NASHVILLE, Tenn. (WTVF) — With more people in more cars clogging more roads, the city's department of transportation is taking steps to reduce both car crashes and congestion.
NDOT has two projects in the works.
One, they're adding leading pedestrian intervals, or LPIs, to various intersections.

This technology allows people walking to be visible to turning cars. It adds extra seconds for pedestrians to cross, and any car in the turn lane will have a delay.
"Crossing over here could be very dangerous," said one pedestrian Tyler Willis. "Getting across traffic for me is no problem, but I can understand for somebody that's older."
Two, they're retiming light signals. They look at traffic flow at each intersection to find the pattern that best keeps it moving.
NDOT says they've already gotten started on a handful of those projects, and they plan to implement the changes at 336 intersections.

My friend and colleague Carrie Sharp had a lot of fun last week, on an adventure to a country more than three thousand miles away! She’s back now – sharing her Adventures in Iceland through stories, and incredible images of this remarkably beautiful and unique island nation (kudos to Chief Photographer Catherine Steward)! But did you know Nashville has something very important in common with Iceland? Tourism! Here, Carrie explains how a volcanic eruption decades ago helped save the country’s economy from collapse!
