Developing Procedures for Screening High Emitting Vehicles and Quantifying the Environmental Impacts of Grades
Since the transportation sector is highly responsible for U.S. fuel consumption and emissions, assessing the environmental impacts of transportation activities is essential for air-quality improvement programs. Also, high emitting vehicles need to be considered in the modeling of mobile-source …

Impacts of Energy and Environmental Policies on Air Quality: Bridging Observational Data, Statistical, and Atmospheric Models
… to estimate the average emission factors of vehicles (the relevant outcome for decision making) based on snapshot measurements (the quantity being measured in the field). We find that a much lower fraction of the measured fleet in Europe is in compliance with emission standards compared to …

High Automobile Emissions: Modeling Impacts and Developing Solutions
… dissertation attempts to quantify the impacts of high-emitting vehicles on the environment and to propose solutions to enhance the currently-used high-emitting vehicle detection procedures. In addition, fuel consumption and emission models for high-speed vehicles are developed in order to provide …

Mesoscopic Fuel Consumption and Emission Modeling
… speed and acceleration level as it travels on a highway network. Alternatively, microscopic models capture these transient effects; however, the application of microscopic models may be costly and time consuming. Also, these tools may require a level of input data resolution that is not …
