This study looks at perceptions of safety and danger regarding crime in Medellín, Colombia. I used two different datasets to look at this issue in both the specific situations that incite fear of crime and in the broader context of perceived safety and danger across the city as a whole. The first dataset comes from 42 interviews that I conducted with university students in May of 2009. The inte...

This letter introduces integral control barrier functions (I-CBFs) as a means to enable the safety-critical of nonlinear systems. Importantly, I-CBFs allow for holistic encoding both state constraints and input bounds in single framework. We demonstrate this by applying them dynamically defined tracking controller, thereby enforcing safety through minimally invasive I-CBF controller framed quad...

The predominant risk culture within the UK surrounding protecting children from online predators has a strong influence on the type of awareness raising activities being promoted for children. As reflected in the terminology in the field, e-safety has moved through Internet Safety to be commonly referred to in child protection circles as online safeguarding. Whether this change in terminology b...

Advanced driver support systems are often used by drivers as comfort systems. Drivers tend to adapt their behavior to the increased safety margins created by the system by driving at higher speeds and paying less attention to driving. From a traffic safety perspective, it is therefore important that driver support systems can adapt their support to how drivers actually use the system. We propos...

This study aimed to investigate the relative performance of two models (negative binomial (NB) model and two-component finite mixture of negative binomial models (FMNB-2)) in terms of developing crash modification factors (CMFs). Crash data on rural multilane divided highways in California and Texas were modeled with the two models, and crash modification functions (CMFunctions) were derived. T...

objectives: the objective of this study is to evaluate the safety climate as an important part of macroergonomics domains and to determine the importance of each safety climate factor in an iranian company. methods: for data gathering, the researchers used macroergonomic organizational questionnaire survey (moqs) method. for conducting this method we applied safety climate questionnaire which h...
