Investigation of Factors Impacting Situation Awareness of Highway Workers and Applicable Warning Methods
Publication: Construction Research Congress 2022
ABSTRACT
Dynamic worksite conditions and proximity to live traffic frequently expose highway workers to unsafe proximities, resulting in accidents. Improving workers’ situation awareness is one of the measures to prevent worksite injuries. The research investigates factors that impact workers’ situation awareness in highway work zones and explores applicable human-centered hazard warning methods under various worksite scenarios. To this end, two surveys were conducted with construction workers and managers. The first survey aims to compare the participants’ perception of worksite injuries, safety management, and the company’s safety culture. It also investigates the difference of perception between workers and managers that contributes to unsafe behaviors. The second survey investigated workers’ hazard detection ability under various work zone conditions, warning alarm methods preference, and wearable warning device location preference. The research looks into situation awareness from multiple aspects and provides helpful advice for human-centered alarm design based on highway workers’ experiences. The results provide a useful reference for wearable PPE design to improve roadway worksites’ safety levels.
