The results indicate that: when the collision speed is low, there is little difference of the child FE model's injury criteria in the two restraint systems, while the protective effect of child seat restraint system to the children is better than booster with the increase of the collision speed.","PeriodicalId":35143,"journal":{"name":"International Journal of Vehicle Safety","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49068537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Safety evaluation of highways helps engineers in prioritising them for safety improvement and for evaluating the effectiveness of the improvement measures. Crash prediction models are very useful for evaluating the safety levels of highway elements. Many studies reported the effect of geometry and traffic factors on safety at simple (single) horizontal curves. But the situation becomes more complex when multiple horizontal curves occur. The Highway Safety Manual also does not provide a safety performance function on multiple horizontal curves. Hence, this study aims to quantify the influence of geometric characteristics of the preceding curve on crashes and develop models for evaluation of the safety performance of multiple horizontal curves on two-lane non-urban roads. The data required for this study include crash, geometric, and traffic data from 102 multiple horizontal curves.","PeriodicalId":35143,"journal":{"name":"International Journal of Vehicle Safety","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43856634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results of rear-seat sled tests with an obese (BMI = 35) Post Mortem Human Surrogate (PMHS) were used to evaluate the performance of the obese HBM in matching conditions. Also, the responses of a non-obese HBM (BMI = 25) and the obese HBM were compared in a front-seat frontal impact test. In the rear-seat tests, both the obese HBM and the obese PMHS experienced a large forward excursion, delayed lap belt engagement with the pelvis, and a reclined-to-upright torso angle throughout the tests, which were the effects of large body mass and thick flesh. In the front-seat simulations, the obese HBM experienced a larger excursion than the non-obese HBM. The obese HBM can be a useful tool to design and optimise restraint system for front-seat occupants with obesity.","PeriodicalId":35143,"journal":{"name":"International Journal of Vehicle Safety","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49208250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The elderly pelvis model was compared with the young people's pelvis model and the children's pelvis model. The results show that the physiological and geometric size of pelvic model of elderly is similar to that of young people, but both of them are quite different from the children's. Compared with the other two models, the elderly pelvic model has the strongest response of peak force and Dforce (deflection at maximum force), but the weakest response of maximum deflection under different impact velocities from 4 m/s to 15 m/s. The peak force and Dmax increased exponentially and linearly with the impact energy in all three models, respectively. The most vulnerable parts of the injury were the ischio-pubic rami, iliac-sacral junction and acetabulum area.","PeriodicalId":35143,"journal":{"name":"International Journal of Vehicle Safety","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44537419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
