This research aims to develop models predicting fuel consumption and emissions based on vehicle speed and acceleration.
Developed hybrid regression models using instantaneous speed and acceleration as input variables.
Data collected from Oak Ridge National Laboratory included various fuel consumption and emission measurements.
Integrated the models with the INTEGRATION microscopic traffic simulation model.
Models demonstrated high accuracy with coefficients of determination between 0.92 and 0.99.
Utilized to evaluate environmental impacts of operational projects using GPS speed measurements.
Supported assessment of intelligent transportation systems for improved efficiency.
