Comparing Young and Old Adults’ Night Hazard Detection With Driving Simulation and on Road

While there is validity of using driving simulation as a proxy for on-road performance, few studies have examined hazard detection at night. Night driving is a self-restricting practice with little evidence demonstrating the need with healthy older adults. This study’s objective was to analyze night driving using eye-tracking technology examining differences between on-road/simulated drives and older/younger adults. A 2 (old, young) x 2 (simulator, on-road) repeated-measures design measured three roadway “hazards” of pedestrains looking at their cell phone while posed to cross the roadway. Pupil glances were recorded using outcome measures of total fixation duration, number of fixations, and time-to-first fixation for the pedestrains on-road and on a specifically designed scenario matching the on-road route. Thirty-three healthy, community-living drivers age 65+ years (N=16) and drivers age 20-40 years (N=17) completed both drives. Using non-parametric statistics, results demonstrated that night hazard detection was similar across driving conditions except for time-to-first fixation, which was faster on-road for both age groups (p<.001). At some hazard locations, there were significant differences between the two age groups, with older adults taking longer to initially see hazards. Results suggest, older adults detected hazards similarly to younger adults, especially during on-road performance, suggesting avoidance of night driving may not be necessary. Results also support using driving simulation as a proxy for on-road with night driving needing to be incorporated. Additionally, eye-tracking has the potential for research in hazard detection with emphasis on the time-to-first fixation outcomes when considering driving analysis.

Analysis of the Current State of Automation of Hazard Detection Processes in BIM in Slovakia

Building information modeling (BIM) brings several benefits to design and construction companies, especially in higher efficiency and quality of work. Several companies also use common data environment (CDE) systems, which speed up communication and collaboration between project participants. These can be used for occupational health and safety (HS) purposes and to increase the level of HS on construction sites. The first part of the article presents the state-of-the-art possibilities and approaches to implementing BIM in automatic or semi-automatic health and safety hazard detection. The following parts analyze the interviews with experts in BIM coordination, project management and health and safety in Slovakia and their answers to a survey, that covers the topic of safety hazard detection in BIM. The analysis shows that BIM is a suitable tool for increasing safety on construction sites, but there are several obstacles to achieving its full potential. The survey brings readers closer to the current state of the topic and the possibilities offered by BIM and CDE software in Slovakia. This paper, through the requirements and opinions of experts in BIM, project management and HS management, points out areas for further research and development of BIM software.
