Factors related to the low-risk perception of driving after cannabis use
This study identified sociodemographic characteristics, substance use, other driving behaviors, peer norms, and psychological characteristics that are associated with lower risk perception regarding DACU.METHODS: Canadian drivers aged 17-35 who have used cannabis in the past year (n = 1,467) completed an online questionnaire. A multivariate linear regression model allowed for identifying variables associated with the low-risk perception of DACU (i.e. believing it to be safe as one's driving ability is not impaired by cannabis or by being high).RESULTS: Lower risk perception of DACU was associated with identifying as male, ...

Gaze entropy metrics for mental workload estimation are heterogenous during hands-off level 2 automation
Accid Anal Prev. 2024 Apr 26;202:107560. doi: 10.1016/j.aap.2024.107560. Online ahead of print.ABSTRACTAs the level of vehicle automation increases, drivers are more likely to engage in non-driving related tasks which take their hands, eyes, and/or mind away from the driving task. Consequently, there has been increased interest in creating Driver Monitoring Systems (DMS) that are valid and reliable for detecting elements of driver state. Workload is one element of driver state that has remained elusive within the literature. Whilst here has been promising work in estimating mental workload using gaze-based metrics, the lit...

Injury risk curves to guide safe speed limits on Swedish roads using German crash data supplemented with estimated non-injury crashes
Accid Anal Prev. 2024 Apr 25;202:107586. doi: 10.1016/j.aap.2024.107586. Online ahead of print.ABSTRACTVision Zero postulates that no one should be killed or seriously injured in road traffic; therefore, it is necessary to define evidence-based speed limits to mitigate impact severity. The overall aims to guide the definition of safe speeds limits by establishing relations between impact speed and the risk of at-least-moderate (MAIS2+) and at-least-severe (MAIS3+) injuries for car occupants in frontal and side crashes in Sweden. As Swedish in-depth data are unavailable, the first objective was to assess the applicability o...

Hazard warning modalities and timing thresholds for older drivers with impaired vision
CONCLUSIONS: While early warnings improved hazard responses and reduced collisions for ICS participants, late warnings did not, resulting in high collision rates. In contrast, both early and late warnings were helpful for NV drivers. Non-directional-tactile warnings were the most effective in reducing collisions. The findings provide insights relevant to the development of hazard warnings tailored for drivers with impaired vision.PMID:38669900 | DOI:10.1016/j.aap.2024.107599 (Source: Accident; Analysis and Prevention.)

Deciding when to cross in front of an autonomous vehicle: How child and adult pedestrians respond to eHMI timing and vehicle kinematics
Accid Anal Prev. 2024 Apr 25;202:107567. doi: 10.1016/j.aap.2024.107567. Online ahead of print.ABSTRACTHow autonomous vehicles (AVs) communicate their intentions to vulnerable road users (e.g., pedestrians) is a concern given the rapid growth and adoption of this technology. At present, little is known about how children respond to external Human Machine Interface (eHMI) signals from AVs. The current study examined how adults and children respond to the combination of explicit (eHMI signals) and implicit information (vehicle deceleration) to guide their road-crossing decisions. Children (8- to 12-year-olds) and adults made...

Modeling temporal correlation and heterogeneity in real-time conflict rates using Bayesian Tobit models for signalized intersections
The objective of this study is to develop real-time traffic conflict rates models simultaneously accommodating temporal correlation and unobserved heterogeneity across observations. Signal cycle level traffic data, including traffic conflicts, traffic and shock wave characteristics, collected from six signalized intersections were used. Three types of Tobit models: conventional Tobit model, temporal Tobit (T-Tobit) model, and temporal grouped random parameters (TGRP-Tobit) model were developed under full Bayesian framework. The results show that significant temporal correlations are found in T-Tobit models and TGRP-Tobit m...

Analysis and regulation of driving behavior in the entrance area of freeway tunnels: Implementation of visual guidance systems in China
Accid Anal Prev. 2024 Apr 24;202:107600. doi: 10.1016/j.aap.2024.107600. Online ahead of print.ABSTRACTIn China, visual guidance systems are commonly used in tunnels to optimize the visual reference system. However, studies focusing specifically on visual guidance systems in the tunnel entrance area are limited. Hence, a driving simulation test is performed in this study to quantitatively evaluate the effectiveness of (i) visual guidance devices at different vertical positions (pavement and roadside) and (ii) a multilayer visual guidance system for regulating driving behavior in the tunnel entrance area. Furthermore, the c...

Safety performance of dedicated and preferential bus lanes using multivariate negative binomial models for Bogot á, Colombia
Accid Anal Prev. 2024 Apr 24;202:107595. doi: 10.1016/j.aap.2024.107595. Online ahead of print.ABSTRACTPublic transport priority systems such as Bus Rapid Transit (BRT) and Buses with High Level of Service (BHLS) are top-rated solutions to mobility in low-income and middle-income cities. There is scientific agreement that the safety performance level of these systems depends on their functional, operational, and infrastructure characteristics. However, there needs to be more evidence on how the different characteristics of bus corridors might influence safety. This paper aims to shed some light on this area by structuring ...
