What is the design speed for pedestrians in typical urban timing calculations?

• A. 3.0 ft/s
• B. 4.0 ft/s
• C. 3.5 ft/s
• D. 2.0 ft/s

Answer: (C)

In urban timing calculations for pedestrians, engineers use a standard walking speed that represents a typical, comfortable pace for most pedestrians. That speed is 3.5 feet per second, which is about 2.4 miles per hour. This value lets you convert crosswalk length into a realistic crossing time using time = distance / speed. It keeps signal timing practical for the average pedestrian without making the walk too long or too short. Slower speeds would make crossing times unnecessarily long, while faster speeds would risk not accommodating slower walkers. So 3.5 ft/s is the standard used in these calculations.
