Construction site hazard recognition skills measurement via eye-tracking and immersive virtual reality technologies

Özel, Bekir Enes
Hazard recognition is considered as one of the major elements of construction site safety; however, empirical studies about hazard recognition capabilities of construction workers are limited due to nature of construction sites and difficulty of measuring this skill. This study suggests usage of immersive virtual reality systems, eye tracking, and game technologies to overcome this difficulty. In this scope; a virtual construction site with hazardous situations was designed and used in experiments, via these technologies. In these experiments, effects of levels of formal education and work experience on hazard recognition rate and speed were tested. The results show that level of education has a significant effect on hazard recognition performance. Both recognition rate (p=0.000058) and speed (p=0.021) are significantly better for more educated group of workers. Moreover, the difference in recognition rate is mostly caused by the hazards which were seen but unrecognized by the subjects. On the other hand, experience does not affect hazard recognition performance. Neither recognition rate nor recognition speed is different among the groups. However, the ratio of the unseen hazards is significantly higher (p=0.004) for more experienced group of workers. Additionally, results are also analyzed according to each hazard individually. The contributions of this study are on two fronts: Firstly, the results obtained would broaden the knowledge on hazard recognition behavior and they could help developing better and more personalized safety management and training strategies. Secondly, the methodology suggested in this study provides a practical, ethical, and feasible way of conducting safety research.


Potential of Biosensors as Indicators of Safe Behavior in Construction Sites
Özel, Bekir Enes ; Pekeriçli, Mehmet Koray (2020-11-12)
Maintaining the safe behavior of construction workers is one of the major aspects of safety management in the AEC industry. Unsafe behavior in hazardous places like construction sites could lead to severe consequences. Meanwhile, measuring and controlling safe behavior is an ambiguous task. Unsafe behavior can have various reasons. It is a very complex issue that includes many hard-to-measure variables. Yet still, most of the time, understanding and analyzing these reasons are done merely ba...
Fuzzy-based escape route fire-vulnerability assessment model for indoor built environment
Kızılkaya Öksüz, Nilüfer; Tanyer, Ali Murat; Pekeriçli, Mehmet Koray (2022-02-01)
Fire safety evaluation is rarely involved in the iterative building design process except for legislative approval phases compared to other building objectives. However, regardless of architectural design priorities, all buildings should have adequate fire protection. This research develops a fire vulnerability assessment model based on the impact of architects on fire protection and effects of building design characteristics on fire safety. Inherent to the uncertain nature of fire safety evaluation practic...
Using the balanced scorecard as a safety management tool in construction companies : a qfd approach
Şimşek, Burak; Gündüz, Murat; Department of Civil Engineering (2006)
The aim of this thesis is to propose a safety management framework for construction companies. A literature review was performed to identify significant factors that would improve safety performance. Two management tools are used within the scope of this study: the balanced scorecard and quality function deployment (QFD). Strategic goals are established for each perspective of the balanced scorecard: financial and cultural, employee, process and learning and growth. Afterwards, a questionnaire was prepared ...
Designing Buildings to Cope with Emergencies: Findings from Case Studies on Exit Preferences
Sagun, Aysu; Anumba, Chimay J.; Bouchlaghem, Dino (MDPI AG, 2013-6-18)
Static information found in current building design guidance documents is not adequate to achieve efficient safety and security in public buildings during emergencies. There is a need to consider space characteristics and dynamic information related to building use, behavior and movement of users in various circumstances, as well as their interactions with each other and with their immediate environment. This paper explores the building design issues associated with safety and security and focuses on the ex...
A system approach to occupational health and safety management
Gözüyılmaz, Cem; Esin, Alp; Department of Mechanical Engineering (2003)
In this thesis, methods used at present in occupational health and safety management are analyzed and a model safety management system is developed. History, development and recent occupational safety regulations in the United States of America and European Union are introduced to give a sight on this subject in developed countries. The suggested model is evaluated with work accident data taken from a company and hazard and risk analysis methods are used to investigate these accidents. Preventive measures t...
