What kind of signal is often used during high pedestrian traffic periods?

A dedicated pedestrian signal is specifically designed to indicate when it is safe for pedestrians to cross the street. These signals provide clear visual cues, such as a "Walk" symbol or a countdown timer, that help pedestrians make informed decisions about when to cross. During periods of high pedestrian traffic, these signals enhance safety by ensuring that pedestrians have exclusive use of the crosswalk, thereby reducing the risk of accidents involving vehicles.

In contrast, other types of signals may not offer the same level of clarity or safety for pedestrians. Flashing red lights typically require drivers to stop and yield but may not indicate a designated crossing period. General green lights signal that vehicles may proceed, which can create confusion and dangerous situations for pedestrians if there is no dedicated crossing signal in place. A yellow caution light warns drivers to slow down and prepare to stop, but it does not provide any specific instruction for pedestrians. Therefore, the use of a dedicated pedestrian signal is crucial in managing pedestrian crossings effectively during periods of high foot traffic.
