Which of the following should be checked to ensure traffic control effectiveness?

The arrangement and clarity of signage is vital for ensuring traffic control effectiveness because clear and well-placed signs communicate important information to drivers and pedestrians about the work zone conditions. Effective signage helps in guiding traffic safely around the work area, reducing confusion and potential accidents. It is essential that the signage is not only visible but also easy to understand, allowing motorists to respond appropriately to the changing conditions caused by construction activities.

Effective traffic control relies heavily on the visibility and understanding of the provided signs. Factors such as placement, size, and illumination all contribute to how effectively the signage can relay important messages to the traveling public. By ensuring that signage is properly designed and situated, traffic can be appropriately managed, enhancing safety for both workers and motorists. This aspect is a fundamental part of establishing a successful work zone traffic control plan.
