Does the MUTCD allow the use of a “Leading Pedestrian Interval”?
Yes, the leading pedestrian interval (LPI) is now specifically allowed by Section 4E.06 of the 2009 MUTCD. This type of sequence has been used for a long time by a many cities to help pedestrians get a bit of an “edge” over turning vehicles at some locations where they determine it is needed, and its use is increasing. The Pedestrian User Guide published by FHWA and available on the Walkinginfo.org web site indicates that studies have found the LPI has reduced conflicts for pedestrians. The LPI is particularly helpful for older pedestrians who are slower to start into the intersection than other pedestrians, thus giving better notice of their presence in the roadway/crosswalk for right turning drivers. The FHWA Older Driver and Pedestrian Highway Design Handbook recommends the use of the LPI where older pedestrians use the intersection. Return to Top • Q: The 2009 MUTCD now requires pedestrian countdown signals to be used except when the pedestrian change interval is 7 seconds or less.
