Strategic Study of CAE 2010, Volume 12, Issue 3,   Pages 68-72

Abstract:

This paper aims to explore the tracking approach of safety hazards and real-time-prediction methods of safety risks on construction sites. A literature review of safety issues on construction sites is first conducted. Consequently, a schematic model of tracking safety hazards and real-time prediction of safety risks is formulated and the corresponding methodologies are summarized. This study would provide a possible research approach on method for tracking safety hazards and real-time prediction of safety risks, while serving as a foundation for further study by drawing researchers' attention to the precursor signals of safety hazards on construction sites.
