We conducted a retrospective cohort study using Taiwan’s Police-Reported Traffic Accident Registry (2019–2021), Taiwan Death Registry, and Taiwan National Health Insurance database (2016–2021). Two cohorts were established: a population-based sample of older motorized two-wheeler riders involved in crashes and a hospital-based sample of those admitted on the same day or one day after MVCs. The primary outcome was 30-day all-cause mortality. Predictive variables included injury severity, demographics, comorbidities, behaviors, and environmental factors. Logistic regression models assessed predictors, with model performance evaluated using the area under the receiver operating characteristic curve (AUC). Significant predictors of 30-day mortality included severe injury, head and neck trauma, older age, alcohol consumption, unlicensed riding, and crash location. Diabetes mellitus was a significant predictor in the population-based sample but not in the hospital-based sample, highlighting differences in data capture. Both models showed acceptable predictive ability, with AUC values of 0.80 and 0.84, respectively.

However, current studies predominantly analyze crash data based on oversimplified classification schemes that lack clear scenario definitions. Consequently, they impede an in-depth investigation of crash characteristics. Pre-crash scenario typology classifies crashes based on vehicle dynamics and kinematics features. Building on this, characteristics analysis can identify similar features under comparable crashes, offering a more effective reflection of general crash patterns and providing more targeted recommendations for enhancing AV performance. In this paper, we initially collected the latest 774 California AV crash reports, then selected 384 autonomous mode crashes, and used the newly revised pre-crash scenario typology to identify AV pre-crash scenarios. To improve the efficiency of scenario identification and adaptability to future updates in scenario typology, we proposed a set of mapping rules to extract pre-crash scenarios automatically. We successfully identified 27 types of AV pre-crash scenarios with an accuracy of 98.1%. Through detailed analysis, we obtained two key groups of AV pre-crash scenarios: rear-end scenarios and intersection scenarios. Based on the abundance of crash data, we adopted different analysis methods to analyze the features of key scenarios. Association analysis of rear-end scenarios showed that the significant environmental influencing factors were traffic control type, location type, light, etc. For intersection scenarios prone to severe crashes with detailed descriptions, we employed causal analysis to obtain the significant causal factors: habitual violations and temporary obstruction of view. The extracted scenarios in this paper and their features can assist in constructing the AV simulation test with precise environmental parameters and realistic interactions with other traffic parties. The resulting optimization recommendations can inform regulators and reveal control-algorithm weaknesses across diverse real-world conditions, thereby enhancing the AV safety.</div></div>","PeriodicalId":6926,"journal":{"name":"Accident; analysis and prevention","volume":"224 ","pages":"Article 108285"},"PeriodicalIF":6.2,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145414254","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}

Estimating the effect of speeding on crashes is, however, very challenging due to several reasons. Traditional speeding data collection methods often introduce measurement error in the analysis. In addition, there is a complex inter-relationship between driver behaviour, roadway geometry, and crash risk leading to endogeneity between speeding and crash risk. While instrumental variable modelling has been previously used for addressing such endogeneity, the effectiveness of this technique depends on strong instruments that correlate well with speeding but not with crashes.

The negative binomial model is specified with random parameters and mixed spline indicators accounting for unobserved heterogeneity and temporal instability in the data. Results indicate high predictive power of the machine learning model in predicting speeding from exogenous variables, complemented by intuitive shapley values and feature importance for those variables. A comparison of statistical fit between the proposed model and several state-of-the-art modelling candidates showed that our model is superior to the existing modelling techniques.

Prior research has predominantly utilized the “5D” framework to examine how the built environment influences accident rates. However, intersections, which are high-risk areas for traffic accidents, are significantly influenced by their surrounding streetscape features. These features have not been systematically integrated into the existing “5D” framework of the built environment. Moreover, previous studies considered intersections as isolated units, employing analytical models that presuppose sample independence and neglect the spatial spillover effects of explanatory variables due to the interconnected nature of these units. To overcome these limitations, this study introduces a sixth dimension to the built environment, the Detailing of Intersection Interface, by incorporating surrounding streetscape features at intersections. This dimension is quantified using semantic segmentation techniques to calculate the pixel proportions of static streetscape elements from Street View Images (SVIs). Furthermore, to capture the spatial spillover effects of built environment characteristics at neighboring intersections, a spatial topology graph was constructed, defining intersections as nodes and road connections as edges. A Graph Attention Network (GAT) model was subsequently developed to predict accident occurrences at intersections, effectively accounting for the spatial dependencies of accident risks. A dual-model interpretability framework, combining eXtreme Gradient Boosting-Shapley Additive exPlanations (XGBoost-SHAP) and GAT-GNNExplainer, was established to explore the association between built environment characteristics and accident occurrence from global, neighborhood, and individual perspectives. The results demonstrate that the two-layer GAT model (GAT-2) achieved an accuracy of 80.05%, marking a significant improvement in predictive performance by accounting for the spatial spillover effects of built environment features at nearby intersections. From the global perspective, critical factors influencing intersection traffic accidents include POI density, building density, traffic facility density, and distance to bus. These factors exhibit significant nonlinear and threshold effects, as well as strong interaction effects among them. From the neighborhood perspective, intersection traffic accidents are influenced by local built environment features but also by those of adjacent intersections, and the GAT-GNNExplainer framework effectively identified the key neighboring intersections and their key features contributing to accident occurrence, thereby effectively quantifying the spatial spillover effects of built environment features.

Despite considerable progress, real-world usage and testing of AVs continue to highlight vulnerabilities, particularly in safety-critical situations. This study examines how vehicle failure, the type of failure (security vs. mechanical), and the scenario context influence drivers’ trust and risk perception toward AVs. Initially, six categories of failure scenarios were identified using data from the California Department of Motor Vehicles’ disengagement reports. Subsequently, an online experiment was conducted, where participants experienced both baseline (normal operation) and failure drives. In the failure drive, participants encountered one specific failure type and scenario. The results revealed a substantial decrease in driver trust following the failure drive across all conditions. Higher perceived risk was associated with reduced trust and lower risk-taking behaviors. Scenarios were classified into high- and low-risk categories, with control-related issues having the most pronounced effect on increasing perceived risk. The experiment found no difference in trust or risk perception whether the failure was caused by a malicious intervention or a mechanical issue. These findings suggest that AV design should incorporate mechanisms for assessing and appropriately responding to varying risk levels in critical situations.
