I-24 MOTION is a first-of-its-kind testbed implemented by the Tennessee Department of Transportation and designed by Gresham Smith in conjunction with Vanderbilt University. Known as I-24 Mobility Technology Interstate Observation Network (or I-24 MOTION), this groundbreaking active testbed runs along the busy and often congested I-24 corridor, and it was designed to allow TDOT and researchers to study how all types of vehicles interact with one another and the state’s infrastructure in order to advance congestion mobility across Tennessee. In essence, it provides an “MRI for traffic” by providing an environment for testing advanced traffic management and automated vehicle technologies in real freeway traffic.
Funded by the Federal Highway Administration Congestion Mitigation and Air Quality Improvement Program, the project transformed a four-mile section of I-24 in the Nashville-Davidson County metropolitan area into an experimental testbed, using over 276 ultra-high-resolution cameras that convert images into a digital model of how every vehicle behaves with unparalleled detail. Over time, the I-24 MOTION project will allow automakers, researchers and TDOT to create, deploy and validate new technologies for connected/automated vehicles and traffic management.
