The present study aims to examine the impact of such distractions using experimental data employing the Vienna Test System (VTS). Eighty drivers (70% male, 30% female) from mixed traffic environments participated, resulting in 240 data samples across two age groups (young and mature). Reaction time was assessed under three conditions: (i) Normal, (ii) Music, and (iii) Call using the VTS, which includes visual and auditory stimuli requiring physical reactions, thus closely simulating real-life driving scenarios. Results showed that male drivers’ reaction time increased by 4.8% and 20.1% under Music and Call conditions, respectively, while female drivers exhibited increases of 6.1% and 13.5%, respectively. The comparison of reaction time among young and mature groups under each condition indicated that Call distractions led to the highest increase (12.0%) in reaction time, followed by Normal (10.8%) and Music (8.3%). A second-degree polynomial equation was proposed to estimate reaction time from age. Additionally, the Weibull Accelerated Failure Time (AFT) model identified key factors affecting reaction time under normal conditions, resulting in a formulated mathematical expression.

While some studies have employed vehicle trajectory data to simulate and investigate microscopic merge behavior, most have failed to consider the interaction between vehicles and have not fully investigated the factors that influence merge risk using vehicle trajectory data. This study considers the interactions between vehicles during the merging process and, based on a “competitive-cooperative” driving mode perspective, proposes a new method for classifying vehicle merging behavior modes in merging zones. It also explores the differences in risk levels and influencing factors between different merging modes. Using aerial-captured merging vehicle trajectory data, and based on previous research and actual observations, merging behaviors are classified into free, homeostatic, competitive, and cooperative modes (FM, HM, CmM, and CoM) according to the gap distance and microscopic interaction between vehicles before and after merging. The lane change risk index (LCRI) is introduced as an alternative safety measure to assess the risk of merging vehicle groups. The k-means algorithm is used to classify the LCRI, and a separate ordered logit model is constructed for each merging behavior mode. The modeling results indicate that classification modeling performs better than all data modeling, and the risk level of merging vehicle groups is closely related to the motion state of the merge vehicle, the average and standard deviation of the longitudinal speed difference between vehicles, and the gap distance between vehicles. The risk levels of the four merging modes and their influencing factors differ, with FM having the lowest risk, followed by CoM, HM having a higher risk, and CmM having the highest risk. The study results provide an in-depth analysis of merge zone risk factors, offering a theoretical basis for improving traffic safety management measures.</div></div>","PeriodicalId":6926,"journal":{"name":"Accident; analysis and prevention","volume":"220 ","pages":"Article 108153"},"PeriodicalIF":5.7,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144489629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We hypothesize that the passengers’ experience in different WS performance criteria—visibility, legibility, consistency, and correctness—affect passengers’ perceived reliability of it, which, by virtue of the Halo Effect, subsequently influences their perceived reliability of EES and willingness to comply with EES. To validate the hypotheses in our research model, we designed a targeted questionnaire and collected 397 valid responses from airport terminals in four major cities in China. The results substantiate the presence of the Halo Effect and reveal the significant impact of certain dimensions of WS performance criteria on passengers’ reliability perception and their willingness to comply. The findings emphasize the mediating role of perceived reliability in converting environmental design into behavioral intentions and actions, offering theoretical insights and practical recommendations for optimizing WS design to improve routine services and emergency preparedness in airport management.

Different methods for assessing SA were logged during AD-mode and during takeover situations including subjective ratings, gaze behaviour, performance and probe measures. The impact of the manipulation of visual attention during AD mode on the different measures of SA as well as their relation to each other is analysed, reported and discussed. Results show pronounced differences between levels of attention during AD-mode in subjective SA, gaze behaviour and performance measures while preventing visual processing of the driving scenery completely while during AD mode caused surprisingly little impact. A relation between measures of SA and performance can be shown for specifically designed takeover scenarios with increased demands on SA. On the one hand, this implies that there can be a critical impact of SA on performance in takeover situations but it also highlights the robustness and efficiency of drivers’ visual processing that enables safe takeover responses even in situations with only little visual processing before a takeover.

While marijuana is well-known to impair driving, determining if its recreational use directly causes more traffic fatalities remains contentious due to challenges in roadside impairment testing. Additional challenges arise because (i) Simulations may not accurately replicate driver impairment and road conditions, (ii) Estimation based on observational data must adjust for (unobserved) confounding factors, requiring an innovative model to generate causal inference, and (iii) The dynamic, evolving nature of the process requires capturing temporal relationships. This paper contributes by employing a rigorous study design based on an augmented synthetic control method to assess the causal impact of recreational marijuana legalisation on traffic fatalities. It identifies a consistent but lagged pattern of increased fatality rates in several states post-legalisation, with the effect primarily linked to the drug’s retail availability.

These notifications inform drivers about the presence of approaching vehicles from behind in adjacent lanes, aiming to improve their performance after receiving lateral collision warnings. The improvement is measured by analyzing the differences in drivers’ reaction times and exhibition of appropriate reactions when early notifications are present and absent. Additionally, the effects of confounding factors including display formats (visual-only versus visual-auditory), drivers’ socio-demographics, and driving experience on drivers’ reaction times and exhibition of appropriate reactions are considered in the binary logit and Tobit models. Furthermore, the effects of individual heterogeneity are accounted using the random parameters approach.

The working memory is a crucial component of the cognitive function, which is closely related to the processing of short-term information. Therefore, this paper investigates the impact of the complexity of the warning messages on the behavior and physiological states of the driver, taking into account individual differences in working memory capacity and cognitive load levels. A total of 37 participants are recruited to conduct a 4 (warning information complexity) × 2 (working memory capacity) × 2 (cognitive load) mixed design driving simulation experiment, with working memory capacity treated as a between-subjects factor. An eye-tracker and a physiometer are employed to record participant’s visual motion and heart rate. A correlation analysis is then conducted to identify key dependent variables, and a Generalized Linear Mixed-effects Model (GLMM), which considers random effects, is used to analyze the impact of each experimental factor on the drivers. The obtained results demonstrate that visually rich warnings lead to increased braking reaction times, especially between drivers having low working memory capacity and under high cognitive load. Although detailed warnings are easier to understand, they tend to reduce Root Mean Square of Successive Differences (RMSSD) of the driver under higher cognitive loads, indicating increased tension and annoyance. In addition, the combination of visually simple and auditorily rich warnings has significant advantages, allowing almost all types of participants to perceive risks more quickly, which significantly reduces the collision risks.

Machine learning methods have demonstrated good performance in this field, but existing approaches often face challenges in integrating multimodal data and handling multi-task temporal predictions. To address these issues, this work proposes a novel Attention-enhanced Multimodal Temporal Network (AMTN) for predicting occupant crash response curves across multiple body regions during crashes. AMTN integrates numerical parameters and vehicle body crash pulses through a feature extraction module, organically fuses multimodal features via cross-attention mechanisms, and decodes shared features using a modified Temporal Convolutional Network (TCN) with local sliding self-attention. A dynamic adaptive loss and multiple output layers are utilized to evaluate the importance of each task, iteratively update the learning priorities, and finally achieve multi-task prediction. Experiments on the engineering-obtained data demonstrate that the crash response curves predicted by AMTN achieves an average ISO (International Organization of Standards) rating of 0.835 across 11 crash response curves, with critical regions exceeding 0.9. In engineering applications, an ISO rating greater than 0.8 indicates that the predicted curve closely matches the reference curve. Therefore, the experimental results demonstrate that the proposed method has effectively learned the characteristics of the training data and is capable of producing accurate predictions. In summary, this work advances multimodal deep learning for crash safety by enabling efficient, accurate, and interpretable multi-task curve predictions. Consequently, it can be applied to data-driven vehicle safety development, offering significant engineering value by enhancing both development efficiency and quality.</div></div>","PeriodicalId":6926,"journal":{"name":"Accident; analysis and prevention","volume":"220 ","pages":"Article 108140"},"PeriodicalIF":5.7,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144297021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the influence of this behavior on crash risk given that drivers have unexpected interactions with pedestrians and must take additional evasive actions, limited pedestrian models have accounted for jaywalking behavior. This research uses Multiagent Adversarial Inverse Reinforcement Learning (MAAIRL) within a Markov game framework to model road user behavior in jaywalking scenarios at signalized intersections, offering a detailed representation of the dynamic and complex decision-making strategies of pedestrians and drivers in these situations. This approach enables obtaining reward functions that can be used to make inferences about their behaviors and optimal policies that represent the best sequences of decisions, which can be used in developing microsimulation models. Results show that jaywalking pedestrians exhibited erratic movements, with higher acceleration rates and unpredictable paths. In contrast, non-jaywalking pedestrians showed more predictable behavior with smaller variations in their paths and greater distances from vehicles while crossing. Additionally, jaywalking scenarios led to smaller time-to-collision (TTC) and post-encroachment time (PET) values, reduced minimum distances, and faster pedestrian movements compared to non-jaywalking scenarios, which shows the increased crash risks associated with jaywalking. Finally, the MAAIRL model was able to adequately learn the behaviors associated with both non-jaywalking and jaywalking pedestrians. This shows the potential of this framework to model complex real-world scenarios. These findings underscore the importance of improving pedestrian simulation models to take into account the distinct behavioral patterns associated with jaywalking, and such advancements can facilitate a more comprehensive examination of the safety impacts in busy pedestrian environments.</div></div>","PeriodicalId":6926,"journal":{"name":"Accident; analysis and prevention","volume":"220 ","pages":"Article 108141"},"PeriodicalIF":5.7,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144280084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
