What is the definition of pedestrian crossing according to 49 CFR, Part 218?

The definition of a pedestrian crossing according to 49 CFR, Part 218 is a separate designated sidewalk or pathway where pedestrians, but not vehicles, cross railroad tracks. This definition emphasizes the distinction between areas meant solely for pedestrian use and those where vehicles may also cross.

In this context, option A captures the essence of a pedestrian crossing by indicating that it is specifically designed for pedestrian traffic, thereby enhancing safety by separating foot traffic from vehicular movements. This aligns with regulations that aim to prevent accidents and ensure the safe passage of individuals in the proximity of railroad tracks.

Options that describe an overhead bridge or a crossing where both people and vehicles interact do not comply with the specific criteria set forth in the regulation and thus do not appropriately define a pedestrian crossing as intended in the context of railroad regulations.
