    TUCSON, Ariz. (KGUN) — The Tucson Department of Transportation is trying different things to keep pedestrians safe.

One of the newest experiments is the only crossing of its kind downtown. It’s called a leading pedestrian interval (LPI).

For three seconds, all traffic lights are red to drivers, creating safer intersections.

“It gives the pedestrian a head start into the crosswalk,” said Michael Graham with TDOT. “They’re visible to the motorists before the motorists turn into the intersection.”

The LPI intersection is at Broadway and Stone because there are a higher number of pedestrians using it. TDOT says it may roll this type of configuration out to other city intersections after a three to four-month trial.
