What is EAR?

A graphics using oval shaped circles to demonstrate how Exploratory Advanced Research (EAR) is used as a bridge for basic research and applied research.  The left large oval circle is light blue in color and represents basic research with smaller horizontal circles in various colors showing the National Science Foundation (yellow), National and International Laboratories (green), Universities/Centers of Excellence (medium blue), and National and International Transportation Institutes (orange).  Arrows point from the smaller circles to a vertical oval representing EAR, which is on top of a bigger light blue circle representing FHWA mission oriented advanced research. There is a square box with “FHWA Advanced Research Plan” pointing to the middle of the large circle, a round purple circle with “Advanced Transportation Research at DOT, DOE, DOD, EPA, etc” points towards the center of the large blue circle, and a light blue oval circle at the right has “FHWA, NCHRP, State DOT, UTE, Industry” written on it, representing applied research.

Active Traffic Management Research Questions Being Addressed

Post-EAR Action Needs

Cooperative ACC (CACC)

Lead Vehicle Braking, 1.1 s Gap

Stacked photos of vehicles showing a 1.1 second-gap between a test vehicle and traffic ahead using adaptive cruise control (ACC)—top photo—and the same 1.1-second gap between the test vehicle and traffic ahead using cooperative ACC—bottom photo.  The photos are taken from inside the test vehicle looking forward at traffic in front of the test vehicle through the wind shield.

Traffic-Responsive CACC (Using I2V Cooperation)

Post-EAR Action Needs

Automated Truck Platoons

Fuel Saved by 3 Trucks Driving in Close-Formation Platoons

A graphic labeled “average accumulated fuel consumption in cruise period for 3 truck platoon: 1st(b), 2nd(g), 3rd(c).” The Y axis is labeled “fuel consumption in [g]” and ranges from 0 to around 2,150 in increments of 200.  The X axis ranges from 0 to around 370 in increments of 50.  There are three plotted lines.  One line is colored in dark blue, the other is in green, and the last one is light blue. The plotted lines start at the bottom of the graphic at 0, goes to around 70, and then goes to 2,100 and 370 (dark blue), 1,900 and 370 (green), and 1,850 and 370 (light blue) to represent the fuel saved by three trucks driving in close-formation platoons.

3 Truck Platoon (2010)

A video photo image showing a three-truck platoon traveling on a two-lane rural highway.  The lead truck has its headlights on, and the trucks appear to be following in close proximity to the lead truck.  The photo was taken from the front side of the lead vehicle with mountains visible in the background and brown grass and small bushes in the foreground off the road.
