Previous research on wrong-way driving (WWD) has emphasized the frequent incidents at the off-ramp terminals of parclo interchanges. Many WWD incidents that did not result in a collision haven't received enough attention from researchers. Geometric features such as ramp design, signage placement, and interchange layout significantly influence driver behavior and decision-making. In this study, a comparative analysis was conducted to explore the correlation between geometric design elements and their impact on WWD incidents at parclo interchange terminals. Over 5000 h of video footage were meticulously reviewed to document instances of WWD at 75 parclo interchange terminals across 13 states. Multiple correspondence analysis was applied to explore the characteristics of the locations with recurring WWD incidents. The results revealed numerous associations among design elements that contributed to the increased risk of WWD incidents, including uncontrolled ramp terminal intersections without street lighting on a two-lane crossroad, poor pavement marking on a wide median between the on- and off-ramps, and so on. The outcomes of this study can be helpful in identifying and improving the critical geometric design criteria in parclo interchanges to minimize WWD incidents.</div></div>","PeriodicalId":47059,"journal":{"name":"IATSS Research","volume":"48 4","pages":"Pages 550-559"},"PeriodicalIF":3.2,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142663620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While most studies on the acceptance of automated vehicles have been conducted in upper-middle-income or high-income developed countries, similar research in middle-income countries is limited. This study aims to evaluate a priori acceptance of FAVs in a middle-income developing country by extending the Technology Acceptance Model (TAM).

This study aims to evaluate a priori acceptance of FAVs in a middle-income developing country by extending the Technology Acceptance Model (TAM). Trust, subjective norms, perceived safety risk and four decision-making styles (Thoroughness, Hesitancy, Social resistance, and Perfectionism) were included in the extended model. Structural Equation Modeling was applied to confirm model validation by using data from 1026 drivers from different cities in Iran. A multi-group analysis was conducted to assess whether the relationships between model constructs vary across different demographic and background groups. Additionally, an importance-performance analysis was performed to gain a deeper understanding of the factors influencing behavioral intention. The findings of the model highlighted that beyond the original TAM scales, subjective norms were the strongest predictor in explaining drivers' intentions to use FAVs. Initial trust also moderately contributed to explaining user acceptance of FAVs. The results also revealed that among decision-making styles, thoroughness positively affected behavioral intention through trust, while social resistance had an indirect negative effect on intention. The findings showed that effect of the perceived safety risk on behavioral intention through the initial trust was confirmed; however, importance-performance map analysis revealed that a significant improvement was observed in the safety area that could still be obtained. It is suggested that policymakers start promoting the usefulness and ease of use of FAVs through advertisements, social media, public campaigns and autonomous vehicle test ride events to facilitate the adoption of FAVs when available in countries with similar sociocultural contexts.</div></div>","PeriodicalId":47059,"journal":{"name":"IATSS Research","volume":"48 4","pages":"Pages 537-549"},"PeriodicalIF":3.2,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142663621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Centered on a critical junction near Sichon Municipality, the study evaluates three proposed redesign scenarios using the VISSIM simulation tool and the Safety Surrogate Assessment Model (SSAM). These scenarios include the implementation of a roundabout with guidance feature (Model 2), the introduction of a dumbbell-shaped roundabout (Model 3), and the construction of a roundabout without turning points (Model 4). Findings suggest that Models 2 and 4, which incorporate roundabouts, can reduce conflict points, potentially decreasing traffic collisions. However, these models also indicate possible increases in travel times and queue lengths, highlighting the trade-offs between enhancing safety and maintaining traffic efficiency. An in-depth analysis of Deltas (ΔS) values through Optimized Hot Spot Analysis reveals areas with high and low collision severity, providing direction for targeted safety measures. The study demonstrates the complex effects of intersection redesigns on safety and traffic flow. For instance, Model 3 shows increased conflict points, emphasizing the need for specific design considerations to counteract potential negative impacts. Conversely, Model 4 achieves streamlined traffic flow but necessitates careful design to prevent new safety risks. This research underscores the need for a comprehensive approach to intersection safety that combines infrastructure improvements with insights into driver behavior.

Many countries have adopted increasingly stringent policies in curbing DUI. Nevertheless, more and more studies show that while the total number of DUIs has reduced as a whole, DUI recidivism remains challenging. As such, this study seeks to research into whether it is possible to identify frequent DUI recidivists based on their traffic offense history, so that effective countermeasure could be put in place and in time. This study proposes using the drivers' traffic offense history and length of duration between two DUIs, the duration of re-offending, to identify frequent DUI recidivists. This approach is not only widely adopted in public health, but is also flexible in accommodating many modeling issues such as data censoring, recurrent events, and the inclusion of time-varying covariates to address questions like whether the probability of recidivism increases or decreases with subsequent DUI offenses or other traffic offenses or violations. Our major results show that: (1) For all drivers caught for a DUI, 10 % of them would be caught for another DUI within a year; (2) In contrast, the same one-year recidivism probability for those who accumulated two DUIs and two run-the-red-light could be as high as 17 %; (3) Each subsequent DUI increased the probability of a further DUI offense by 57 %; and (4) Each additional DUI offense was associated with 45 % increase in probability of being involved in a crash involving DUI. Overall, there are clear links between a driver's history of traffic offenses, DUI recidivism, and crash involvement, which could provide valuable information for authorities to profile potential recidivists and apply preventative measures in advance to reduce DUI-related crashes.</div></div>","PeriodicalId":47059,"journal":{"name":"IATSS Research","volume":"48 4","pages":"Pages 487-495"},"PeriodicalIF":3.2,"publicationDate":"2024-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142530814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This underscores the need for more in-depth investigation and empirical evidence to better elucidate the nature of the relationship between self-perceived driving skills and attitudes in the context of traffic safety. This study investigates the relationship between drivers' skills and their attitudes toward traffic safety. Data from 664 drivers were collected through self-report questionnaires covering driving skills, attitudes, and demographic information. Factor analysis revealed three distinct factors for both driving skills (perceptual-motor skills, safety skills, and decisional skills) and driving attitudes (attitudes toward rule violations and speeding, attitudes toward careless driving of others, and attitudes toward drinking and driving). Structural equation models unveiled a significant connection between drivers' attitudes and safety skills, as well as decisional skills. Improved safety skills correlated with less favorable attitudes toward rule violations, speeding, careless driving of others, and drinking and driving. Similarly, enhanced decisional skills were associated with a rise in attitudes toward rule violations, speeding, and disregarding careless driving of others. Demographic analysis indicated an inverse correlation between age and attitude factors/decisional skills, coupled with a positive correlation with safety skills. Older individuals had less favorable attitudes toward rule violation, speeding, careless driving of others, the combination of drinking and driving, and their decisional skills were lower. Gender analysis revealed that men had a lower favorable viewpoint toward all three attitude dimensions and reported higher perceptual-motor and decisional skills compared to safety skills. The findings underscore the significance of safety and decisional skills in shaping attitudes toward traffic safety. Demographic factors, particularly age and gender, play a role in influencing these skills and attitudes, offering valuable insights for interventions and policy considerations.</div></div>","PeriodicalId":47059,"journal":{"name":"IATSS Research","volume":"48 4","pages":"Pages 496-505"},"PeriodicalIF":3.2,"publicationDate":"2024-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142530815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
