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)
INCEPTION VT v1.0 (data with toolbox)
Wave analysis tools (paper)

WaveX dataset (coming 2025)

I-24 MOTION unlock the potential of traffic science and opportunites for AI

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.

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
- Repeatability Evaluation Package (I led the data analysis)
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...

Field research on traffic measurement

The performance and dynamics of traffic systems can be enhanced by leveraging the integration of various sensing technologies, including camera-based vision systems, radar sensors, LiDAR sensors, and other sensor networks.
