What is it called when only pedestrians are allowed to move at an intersection?

The term for a situation where only pedestrians are allowed to move at an intersection is known as exclusive pedestrian phasing. This concept is implemented in traffic signal systems to enhance pedestrian safety by ensuring that vehicles are stopped while pedestrians have the right of way to cross the intersection. During exclusive pedestrian phasing, the signals are designed to prevent any vehicular movement, allowing pedestrians to navigate the intersection without the risk of interacting with traffic, which helps reduce potential accidents and improves the flow of foot traffic.

The other options do not accurately describe this specific traffic management strategy. Traffic halt, while it might imply stopping vehicles, does not specifically indicate pedestrian priority. Pedestrian only zone suggests a broader area restricted to pedestrians rather than just the controlled timeframe at an intersection. Crosswalk operation refers to the general functioning of crosswalks and may include various traffic scenarios rather than exclusively prioritizing pedestrians. Therefore, exclusive pedestrian phasing precisely captures the essence of this traffic regulation.
