AERIS Fall/Winter 2012-2013 Webinar Series

Webinar 5: Field Study and Modeling Results of a Traffic Signal Eco-Approach and Departure Application

The fifth and final webinar of the AERIS Fall/Winter 2012-2013 Webinar Series will take place on Wednesday, March 13, 2013 at 1:00 pm EST. The webinar will describe the results of a recent connected vehicle field experiment performed in two locations (University of California at Riverside and the Turner Fairbank Highway Research Center). Complementary modeling results will also be described.

The field experiment was conducted in August 2012 and was based on the AERIS Program’s Eco-Approach and Departure at Signalized Intersections application. The field experiment included a roadside equipment (RSE) unit installed at a traffic signal broadcasting signal phase and timing (SPaT) messages using 5.9 GHz dedicated short range communication (DSRC). SPaT messages were received by the in-vehicle application and uses to provide speed recommendations to the driver that encourage “green” approaches to signalized intersections. “Green” approaches include speed recommendations that when applied allow the vehicle to traverse the signalized intersection on green or decelerating to a stop in the most environmentally efficient manner. Results were measured in terms of fuel savings and carbon-dioxide (CO2) emissions reductions. Dr. Matthew Barth, the Director of the University of California, Riverside’s Center for Environmental Research & Technology (CE-CERT), who conducted the study, will lead the webinar.  In addition, Dr. Barth will discuss initial modeling efforts being conducted by the AERIS Program as they relate to Eco-Signal Operations.

Webinar Feedback

In an effort to facilitate feedback from stakeholders on the topics discussed during the AERIS Fall/Winter Webinar Series, the AERIS Program has instituted the AERIS IdeaScale Website. This site is an easy way for webinar participants to post ideas, provide feedback, and exchange opinions about the Webinar content, as well as the AERIS Program in general. Participants are encouraged to utilize this resource to provide your reaction, ideas, and opinions to the AERIS team. The AERIS IdeaScale site can be found at the following location:

In addition, links are provided from the IdeaScale page directly to recordings of the four previous webinars (October 17, November 14, December 12, 2012 and February 13, 2013).

AERIS Fall/Winter 2012-2013 Webinar Series

The United States Department of Transportation (U.S. DOT) is sponsoring a series of webinars for its Applications for the Environment: Real-Time Information Synthesis (AERIS) program. The webinars will review the conclusions of an extensive benefits/cost analysis, three draft concepts of operations devised by the program to describe Transformative Concepts, as well as a summary of the results of an eco-approach field experiment. The webinars are free and open to the public, but interested attendees need to register in advance for each webinar. Each webinar will begin at 1:00 pm Eastern Time and will last approximately 90 minutes. 

The AERIS Fall/Winter 2012-13 Webinar Series is being offered by the Intelligent Transportation Systems Joint Program Office (ITS JPO), which is part of the Research and Innovative Technology Administration (RITA). For more information on the AERIS Program, please visit
