Which of the following is NOT a responsibility of a roadway worker?

The responsibility of managing all train schedules typically falls under the purview of dispatchers and other operational staff, rather than roadway workers themselves. Roadway workers are primarily focused on the safety and operational aspects of their immediate work environment.

Their responsibilities include maintaining communication with the dispatcher to ensure awareness of train movements and working conditions, determining if proper safety measures are established in their work area, and establishing working limits to ensure that they are not in the danger zone while work is being conducted. Therefore, managing train schedules is not something that roadway workers are expected to handle, making the choice of managing all train schedules an accurate response for what does not fall within their responsibilities.
