Instead of cars driving as individual units on highways, automated driving systems (ADS) allow cars to connect and exchange information, enabling coordinated movements. That can mean more capacity on roads, and faster, more efficient travel.
The study was conducted by experts from the Federal Highway Administration’s (FHWA) Turner-Fairbank Highway Research Center (TFHRC), U.S. DOT’s Volpe National Transportation Systems Center, and the Aberdeen Test Center.
“We are focusing on the cooperative side of automated driving systems,“ said Taylor Lochrane, PhD, Cooperative Automation Research Program technical manager at TFHRC. “If vehicles can communicate with each other and the infrastructure, we can use that capability and coordinate traffic more efficiently and save our economy billions in wasted time and fuel.”
How Automated Driving Systems Enable Car Platooning
For a vehicle to platoon, an onboard computer is connected to a vehicle-to-vehicle communications device that receives and transmits data using Dedicated Short-Range Communications.
“By adding connectivity between cars, we can manage traffic with clusters of vehicles instead of individual vehicles,” said Wassim Najm, PhD, chief of Advanced Vehicle Technology at the Volpe Center. “With better traffic management, we can improve mobility.”
At the Aberdeen site, the test cars successfully shared information, such as whether they needed to speed up or slow down to follow the lead vehicle at a desired distance. Najm’s team piloted the technical and analytical work for testing and evaluating the car platooning proof-of-concept.
“We built the test procedures for the track to test the vehicles using vehicle-to-vehicle communications,” said Najm. “We now have a better understanding of the performance parameters and the test procedures needed for advancing car platooning technology.”
Lochrane’s team programmed the onboard computers with platooning algorithms developed by FHWA and partners from earlier projects. Vehicle computers control braking and acceleration, and also take in radar data—part of adaptive cruise control—to create Cooperative Adaptive Cruise Control.
“The followers follow the vehicle in front and listen to all the other vehicles in the stream and that’s how they all communicate—the computers are able to compute the current and predicted trajectory of the vehicle to maintain their position,” said Lochrane.

Transportation is a lifeline for residents of tribal communities. Residents in these communities often must travel many miles to reach jobs, healthcare and other basic services.
That’s why the Federal Transit Administration (FTA) awarded nearly $5 million in grants to help tribal communities provide public transportation on tribal lands.
FTA’s Tribal Transit Program makes funds available to federally recognized Indian tribes and Alaskan Native villages, groups or communities to support capital projects, operating costs and planning activities for public transportation services on and around Indian Country.
By improving their transit options, tribal communities can better connect residents to jobs, education, healthcare and other services. Learn more about the Tribal Transit Program in our latest video.
The United States’ 100 ports are essential drivers of the American economy providing $1.5 trillion in U.S. foreign trade and nearly 400,000 jobs. The Port of New Orleans (Port NOLA) is a good example of the impact ports have on the nation’s economic growth and sustainability.
I recently had the opportunity to visit Port NOLA to get a firsthand look at their operations. The Port of New Orleans handles about 62 million short tons of cargo a year. To put that into perspective, the amount of cargo that they’ve unloaded could fill the Superdome more than five-and-a-half times.
As we prepare for the holidays, I want to thank you again for welcoming a new team and for your work to advance the Department’s mission for our country. Together, we accomplished a great deal!
WASHINGTON – In late-breaking news, the U.S. Department of Transportation has approved an application submitted by a Mr. Kris Kringle (d/b/a “Santa Claus”) for special air transportation operating authority.
Earlier this month, the Motorcycle Advisory Council (MAC) – a new federal committee created to advise the Federal Highway Administration – met at the National Highway Institute in Arlington, Va., for its inaugural meeting. As directed by Congress, the MAC’s task is to identify engineering-related infrastructure solutions that can reduce fatalities involving motorcyclists. This is no small endeavor. Data compiled by the National Highway Traffic Safety Administration shows that 5,286 of the 37,461 roadway fatalities in 2016 involved motorcycles – representing a 5 percent increase over the previous year.
The MAC consists of ten members selected by the U.S. Secretary of Transportation Elaine L. Chao. These men and women come from across the country and are experts in a wide range of motorcycle-infrastructure topics. Each is a motorcyclist and, combined, the MAC members have over two centuries of riding experience. The meetings are open to the public and, for the first meeting, additional attendees were present including representatives from the American Association of Motor Vehicle Administrators, the Motorcycle Industry Council, Dynamic Research, Harley Davidson, Squire Patton Boggs and the Motorcycle Riders Foundation.
During this busy holiday travel season, there are various resources on the FAA’s and DOT’s websites that will help make your flight safer, smoother, and more enjoyable.
Know Before You Go.
Before going to the airport, always check your airport status and delays. The FAA’s Air Traffic Control System Command Center offers real-time flight delay information at many of the largest airports.
To answer that question, the FAA has advice that will help you pack your bags with safety in mind.
Passengers may not realize that a number of everyday toiletry and electronic items they may pack in their baggage may be considered hazardous material when they’re carried on a plane. E-cigarettes (vaping devices), spare batteries for your electronics, nail polish, hair spray, and other common items are hazardous.
The FAA recommends that passengers carry their portable electronic devices in their carry-on bags whenever possible, instead of in checked luggage. The FAA forbids spare lithium batteries and e-cigarettes in your carry-on luggage. They are always forbidden in checked baggage.
The U.S. DOT’s Volpe Center will welcome Joseph F. Coughlin, PhD, founder and director of the Massachusetts Institute of Technology's Age Lab, on December 13 at noon ET as part of its speaker series The Ongoing Transformation of the Global Transportation System.
The Ongoing Transformation of the Global Transportation System continues the U.S. DOT Volpe Center’s long history of convening thought leaders, decision makers, and stakeholders from across the global transportation enterprise to anticipate future transportation issues, generate fresh approaches to emerging issues, anticipate transportation trends, and inform decision making.
As the private sector drives innovation across all modes, there is potential for dramatic impacts on the safety and efficiency of the future transportation system and the composition of the nation’s transportation workforce.
Register now to join Joseph F. Coughlin of the MIT AgeLab on December 13, by webinar or in person, at the U.S. DOT’s Volpe Center in Cambridge, Massachusetts.
One of my more memorable experiences since becoming FTA acting administrator a few months ago was taking the wheel of a virtual bus as part of a state-of-the-art simulation exercise at the New Flyer Vehicle Innovation Center (VIC) in Anniston, Alabama.
During the October grand opening ceremony of the VIC, a manufacturing lab and training facility for new-technology buses, I drove a simulation bus used for operator training. It opened my eyes to the challenges bus operators face every day, even though my track was mostly obstacle free. Moreover, I took a front seat to the high-tech future of driver training, which should go a long way toward improving safety.
Technology was on display throughout the VIC on the opening day. New Flyer of America, the largest transit vehicle manufacturer in North America, has more than 50 years of experience in manufacturing next-generation buses. The company opened the center, which includes a manufacturing lab, exhibit space, and training areas, to continue to advance bus technology through sustainable research and development.
For several years, New Flyer has produced buses using zero-emission technology, and many of those vehicles populate fleets that have received FTA Low or No-Emission Grants. The program provides funding to state and local governmental authorities to purchase or lease low-emission buses as well as charging facilities and other supportive technology.
New-technology buses are gaining in popularity as agencies realize cost-savings thanks to reduced fuel and lessened maintenance because vehicles run on fewer parts. The changes equate to thousands of dollars over the life of each vehicle. Moreover, they run quietly and emit minimal particulates or carbon monoxide, key components of smog. Passengers report that they enjoy the quieter, odorless travel.
With Thanksgiving only a week away, Americans are in the midst of one of the busiest travel weeks of the year. As millions of passengers take to the skies, DOT is here to help make their trips as smooth as possible. Today, DOT rolled out the first phase of an effort to redesign its airline consumer website to better help air travelers understand their rights. The improved design and streamlined pages will help consumers access needed information before, during, and after their flights now that the busy holiday travel season has kicked off.
DOT believes that an essential part of protecting air travelers is ensuring that they know what their rights are. The pages launched today are just the first step in the Department’s plan to redesign and simplify the aviation consumer information available on its website.
