COUNTERMEASURE COUNTERMEASURE Extend Pedestrian Crossing Time Pedestrian Phase Recall Increases time for pedestrian walk phases, Signals can be put in “recall” full time or especially to accommodate vulnerable for key time periods of day such as peak populations, such as children and the elderly. business hours or school drop-of /pick-up times. During these periods the “WALK” signal would be displayed every signal cycle without prompting by a pedestrian push button.

SIGNAL TIMING & PHASING COUNTERMEASURE Pedestrian Scramble A form of pedestrian "WALK" phase at a signalized intersection in which all vehicular trafc is required to stop, allowing pedestrians to safely cross through the intersection in any direction, including diagonally. Locations: Signalized Intersections Note: identified as "Implement Barnes Dance" in CMF Clearinghouse. COUNTERMEASURE Reduce Cycle Lengths Trafc signal cycles should be kept short (preferably 90 seconds maximum) to reduce pedestrian delay. When delay is significant, pedestrians are more inclined to ignore signal indications. Locations: Signalized Intersections Note: not in CMF Clearinghouse.
