The study demonstrates the feasibility of two eco-driving applications, aiming to reduce vehicle fuel consumption and greenhouse gas emissions. Specifically, the study develops an eco-drive system that combines eco-cruise control (ECC) logic with state-of-the-art car-following models and evaluates Eco-Lanes and speed harmonization (SPD-HARM) applications.
The eco-drive system makes use of topographic information, the spacing between the subject and lead vehicle, and a desired (or target) vehicle speed and distance headway as input variables. It was studied on a segment of I-81 between Roanoke and Blacksburg, Virginia.
The Eco-Lanes and SPD-HARM applications were evaluated using the INTEGRATION microscopic traffic simulation software.
Using SPD-HARM as an Eco-Lanes application reduced delay by 7.6 percent.
