver of unintentional lane drifting, the ESC can be essential in supporting the driver to s...

Neurocognitive and behavioral markers in DUI recidivists.
Abstract Objective: Driving under the influence (DUI) of alcohol recidivism may be a risk-taking behavior motivated by a change in decision-making capacity.

Does the inclusion of vehicle impoundment in provincial short-term administrative driver's license suspension programs reduce total and alcohol-related fatal collisions in Canada?
Conclusions: While mandatory vehicle impoundment programs for driving in the "warn" range (0.05%-0.08% BAC) have shown success in reducing fatal crashes in British Columbia, similar reductions in two other provinces with short-term vehicle impoundment were not observed.
