The city of Oslo was not affected by the reforms in 2020 and 2024. The other counties were affected either by: (1) Transfer of the management of county roads only (one county); (2) transfer of the management of county roads and merger with another county (one county); or (3) transfer of the management of county roads and merger with another county, followed by splitting up the merged counties (two counties). A before-and-after study with comparison group using county roads as treated group and other public roads as comparison group, and 2010–2019 as before-period and 2020–2023 as after-period found very small changes in the number of injured road users.

This problem is especially prominent in dynamic traffic scenarios. Therefore, this paper proposes a safe self-evolution algorithm for autonomous driving based on data-driven risk quantification model. Specifically, a risk quantification model based on the attention mechanism is proposed by modeling the way humans perceive risks during driving, with the idea of achieving safety situation estimation of the surrounding environment through a data-driven approach. To prevent the impact of over-conservative safety guarding policies on the self-evolution capability of the algorithm, a safety-evolutionary decision-control integration algorithm with adjustable safety limits is proposed, and the proposed risk quantization model is integrated into it. Simulation and real-vehicle experiments results illustrate the effectiveness of the proposed method.

Addressing this issue effectively requires sophisticated analytical methodologies to elucidate and mitigate the multifaceted factors contributing to traffic fatalities. This study introduces the Negative Binomial Generalized Seasonal Autoregressive Integrated Moving Average with Exogenous Variables (GSARIMAX) model as an innovative approach for analyzing low temporal (daily) and large spatial count data of fatal crashes over a ten-year period (March 2014 to March 2022) in Iran. Unlike traditional models that predominantly focus on aggregated monthly or high-resolution data, the proposed negative binomial GSARIMAX model leverages daily count data, accommodating over-dispersion inherent in crash counts and providing a more granular and accurate analysis across extensive spatial regions. The model integrates significant exogenous variables, including traffic volume, maximum and minimum temperatures, wind speed, and wind direction, alongside harmonic seasonal components to capture both annual and semi-annual periodic fluctuations in crash occurrences. Model performance was rigorously evaluated using Deviance Information Criterion (DIC) and Mean Absolute Relative Error (MARE) metrics, alongside out-of-sample predictive accuracy assessments. The negative binomial GSARIMAX (0,1,2)-SOH model demonstrated superior performance compared to the Gaussian GSARIMAX counterpart, evidenced by lower MARE and DIC values. Notably, traffic volume and maximum temperature emerged as significant predictors of fatal crashes, while seasonal harmonic terms further enhanced model accuracy by effectively capturing temporal dynamics. The Bayesian estimation framework employed facilitates robust inference and the analysis of posterior predictive distributions, affirming the Negative Binomial GSARIMAX model’s superior fit and forecasting capabilities. These findings underscore the model’s potential advantages over conventional Gaussian statistical methods, particularly in handling low temporal resolution and large spatial datasets. Moreover, dynamic models incorporating exogenous variables demonstrated enhanced predictive performance, highlighting the importance of integrating diverse factors in crash analysis. This study not only advances the methodological landscape for traffic crash analysis but also provides actionable insights for policymakers and safety authorities. By identifying key determinants of fatal crashes and accounting for seasonal variations, the Negative Binomial GSARIMAX model serves as a valuable tool for informing targeted interventions aimed at reducing traffic fatalities.

By employing simulated virtual reality (VR) experiments, this study investigated how the environment of an unsignalized T-junction in a school zone influenced the perceived safety, crossing behaviors, and visual attention of 178 participants, consisting of younger (aged 8–10) and older children (aged 11–12) and their parents. Key findings from cross-classified multilevel, trajectory, and counterfactual analyses using Reproduced Virtual Experiment Data (CARVED) techniques for viewed scene comparisons are as follows. First, despite their physical and cognitive limitations, children—particularly younger ones—exhibited fewer attentive behaviors on sidewalks and roadways, along with a higher informal crossing ratio than parents. Second, responses to environmental conditions varied by developmental stage. While older children and parents generally responded to hazardous conditions with increased caution, younger children exhibited minimal behavioral adjustments. For example, parents perceived environments with parked cars as less safe and demonstrated more attentive and preventive behaviors on roadways. In contrast, younger children, despite having their line of sight obstructed, failed to recognize these hazards and did not adopt compensatory strategies, reinforcing their vulnerability. Similarly, only older children and parents perceived decorative crosswalk patterns as less safe than traditional ones. Third, while traditional crosswalks facilitated orthogonal crossings and provided clearer guidance for safer movements, decorative patterns often encouraged diagonal and dispersed crossings, resulting in a higher jaywalking ratio. Lastly, speed limits showed no significant influence on perceived safety or crossing behaviors. These findings highlight the critical influence of developmental stages on safety perceptions and behaviors, emphasizing the need to reassess crosswalk designs and address visibility challenges caused by illegal on-street parking to enhance child pedestrian safety.</div></div>","PeriodicalId":6926,"journal":{"name":"Accident; analysis and prevention","volume":"213 ","pages":"Article 107959"},"PeriodicalIF":5.7,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143395349","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}

The use of driving simulators is still on the rise, with the increased number of low-cost desktop-based driving simulations, primarily motivated by research in the intersection of vehicle automation and human factors. However, it is necessary to ensure that the simulators correctly represent the driving task, which is done through the validation process and has been particularly rare in recent years. In this sense, the objective of the present work is to support the validation efforts of low-cost driving simulators in two ways: (i) by proposing a study configuration categorization to guide validation studies and (ii) by presenting the validation of an immersive driving simulation based on the proposed classification. Considering the former, an extensive literature review of existing validation studies was conducted to support this classification’s development. Regarding the latter, data from the same scenario in the real world and in the virtual environment were collected and analyzed. The study also evaluated the occurrence of simulator sickness and the perception of realism in the simulated scenario, which are important elements in the context of low-cost driving simulators. The results show relative validation for the particular simulator analyzed, as well as the relevance of virtual reality for constructing an immersive environment, despite a slight increase in some symptoms of simulator sickness.

To address this issue and reduce both carbon emissions and fuel consumption, the road transportation system is undergoing a significant transformation with the development of autonomous truck platoons (ATPs). Despite the promising potential for large-scale deployment of ATPs and the substantial number of human-driven heavy-duty trucks currently in operation, research on the lateral interactions between truck platoons—whether human-driven or automated—and surrounding passenger cars remains limited. Given the absence of commercially deployed ATPs, this study proposes extracting truck platoons from real-world trajectory datasets to investigate the interactions between truck platoons and surrounding vehicles. A two-dimensional surrogate safety measure (SSM) known as Anticipated Collision Time (ACT) was employed to characterize these interactions. Bayesian Survival Analysis was developed to examine the interactions between truck platoons and adjacent passenger cars to provide some insights into how truck platoon might impact surrounding traffic. The results reveal that the position of the adjacent or right-leading truck in the platoon greatly influence the hazard of a minimum collision time. The increase of average time headway between trucks in platoon is found to shorten human drivers’ responsiveness time to truck platoons. Moreover, the presence of a leading vehicle causes human drivers to reach the minimum collision time with truck platoons earlier, and this impact strengthens as the passenger car overtakes the truck platoon. These findings help us better understand the lateral interactions between truck platoon and adjacent passenger car, offering a theoretical foundation for traffic simulation involving heavy-duty truck platoons and recommendations for safety management of traffic flow involving truck platoons for future highways.</div></div>","PeriodicalId":6926,"journal":{"name":"Accident; analysis and prevention","volume":"213 ","pages":"Article 107945"},"PeriodicalIF":5.7,"publicationDate":"2025-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143372229","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}

To address these methodological limitations, this study develops a geographically weighted atrous convolutional neural network regression model (GACNNWR) to more accurately capture the spatial heterogeneity in the impact of built environment factors on traffic safety. Based on empirical data of traffic accidents and built environment from Jinan City, our results demonstrate that the GACNNWR model outperforms traditional analytical methods such as GWR model. Intersection density and bus stop density are identified as having a more substantial impact on traffic accidents compared to population density, land use mix, and destination accessibility. Additionally, population density is shown to exert a bidirectional influence on traffic accidents, while the spatial variability in the effects of land use mix is relatively pronounced.

Nevertheless, due to the system’s characteristics, particularly regarding right-of-way issues, crashes involving trams often lead to severe consequences. This study utilizes traffic crash data from across Japan, including 1,121,299 crashes that occurred from 2019 to 2022, of which 304 were tram involved. The study has two major analyses using random-parameter model with heterogeneity in means: (1) tram-involved crashes’ characteristics (vs. non-tram-involved) and (2) factors affecting the probability of fatality in tram crashes. The first analysis’ findings suggest that fatalities and crashes at rail crossings are more likely to be associated with tram crashes, while non-tram crashes are more likely to occur during daytime, at intersections, or on narrower lanes. Furthermore, the presence of a median between opposing directions increases the likelihood of a non-tram crash. The second analysis to identify the factors influencing fatality reveals how factors such as the season, lighting conditions, road conditions, crash locations, and the age and category of victims affect the characteristics of tram crashes and fatalities. Specifically, it explains the heterogeneous effects of daytime and intersections on tram crashes, as well as the heterogeneous impacts of rail crossings and densely populated areas on tram fatalities. The findings are expected to assist authorities in formulating strategies to minimize the incidence of tram crashes and related fatalities, potentially saving lives and bringing about economic benefits.</div></div>","PeriodicalId":6926,"journal":{"name":"Accident; analysis and prevention","volume":"213 ","pages":"Article 107919"},"PeriodicalIF":5.7,"publicationDate":"2025-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143350286","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}
