NDOT devices capture near-miss traffic data in Nashville

The Nashville Department of Transportation has installed the first of several LiDAR devices in North Nashville with the goal of collecting data that can be turned into safety improvements for drivers and pedestrians.

LiDAR (Light Detection and Ranging) devices emit lasers that map objects three dimensionally. They’re different from cameras in that they’re not capturing images of individuals or their faces.

“I think the key point that we’re trying to make with the community is that this is not surveillance technology,” said NDOT Chief Traffic Engineer Derek Hagerty. “Cameras certainly have their place for safety. But these LiDAR devices give us the ability to capture a lot of the same information through an anonymous system.”
