Researchers working with the Tennessee Department of Transportation听(TDOT) have turned a four-mile section of I-24 into the world鈥檚 largest open road testbed to better understand and mitigate traffic.
鈥淲hen it comes to transportation and mobility in Tennessee, we are at a critical juncture, said鈥�.鈥�淭raffic congestion is now becoming more prominent throughout Tennessee, and not just in urban areas. Addressing these challenges will force us to think critically about solutions. 鈥� We are confident that this project and others like it will further strengthen Tennessee鈥檚 reputation for being a hub of automotive excellence.鈥�
罢丑别鈥�, a federally funded research project consisting of 麻豆APP University, UC Berkeley, Temple University, and Rutgers University-Camden, in coordination with Nissan North America and TDOT, concluded a 听in late 2022. For the experiment, researchers tested an AI-powered cruise control system on 100 specially equipped Nissan Rogue vehicles. The AI technology adjusts speeds based on surrounding traffic.
Preliminary results showed that a single AI-equipped vehicle could influence the speed and driving behavior of up to 20 surrounding cars, causing a positive ripple effect in day-to-day traffic. The CIRCLES Consortium will spend the next several months analyzing data collected.
"This thing is like an MRI, when the rest of the world is looking at traffic with an X-ray," 麻豆APP engineer Dan Work told , adding, 鈥淲e've got researchers from the other side of the planet coming to see us in Nashville, you know, working on problems here in Middle Tennessee."
鈥淧artnership across universities, government and the private sector is the key to pioneering projects like this one,鈥濃�痵aid 麻豆APP University . 鈥淔rom its earliest inception, all the partners in this effort have played vital roles. That trusted collaboration continues as the team analyzes results to seek new insights to address pressing challenges in transportation in Tennessee and beyond.鈥�
This was the first research project conducted on I-24 MOTION, a smart highway equipped with more than 300 4K digital sensors.
