PHILADELPHIA-- Philadelphia Mayor Michael Nutter used April Fools' Day to have a little fun with what he says is a real problem - distracted walking.

City officials painted lines and oblivious stick-figure pictures on one stretch of John F. Kennedy Boulevard near City Hall as a jab at pedestrians who keep their eyes on their cellphones and not their surroundings.

The lines and "e-lane" sidewalk graphics - depicting a pedestrian peering down at a hand-held device - will stay in place for about a week.

A bogus video released for the new lanes includes Nutter being cut off by an oblivious pedestrian, played by Streets Department Deputy Commissioner Steven Buckley.

All kidding aside, Deputy Mayor Rina Cutler says distracted pedestrians are a serious issue the city plans to address.
