The development of Connected and Automated Vehicles (CAVs) has inspired applications designed to improve existing transportation systems. Connected eco-driving, where drivers are guided to approach and depart from signalized intersections in a way that minimizes unnecessary emissions, takes advantage of Signal Phase and Timing (SPaT) information from traffic signals to communicate with CAVs. Simulation models show emissions reductions of between 10 and 15 percent. However, implementations involving real vehicles are not very common.
Using the US EPA's MOVES model, the researchers concluded that the connected eco-driving system provided nine percent fuel savings in the acceleration scenario and four percent fuel savings in the deceleration scenario.
