I-24 MOTION implementation underway
The Tennessee Department of Transportation (TDOT) is implementing a first-of-its-kind testbed to understand how all types of vehicles interact with each other and the state’s infrastructure in order to advance congestion management. This testbed is known as the I-24 Mobility Technology Interstate Observation Network, or I-24 MOTION.
This project will equip a six-mile section of I-24 between Nashville and Murfreesboro with over 300 ultra-high definition cameras, converting those images into a digital model of how every vehicle behaves with unparalleled detail. This is all done anonymously using Artificial Intelligence (AI) trajectory algorithms developed by Vanderbilt University. Vehicle trajectory data allows new insights into how traffic flow influences individual vehicle behavior. This groundbreaking understanding of traffic is more important than ever due to the increasing automation capability of individual vehicles, which are beginning to influence traffic flow through their interactions with conventional vehicles. By unlocking a new understanding of how these vehicles influence traffic, vehicle and infrastructure design can be optimized to reduce traffic concerns in the future to improve safety, air quality, and fuel efficiency.
Using the information gathered on this testbed, I-24 MOTION will provide insights to allow the industry to build better products and allow TDOT to better understand how to make the most out of these products for managing infrastructure assets. TDOT envisions additional opportunities to pursue mutually beneficial uses of the testbed with industries such as those outlined below.
- Automotive Original Equipment Manufacturers and Suppliers
- Traffic Simulation Software Developers Freight and Logistics Operators
- Infrastructure Owners
- Intelligent Transportation Systems (ITS) Product Manufacturers
The design and construction of the entire testbed are forecasted for 2021-2022.
