Abstract:
The Manual of Uniform Traffic Control Devices (MUTCD) has long used 4.0 ft/sec as the recommended walking speed to be used in setting the time for the pedestrian clearance (Flashing Don’t Walk) phase for pedestrian signal installations. Recently, the National Committee on Uniform Traffic Control Devices voted to change the recommended walking speed to 3.5 ft/sec for the pedestrian clearance phase, and 3.0- ft/sec for the entire Walk/Flashing Don’t Walk interval. This paper will give the history of the 4.0 ft/sec walking speed, going back to the 1961 MUTCD, and then explain the rationale for the new MUTCD recommendations.
