To improve worker safety in High Speed Temporary Traffic Control Zones, which factor is essential?

Rerouting traffic around the work site is essential for improving worker safety in High Speed Temporary Traffic Control Zones because it reduces the risk of accidents involving vehicles and workers. When traffic is diverted away from the work area, it minimizes the chance of interactions that could lead to dangerous situations. Less vehicle traffic in proximity to workers means a lower risk of collisions, which is particularly important in high-speed environments where the potential for severe injuries is significant.

In contrast, options such as installing speed bumps, providing free refreshments, or setting up additional signage may not effectively address the immediate safety concerns posed by high-speed traffic. While these options could potentially contribute to worker safety in a limited capacity, they do not provide the same level of protection as rerouting traffic, which fundamentally changes the dynamics of the work environment by removing hazards altogether. This makes rerouting traffic the most effective strategy in ensuring worker safety in these high-risk zones.
