Signs and Signals 49. Pedestrian Push
Pedestrian Push Button At locations where pedestrian activity is infrequent and pedestrian signal phasing is not warranted on a full-time basis, the use of pedestrian-actuated signals (i.e., push-buttons) may be justified (figure 5-6). Pedestrian push-buttons are appropriate where occasional pedestrian movements occur and adequate opportunities do not exists for pedestrians to cross.1 Where no pedestrian signals are present, actuation of the push-buttons may be used to extend the green phase to allow pedestrians sufficient crossing time. Push-buttons may also be used with pedestrian signals to provide a quicker WALK interval with extended WALK time for safer pedestrian crossing.3
Pedestrian push-buttons should be mounted 3 1/2 to 4 feet above the sidewalk and placed in a conspicuous, convenient, location,1 preferably next to curb ramps. Such placement will reduce the need for signing to explain which button needs to be pushed to cross the street. Signs such as PUSH BUTTON FOR WALK SIGNAL are needed with the actuation devices to explain their meaning and use. When two actuation devices are placed close together for crossings in different directions (e.g., at intersections), it is important to indicate which crosswalk signal is controlled by each push-button (e.g., PUSH BUTTON TO CROSS SECOND AVENUE). Push-button devices may also be needed on medians and refuge islands where signal timing does not allow pedestrians to cross the complete street width during one signal phase.1,3
Pedestrian safety can be enhanced by pedestrian push-buttons only if they are correctly installed and maintained. Many agencies resist installing pedestrian push-buttons because they are either infrequently used or often used improperly by pranksters wishing to disrupt traffic flow. Problems that have been identified contributing to pedestrian push-button nonuse include the following.6
The following are recommendations to improve the effectiveness of pedestrian push-button devices. 6
