Abstract:The project aims to using eye-tracking technology to optimize the work zone safety. Firstly, a systematic literature review was conducted to present the background of its application in construction safety. In total, 81 publications were screened from Web of Science (WoS), Scopus, and American Society of Civil Engineers (ASCE) library. A statistical analysis was conducted from time-series, location, publication and co-author analysis. The procedures of the research were summarized, including how to recruit participants, design of experiment and eye-tracking metrics. Opportunities and challenges of the technology on construction safety were also presented. Then, the project revolved around three research aims: (1) test the elements that can influence workers’ hazard identification rate (HIR); (2) verify whether the immediate training is efficient in improving workers’ HIR; (3) illustrate whether the safety training has an effect on visual search strategy for different groups. The result shows that the field of study can influence workers’ HIR but safety training certificates and related jobs work experience cannot. A brief safety training affects the high-HIR rate and low-rate groups differently. It recommends that the organization adopts various safety training methods to improve workers' visual search strategy.
