Over the past two decades, highways in suburban areas of many Chinese cities, originally designed for medium- and long-distance vehicle travel, now accommodate more short- and medium-distance trips, including pedestrians and cyclists. Discrepancies between original planning characteristics and current usage have led to increased safety risks at suburban arterial intersections. This study evaluates the effectiveness of safety countermeasures implemented at 32 intersections across six suburban arterials in Suzhou, China, which were improved in 2021. To address unobserved heterogeneity and selection bias, a propensity score matching-full Bayes (PSM-FB) method was employed to calculate crash modification factors (CMFs) by balancing the distribution of variables between treatment and control groups. The random effects negative binomial (RE-NB) model was used as the safety performance function (SPF) to account for unobserved heterogeneity among arterials and intersections. Three safety countermeasures were analyzed: physical separation of bicycle lanes, installation of mandatory stop signs for large vehicles at right turns, and removal of obstructions to improve sight distances. Results indicate significant reductions in crashes across all types and severities, with CMFs below 1.0 for all countermeasures. Physical separation of bicycle lanes demonstrated notable effectiveness in reducing bicycle- and pedestrian-related crashes. The PSM-FB method effectively addressed unobserved heterogeneity and selection bias, offering a robust framework for safety evaluation. This study contributes to improving suburban arterial intersection safety and provides methodological insights for future evaluations.</div></div>","PeriodicalId":6926,"journal":{"name":"Accident; analysis and prevention","volume":"221 ","pages":"Article 108217"},"PeriodicalIF":6.2,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144902231","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 mitigate this problem, it is essential to understand factors influencing parents’ safe riding behaviors when transporting their children. By integrating the Health Belief Model (HBM) and the Theory of Planned Behavior (TPB), this research aims to provide valuable insights into the key elements that shape parents’ riding behaviors. Data were collected using a face-to-face survey design involving 444 parent motorcyclists in Danang City, Vietnam. Structural equation modeling analysis revealed that perceived susceptibility, perceived severity, and perceived benefits from the HBM model, as well as attitude and perceived behavioral control from the TPB model, directly influence parents’ intentions to engage in safe riding behaviors. The impact of knowledge about traffic laws on safe riding behaviors intention is also confirmed. In addition, control variables such as age, frequency of carrying children and experience accidents with children also play a role in shaping these intentions. The results of the moderation analysis indicate that perceived severity has a stronger influence on safe riding intentions among parents with low child passenger safety knowledge, whereas this effect is weaker for those with high knowledge. The analysis also reveals that subjective norms positively affect parents with low knowledge but have a negative impact on those with higher levels of knowledge. The findings of this study offer valuable insights for policymakers and relevant authorities to develop policies aimed at reducing unsafe riding behaviors among parents.

Moreover, there is a need to account for the different effects of physical measures (speed humps, cameras) and sign-only measures, when examining the benefits of 20mph limits.

Furthermore, the introduction of 20mph speed limits with physical measures resulted in greater reductions in crashes and casualties than sign-only schemes.

However, practical approaches for crash risk management and safety evaluation have not been fully developed to capitalize on this high-value driving data.

First, univariate extreme value models were developed to determine the thresholds of crash risk for two kinematic indicators under different loading conditions. Then, various bivariate logistic-based extreme value models were developed to analyze the dependence structure between the two kinematic indicators, construct probability-based crash risks, and estimate them according to the thresholds. The univariate and bivariate block maxima models were applied to the dataset containing 3,452 trips from 64 heavy vehicles recorded in Hangzhou, China. The results show that the Speed time-varying stochastic volatility (Speed-<span><math><msub><mi>V</mi><mi>f</mi></msub></math></span>) and Jerk are effective indicators for assessing the driving risks of heavy vehicles.

Recent advancements in connected vehicle (CV) technologies, particularly cellular vehicle-to-everything (C-V2X), are expected to enhance driver decision-making by providing real-time traffic information. Despite this, most previous studies have not considered the latest C-V2X specifications, leaving critical questions unanswered about how drivers interact with and benefit from this technology in dilemma-zone scenarios. To address this gap, this study builds a co-simulation platform that integrates Unity and VISSIM to simulate four communication conditions: (1) no communication (baseline), (2) perfect communication (green-light countdown), (3) interrupted communication (green-light countdown with loading delays), and (4) communication loss due to the absence of smart infrastructure (out of service information). Sixty-two licensed drivers participated in four randomized trials, each with multiple unpredictable green-to-yellow transitions designed to capture dilemma-zone responses. Driving performance was assessed in terms of stop-or-go decisions and red-light running outcomes. Results of the random parameters binary logit model for stop-or-go decisions indicate that, compared to no communication, drivers are more inclined to proceed through the intersection when communication is lost. In contrast, perfect communication and communication interruption generally reduce this tendency. Furthermore, significant interaction effects revealed the observed heterogeneity, indicating that drivers with specific driving histories respond differently under communication interruption and loss conditions. For the red-light running outcomes, the descriptive analysis shows that under the perfect communication condition, the proportion of red-light running decreases by 3.44% among drivers. Interestingly, even interrupted communication leads to a 2.19% decrease in the proportion of red-light running outcomes. These findings demonstrate the complex ways in which C-V2X-based information can influence driver decisions, emphasizing the need for robust implementation strategies that are context-aware. This study sheds light on how drivers interact with emerging C-V2X systems and provides insights for road authorities and policymakers seeking to enhance safety and reduce crash risks at signalized intersections.</div></div>","PeriodicalId":6926,"journal":{"name":"Accident; analysis and prevention","volume":"221 ","pages":"Article 108208"},"PeriodicalIF":6.2,"publicationDate":"2025-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144879518","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}

A personalized perspective on driving risk assessment and prediction can help to proactively prevent traffic safety and provide a risk prediction basis for intelligent driver assistance systems. A personalized driving risk assessment and rolling prediction method is proposed to predict a driver’s potential accident risk in real-time by integrating vehicle dynamics and Heart Rate Variability (HRV) indicators. A natural driving experiment is designed to obtain Critical Incident Events (CIEs) and changes in each indicator. The frequency of CIEs is used as a driving risk characterization. To identify the significant personalized indicators affecting various CIEs, an improved Bayesian network model is developed to obtain the influence mechanism of each indicator on CIEs. The Dynamic Time Warping Barycenter Averaging (DBA) method is used to calculate the representative series of each significant indicator, which can obtain the characteristic time series under different risk levels. The weights of each CIE class are calculated by the entropy weight Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) to get the risk score calculation rule. These scores are then clustered by the Fuzzy C-means (FCM) algorithm to determine the different risk levels. Finally, the Bayesian Optimization (BO) −based Bidirectional Gated Recurrent Unit (BiGRU) is integrated with a Convolutional Neural Network (CNN) and Extended Kalman Filter (EKF) to construct the BCBGE (BO-CNN-BiGRU-EKF) model, which enables continuous prediction of driving risk. Results from a natural driving experiment involving 60 drivers in Xi’an indicate that driving risk can be grouped into four levels. A personalized risk indicator analysis was conducted for each driver. The results indicate that each type of CIE is associated with three to four key indicators of vehicle dynamics or HRV.

Qualitatively, typical phenomena of the interaction between the visually and hearing-impaired individuals, and spatial features around the wheelchair users can be observed through the video recordings. Qualitatively, the path length ratio (PLR) and entropy of trajectories for different disabled are calculated and compared. With regard to the typical phenomenon, the Cross-Correlation Function (CCF) was quantified to measures the similarity between the interaction, including “shoulder guide” cooperative movement of the visual disabled and interacting with each other of the hearing disabled.

It is demonstrated that the traffic efficiency of the heterogeneous group is lower than that of the elderly group and the building code standards. Various parameters such as passage time, actual speed, effective speed, instantaneous speed, stagnation time, and acceleration are calculated to analyze the impact of disability types on pedestrian passage efficiency. Factors contributing to the reduced traffic efficiency of the heterogeneous group are analyzed from temporal and spatial perspectives. Wheelchair users experience more pronounced stoppages due to their larger space requirements. Additionally, the reaction time and the collision avoidance behaviors of pedestrians in the heterogeneous group lead to longer exit intervals. This results in a relatively dispersed concentration of crowd density within the experimental space. These findings underscore the importance of enhancing crowd management and optimizing traffic designs for heterogeneous groups with various types of disabilities for ensuring their mobility and safety.
