The Leveraging Advanced Data to Deliver Multimodal Safety (LADDMS) initiative represents a new approach to enhancing the safety of our streets, sidewalks, and bike lanes through cutting-edge technology. 

This project is a collaboration led by the Nashville Department of Transportation and Multimodal Infrastructure (NDOT) in collaboration with Tennessee State University, University of Tennessee Chattanooga, and Vanderbilt University. Together, we're dedicated to identifying and resolving safety concerns that traditional reporting methods might overlook. 

Our focus is on protecting the most vulnerable road users—pedestrians and cyclists. By deploying LiDAR—light detection and ranging technology—we are able to spot and fix safety issues that may not be caught in traditional reports. This data-driven strategy allows us to pinpoint areas of concern and implement targeted solutions to enhance safety for all.
