Analyzing traffic violations among motorcyclists using structural equation modeling
This article aims to identify the role of seven factors on traffic violations, including motorcyclist characteristics, road conditions, environmental circumstances, riding skills, cycling statuses, motorcycle age and previous negative experiences such as fines and accidents. The structural equation modeling was applied to evaluate the impact of these factors pertinent to motorcyclists' crashes. To assess these factors, 600 motorcyclists have been interviewed in Kerman, Iran. The results indicated that motorcyclists' characteristics are the most effective factor in violation commitment. Since most motorcyclists are young, w...

Healthcare costs of road injuries in Saudi Arabia: A quantile regression analysis
Accid Anal Prev. 2021 Jul 2;159:106266. doi: 10.1016/j.aap.2021.106266. Online ahead of print.ABSTRACTBACKGROUND: Road traffic injuries (RTIs) are the second leading cause of death in Saudi Arabia. Their economic burden is significant but poorly quantified, as limited literature exists locally. We aim to estimate the impact of RTIs on healthcare costs.METHODS: We included all patients from the hospital's trauma registry for the year 2017 (n = 381). Due to the availability of data, the analysis focused only on direct medical costs incurred during the hospitalization period. We computed the components of hospitalization cost...

Evaluating automated emergency braking performance in simulated car-to-two-wheeler crashes in China: A comparison between C-NCAP tests and in-depth crash data
Accid Anal Prev. 2021 Jul 2;159:106229. doi: 10.1016/j.aap.2021.106229. Online ahead of print.ABSTRACTAutomated Emergency Braking (AEB) is an effective way to prevent crashes from happening or mitigate their severity. Because riders of two-wheelers (TWs) are among the most vulnerable road users, New Car Assessment Programs, like the China New Car Assessment Program (C-NCAP), have recently introduced test scenarios for the assessment of AEB for cars encountering TWs (TW-AEB). The main aim of this study was to determine how well two different C-NCAP test scenario datasets reflect real-world crash scenarios for the purpose of...

Obstacles and risks in the traffic environment for users of powered wheelchairs in Sweden
CONCLUSIONS: There are still major challenges with regard to preventing obstacles and risks in the traffic environment for PWC users. To discern PWC users in traffic accident and injury data bases, a start would be to register type of aid used for persons involved in an accident. Furthermore, to emphasise PWC users' role as VRUs, it may also be advantageous to describe them as drivers rather than users when navigating the traffic environment. Given the limited sample, further research covering more data from a broader perspective would be beneficial. By incorporating emerging knowledge of PWC users' prerequisites and needs...

Incorporating multiple congestion levels into spatiotemporal analysis for the impact of a traffic incident
Accid Anal Prev. 2021 Jul 2;159:106255. doi: 10.1016/j.aap.2021.106255. Online ahead of print.ABSTRACTTraffic incidents occurring on the road interrupt the smooth mobility of traffic flow and lead to traffic congestion. Although there has been a proliferation of studies that attempt to estimate the spatiotemporal impact of a traffic incident, most, if not all, of them focus exclusively on the differentiation of bi-level traffic status. In this research, we propose to incorporate multiple congestion levels in the spatiotemporal analysis for the impact of a traffic incident, which is new to the literature. The input to our m...

Development of crash modification factors for roadway illuminance: A matched case-control study
This study aimed to investigate the relationship between nighttime crash risk and two critical photometric criteria, i.e., average lighting level and uniformity. To achieve this goal, high-resolution horizontal illuminance data were collected in Florida for 300 + center-miles from 2011 to 2014. Based on the data, a matched case-control study was conducted to address two major issues existing in previous studies: (1) the confounding effects of illuminance standard deviation on illuminance mean and (2) spatially-unrelated extreme values for ratio-based uniformity. By eliminating the confounding effects through a random match...

Exploring transition durations of rear-end collisions based on vehicle trajectory data: A survival modeling approach
This study proposes a novel approach in rear-end collision risk analysis based on the concept of transition durations. The vehicle trajectory data were extracted and the TTC index was used to identify risky and safe conditions. Three important transition durations are defined and their rationalities for evaluating rear-end collision risks are examined by developing random-parameters accelerated failure time (AFT) survival models. Furthermore, a typical case from real trajectory data is taken to discuss the limitations of using TTC and its variants, and the advantage of the proposed transition durations. The results of rand...

What drives people to use automated vehicles? A meta-analytic review
This study investigated the underlying mechanisms for AV acceptance and how the mechanisms differed across subgroups by reviewing and synthesizing existing literature. We proposed AV acceptance models by extending the basic Technology Acceptance Model (TAM) with trust and perceived risk factors. Data from 36 studies were extracted to fit the models using meta-analytic structural equation modeling technique. The results suggested that trust contributed most in determining AV acceptance, followed by perceived usefulness and perceived risk, and perceived ease of use makes the least contribution. The subgroup analyses showed t...

Analysis of ebike dynamics and cyclists' anxiety levels and interactions with road vehicles that influence safety
This study suggests that dense traffic in the afternoon and the demands of riding a bike in complex traffic conditions result in a higher mental workload even though cyclists slowed down their speeds. Furthermore, the majority reported perceived risks of cycling on a shared road with other vehicles regardless of the demographic differences. The findings from this study can be used as a framework for the development of active safety features for ebikes.PMID:34214914 | DOI:10.1016/j.aap.2021.106272 (Source: Accident; Analysis and Prevention.)

Perceived effects of cannabis and changes in driving performance under the influence of cannabis
CONCLUSIONS: Overall, some of the effects perceived by the driver were better related to changes in driver inputs rather than the presence of cannabis itself. Changes in performance measures such as SDLP are better explained by dosing condition. Thus, driver's perceptions may result in changes to driving behavior that could mitigate the effect of cannabis. For both lateral and longitudinal control, an increasing perception of stimulation produced a positive effect on performance.

Time and temperature sensitivity of the hybrid III lumbar spine
CONCLUSIONS: A modest decrease in temperature can be sufficient to dramatically change the response and repeatability of the lumbar HIII component in compressive loading. The large magnitude of the temperature effect has severe implications in its ability to overwhelm the contributions of targeted test variables. These findings highlight the importance of controlling, monitoring and reporting temperature conditions during HIII testing, even in indoor laboratory environments.PMID:34180741 | DOI:10.1080/15389588.2021.1908543 (Source: Traffic Injury Prevention)
