I-24 MOTION testbed
Testbed for traffic management and automated vehicle technologies
Located on 4 miles of Interstate 24 in Middle Tennessee (near Nashville)
The I-24 Mobility Technology Interstate Observation Network (MOTION) is a four-mile section of I-24 in the Nashville-Davidson County Metropolitan area with 276 ultra-high definition cameras. Those images are converted into a digital model of how every vehicle behaves with unparalleled detail.
I-24 MOTION released data and toolbox
INCEPTION v1.0.0 (our first trajectory dataset)
I-24 MOTION unlock the potential of traffic science
Leslie C. Edie, Robert Herman, Robert E. Chandler, Denos Gazis, Elliott W. Montroll, Refrey B. Potts, and Richard W. Rothery opened up this direction since 1956.
Understanding stop-and-go waves
Field experiments t0 smooth traffic
The I-24 MOTION testbed has offered opportunities to evaluate various ITS and CAV technologies for traffic smoothing. Since the launch of the testbed, I've been involved in several experiments, including:
CIRCLES Mega Vanderbilt Test (MVT) - November, 2022
VSL deployment, I-24 SMART corridor phase 2 - June, 2023
SAILing CAVs (lead by Matt Nice) - August, 2023
MW experiment (lead by Matt Nice) - October, 2023
One4All prototype testing (first experiment I lead) - December, 2023
Class project for world's first CAV practice class Autonomous Vehicle & Traffic
Philosiphy is to use 1 pilot vehicle as sensor to help the upcoming traffic control the speed
Challenges lie in the V2V development, speed control policy...
