As such, the present study aimed to explore two research questions: 1) what type of technology is used and how is it used, and 2) how does drivers’ use of this technology influence deterrence for road rule violations. In total, 58 Queensland licenced drivers who use technology that informs them of legal enforcement while driving participated in focus groups. To consider differences in use between ages, the sessions were conducted in three different age groups: 17–25 years, 26–49 years, and 50+ years. Reflexive thematic analysis was applied to the data, resulting in eight recognised themes. The findings highlighted that for most drivers, the primary purpose of using the technology was for navigation, while being notified of enforcement locations was a secondary purpose. In addition, the use of this technology encouraged road rule compliance for some yet was used as a strategy to avoid being caught for road rule violations for others. The findings have a number of practical and theoretical implications, demonstrating the complex interplay between technology used for enforcement notifications, its role in deterring road rule violations, and the principles of responsible innovation.</div></div>","PeriodicalId":21375,"journal":{"name":"Safety Science","volume":null,"pages":null},"PeriodicalIF":4.7,"publicationDate":"2024-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142561027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, the safety of storing SRM is a critical concern. In this paper, the Computational Fluid Dynamics (CFD) numerical simulation method is applied. The structure and flow parameters of the flow field are obtained using the Naiver-Stokes (N-S) control equations, the Realizable k-epsilon turbulence model, and the finite rate model. We investigate the hazardous properties of a standard storage compartment equipped with an exhaust cover and spray system in the event of an accidental jet fire. Furthermore, the safety parameters of the storage compartment are examined. The results showed that the jet flame was initially directed at the side walls, spread to the upper part, and propagated throughout the storage compartment. Using the response times and thresholds of the temperature and pressure sensors, the study determined the optimal activation time for the pressure relief port and water spray system to be 0.4 s and 0.1 s, corresponding to a spray intensity of 0.5 kg/s. The synergistic effects of the pressure relief exhaust cover and spray mechanisms could quickly reduce the temperature of the compartment below the critical threshold of 500 K, thereby preventing thermal hazards associated with propellant combustion within 10 s. The optimal location and time of entry into the storage compartment are determined based on monitoring the mass fraction of gases in the compartment while maintaining temperature and pressure safety limits. The results will provide theoretical foundations for improving secure memory design practices on SRM.</div></div>","PeriodicalId":21375,"journal":{"name":"Safety Science","volume":null,"pages":null},"PeriodicalIF":4.7,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142537579","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}

Analysis of performance resulted in the removal of another nine clips, resulting in a final VR-PSCT comprising 13 hazard perception and 11 gap acceptance clips. Adults responded more often within the designated hazard and gap windows, had significantly faster response times, and accurately identified hazards more often than children.

Using slip resistant winter footwear is a key factor in reducing the risk of slips and eventually falls. In this study, we developed an Artificial Intelligence model that classifies high and low slip resistant footwear based on images of their outsoles. Our model was trained on a unique dataset which consisted of images of 266 winter footwear outsoles. This dataset included footwear outsoles made from rubber (n = 89), Arctic Grip (n = 101), and Green Diamond material (n = 76). The slip resistance of all footwear samples was tested and rated with a human-centered protocol called the Maximum Achievable Angle test. We applied a transfer learning technique to develop a 2D convolutional neural network to classify the outsoles as having high and low slip resistance. The best classification model used the Xception pre-trained model and obtained an accuracy and F1-score of 0.85 and 0.89, respectively. The AUC-ROC (Area Under the Curve for Receiver Operating Characteristic) was also 0.91. Our results suggest that the proposed model properly identified high and low slip resistant winter footwear outsoles. Our findings also confirmed that the footwear’s outsole tread pattern and material directly impact the footwear’s slip resistance quality. The proposed model will help footwear manufacturers to improve their workflow and increase product quality which can ultimately decrease the events of slips and falls.</div></div>","PeriodicalId":21375,"journal":{"name":"Safety Science","volume":null,"pages":null},"PeriodicalIF":4.7,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142529256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
