What priority level should railroad preemption be set to?

Railroad preemption should be set to the highest priority level. This is crucial because railroad crossings are critical points where vehicular and train traffic intersect, and the safety of both motorists and train passengers must be prioritized. When a train approaches, the traffic signal at the intersection must change to ensure that vehicles are cleared from the track to prevent collisions.

Setting the priority to the highest level ensures that the signals respond promptly to approaching trains, significantly reducing the risk of accidents. The quick response time is essential for the safety of all parties involved, as even a slight delay can have catastrophic consequences.

In traffic signal management, the integration of railroad preemption into the overall traffic signal system reflects the inherent risks associated with train operations. By adhering to highest priority levels for railroad preemption, traffic control devices can maintain an effective operation that prioritizes public safety above all other considerations.
