Evaluating road work site safety management: A case study of the Amman bus rapid transit project construction
Abstract
AbstractThis study explores safety perceptions in Jordan’s road construction sites, where work-zone hazards have been insufficiently addressed despite extensive research elsewhere. The study focuses on the impact of safety measures on workers and their environment, providing in-depth insights into roadway construction projects’ safety climate. The study analyzed responses from the Project-Based Group (PB) and the General-Based Group (GB). The PB group included 75 subjects interviewed face-to-face, while the GB group had 43 subjects who filled out an online form. The ratings indicate that staff training, traffic operations, loading/unloading, and site administration safety measures are perceived positively. However, there is a need to improve general site safety and maintenance/management protocols. Safety perceptions differ significantly between the PB and GB groups across multiple safety factors. While the response rates are similar to some extent, differences in safety measure evaluations emphasize the need for targeted interventions. The study highlights the importance of standardized safety protocols, particularly in areas like general traffic safety and maintenance. Using Exploratory Factor Analysis (EFA), the research identifies nine factors that shed light on safety perceptions. Sociodemographic elements such as age, job roles, education, and representation significantly impact perceptions. The correlation analysis reinforces the association of factors. The Confirmatory Factor Analysis model (1st and 2nd order) confirms a strong association between the latent and observed variables. However, some model fit criteria were still unmet, signaling the need for further refinement. Despite challenges, the research provides valuable insights into construction safety perceptions, guiding future research.
