How should you coordinate pedestrian and vehicle movement in a parking lot?

• A. Pedestrians always have priority
• B. Vehicles always have priority
• C. Use fixed signage only
• D. Rotate the right-of-way between cars and pedestrians so that one group moves at a time

Answer: (D)

In a parking lot, safety comes from creating a predictable, slow, shared-flow environment where both pedestrians and drivers know what to expect. The idea of rotating the right-of-way so that one group moves at a time establishes a clear, intentional sequence: pedestrians cross during designated moments, then vehicles move, and the cycle repeats. This helps prevent surprise moves from either side, reduces the chance of conflicts at crosswalks and between parked cars and through-ways, and is especially useful in tight or low-visibility spots where drivers and walkers might not see each other until the last moment.

Relying only on pedestrians having priority can lead to frequent and abrupt vehicle stops, which increases the risk of rear-end collisions and frustrated drivers. Giving vehicles priority can put pedestrians at risk, especially when visibility is poor or speeds are higher than expected. Fixed signage alone doesn’t adapt to real-time conditions or the actual flow of people and cars in that moment. By coordinating movement in a defined, alternating pattern, the space becomes safer and more manageable for everyone.
