What does the acronym PTC stand for in roadway worker safety?

The acronym PTC stands for Positive Train Control, which is a safety system designed to prevent train accidents caused by human error. In the context of roadway worker safety, PTC plays a crucial role in enhancing the protection of workers by ensuring that trains can be accurately monitored and controlled, minimizing the risk of collision or other dangerous incidents. This technology integrates GPS tracking, sensing systems, and onboard computers to automatically adjust train speeds or stop trains in potential hazard situations. Understanding PTC is essential for roadway workers as it directly impacts their safety measures and operational procedures when working near train tracks or in environments shared with trains.
