Streetfilms: What’s an LPI?
3:53 PM EDT on July 18, 2008
A leading pedestrian interval, or LPI, lights up the pedestrian signal a few seconds before vehicular traffic gets the green. This gives pedestrians
a head start into the intersection and makes it less likely that they will be hit by vehicles turning into the crosswalk. LPI’s are also known by their sassier nickname, Pedestrian Head Start. But in my view the best variation on what LPI stands for comes from Christine Berthet of the Hell’s Kitchen Neighborhood Association, who proposes “Life Preserving Interval.”
Transportation Alternatives has recently begun a push to make these more common in New York City. Here’s hoping our video (featuring some nice visuals from TOPP’s own Carly Clark) can help argue the case.
Clarence Eckerson Jr. is the Director of Video Production for NYCSR's StreetFilms and producer of bikeTV. He loves the color purple, chocolate chip cookies, and enjoys walking, biking, and taking transit. He has never owned a driver's license.
