AERIS 2014 Summer Webinar Series

The United States Department of Transportation (USDOT) announced a series of webinars for its Applications for the Environment: Real-Time Information Synthesis (AERIS) program. The webinars focused on preliminary modeling results for three high priority Operational Scenarios: (i) Eco-Signal Operations, (ii) Eco-Lanes, and (iii) Low Emissions Zones. The webinars were free and open to the public, but interested attendees needed to register in advance for each webinar. 

The 2014 AERIS Summer Webinar Series was offered by the Intelligent Transportation Systems Joint Program Office (ITS JPO). To learn more about the ITS JPO, visit: www.its.dot.gov. Please see the information below regarding the subject matter of each webinar.

June 25, 2014 - Combined Modeling of Eco-Signal Operations Applications: This webinar will describe the combined modeling results for the Eco-Signal Operations Operational Scenario. The Operational Scenario’s objective is to use connected vehicle technologies to decrease fuel consumption and emissions on arterials by reducing idling, reducing the number of stops, reducing unnecessary accelerations and decelerations, and improving traffic flow at signalized intersections. Five applications were modeled: Eco-Approach and Departure at Signalized Intersections, Eco-Traffic Signal Timing, Eco-Transit Signal Priority, Eco-Freight Signal Priority, and Connected Eco-Driving. The AERIS Program recently completed modeling activities demonstrating the potential for fuel use reductions and emissions reductions for each of these individual applications. The purpose of the combined modeling was to investigate the environmental benefits that could be achieved if all five connected vehicle applications were deployed on a signalized corridor. Combined modeling of the applications was conducted for the El Camino Real corridor in California using Paramics traffic simulation software and the Environmental Protection Agency’s MOVES model. This webinar will be used to present the combined modeling results and articulate key findings from the modeling activities.

July 23, 2014 - Preliminary Eco-Lanes Modeling Results: This webinar will describe the preliminary modeling results for the Eco-Lanes Operational Scenario. Eco-Lanes lanes are similar to other managed lanes (such as HOV lanes); however the eco-lanes would be optimized for the environment using connected vehicle data that would allow road operating entities and drivers to be more responsive to real-time traffic and environmental conditions. These lanes would focus on drivers of vehicles seeking to reduce their fuel use or minimize their environmental footprint. The Eco-Lanes also support eco-cooperative adaptive cruise control (ECACC) and eco-speed harmonization applications. This webinar will present the preliminary modeling results and key findings for the ECACC and eco-speed harmonization applications. Modeling of the applications was conducted using Paramics traffic simulation software and the Environmental Protection Agency’s MOVES model.

September 24, 2014 - Preliminary Low Emissions Zones Modeling Results: This webinar will describe the preliminary modeling results for the Low Emissions Zones Operational Scenario. Low Emissions Zones allow for geographic areas (e.g., city center) to restrict or deter access into the area by specific categories of high-polluting vehicles for the purpose of improving the air quality within the geographic area. Low Emissions Zones may also be used to incentivize traveler decisions that are determined to be environmentally friendly such as the use of alternative fuel vehicles or transit. Low Emissions Zones in a connected vehicle environment would be similar to existing low emissions zones deployed today primarily in Europe; however they would leverage connected vehicle technologies allowing the systems to be more responsive to real-time traffic and environmental conditions. The purpose of this webinar is present the preliminary modeling results for the Low Emissions Zones modeling activities. Modeling was conducted using traffic simulation models and Environmental Protection Agency’s MOVES model for a low emissions zone in the Phoenix, AZ metropolitan area.
