Eco Approach and Departure (Eco-AnD) is a Connected Automated Vehicle (CAV) technology aiming to reduce energy consumption for crossing a signalized intersection or set of intersections in a corridor that features vehicle-to-infrastructure (V2I) communication capability. This research focuses on developing a Dynamic Programming (DP) based algorithm for Chevrolet Volt Gen II operating in Charge Depleting mode. The aim of such an algorithm is to find a global optimal velocity trajectory for crossing a signalized corridor while accounting for vehicle powertrain dynamics as well as road dynamics. The simulation results are presented for a real-world intersection and energy benefits are shown by comparing against a simulated human driver speed profile. Initial simulations reflect an energy saving potential of 80-110 kJ for a single intersection crossing of 300 m approach and departure distance each.
