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.

Here’s a beautiful story of how one mother turned her grief journey into a gathering of gratitude… and organ donation awareness.
Robb Coles highlights a special event organized by Cari Hollis – whose 26-year old son Austin died two years ago. Austin agreed to be an organ donor – and that single gesture saved multiple lives.
Cari reached out to as many recipients she could find – several of whom traveled to Nashville for an emotional celebration in Austin’s honor. One woman – whose life was saved by receiving Austin’s lungs – put it simply: “He’s my angel”.
