What is the ideal minimum duration for a pedestrian walking phase at a signalized intersection?

The ideal minimum duration for a pedestrian walking phase at a signalized intersection is 7 seconds. This duration is based on the average walking speed of pedestrians, which is generally considered to be around 3.5 feet per second. In pedestrian facilities, the minimum walking time calculation typically allows enough time for individuals to safely cross the intersection without rushing, thus enhancing safety for all users.

For many signalized intersections, this 7-second duration accounts for the distance that a pedestrian needs to cover when crossing the street, taking into consideration various factors such as the width of the intersection and the demographics of the pedestrian population, which may include children, the elderly, and those with disabilities who may require additional time. Providing at least 7 seconds as a minimum ensures that a larger proportion of pedestrians can comfortably start and finish their crossing while minimizing the potential for conflicts with turning vehicles.

Overall, this consideration is essential in designing pedestrian-friendly environments and ensuring compliance with guidelines and regulations aimed at safeguarding pedestrian mobility.
