A Methodology for Estimating Greenhouse Gas Emissions from Heavy Duty Diesel Trucks Used for Road Transportation in the Construction Sector
A large growth in the number of Heavy Duty Diesel Vehicles (HDDVs) is one of the main causes that Greenhouse Gas (GHG) emissions from the road transportation experienced a significant increase since 1990. With 97.5% of the total fleet used for delivery being HDDVs, these vehicles play an important …

Multi-modal Energy Consumption Modeling and Eco-routing System Development
… for on-road vehicles. Given that gasoline light duty vehicles (LDVs) and electric vehicles were modeled in previous studies, the research effort mainly focuses on heavy duty vehicles (HDVs). Specifically, heavy duty diesel trucks (HDDTs) as well as diesel and hybrid-electric transit buses are …
