Abstract Construction sites are dynamic environments where hazard locations and severity change as work progresses. In such settings, real-time risk recognition and movement along safe paths are critical for worker safety. This study extends the Safety Climate Index (SCLI) by developing a simulation environment based on real-time risk levels (RL) to examine worker behavior in dynamic construction sites. The analysis quantitatively evaluates how recognizing and moving through Safety Zones affects individual and site-wide risk levels. Simulation results show that Safety Zone recognition reduced average worker risk by 23.5 percent and decreased high-risk events by more than 80 percent, leading to improved overall site safety. However, task completion rates declined by approximately 33.1 percent due to detours and waiting behaviors, highlighting a trade-off between safety and productivity. The findings suggest that smart safety technologies can support practical accident prevention by encouraging active safety behaviors beyond simple monitoring.
