Develop Multi-scale Energy and Emission Models

The study develops energy consumption and emission models for multiple vehicle modes and rail transit trains in support of environmentally sustainable transportation systems (e.g. eco-routing, eco-driving, eco-transit, eco-freight). Specifically, electric light duty vehicles (LDVs) and trains, conventional diesel, hybrid-electric and compressed natural gas (CNG) buses as well as heavy duty diesel trucks are thoroughly investigated. The models are developed based on Virginia Tech Comprehensive Power-based Fuel consumption Model (VT-CPFM) for fuel-powered vehicles and Virginia Tech Comprehensive Power-based electric vehicle Energy consumption Model (VT-CPEM) for electric energy vehicles and trains. The models can circumvent the bang-bang control in the modeling practice and also can be easily calibrated using publicly available data. The validation efforts are made by instantaneously comparing estimated energy/fuel consumption against field observations and/or the estimates of other state-of-the-art models. The results demonstrate that the proposed models can accurately predict energy/fuel consumption and emissions consistent with field measurements.
