1 Hao, Wu, Boriboonsomsin, and Barth. 2 The connected vehicle Eco-Approach and Departure (EAD) application for signalized intersections has 1 been widely studied and is deemed to be effective in terms of reducing energy consumption and both 2 greenhouse gas and criteria pollutant emissions. Prior studies have shown that tangible environmental 3 benefits can be gained by communicating the signal phase and timing (SPaT) information of the upcoming 4 traffic signals with fixed time control to the

Based on the framework 6 previously developed by the authors, real-world testing has been conducted along the El Camino Real 7 corridor in Palo Alto, California to evaluate the system performance in terms of energy savings and 8 emissions reduction. Strategies and algorithms are designed to be adaptive to the dynamic uncertainty for 9 actuated signal and real-world traffic. It turns out that the proposed EAD system can save 2% energy for all 10 trips, and 6% energy for the trip segments within DSRC ranges of road-side units under light traffic 11 conditions. The proposed system can also reduce 7% of CO, 18% of HC and 13% of NOx for all trips. 12 Those results are compatible with the simulation results and validate the previously developed EAD 13 framework. 14 15 16 17
