Microscopic Fuel Consumption and Emission Modeling
… models to predict vehicle fuel consumption and emission metrics are presented in this thesis. Vehicle fuel consumption and emissions are complex functions to be approximated in practice due to numerous variables affecting their outcome. Vehicle energy and emissions are particularly sensitive to …

Mesoscopic Fuel Consumption and Emission Modeling
… a major contributor to U.S. fuel consumption and emissions. Consequently, assessing the environmental impacts of transportation activities is essential for air-quality improvement programs. Current state-of-the-art models estimate vehicle emissions based on typical urban driving cycles. Most of …

Development of a Microscopic Emission Modeling Framework for On-Road Vehicles
… since it is a major vehicle fuel consumption and emissions contributor. These emissions are considered a major environmental threat. Consequently, decision makers desperately need tools that can estimate vehicle emissions accurately to quantify the impact of transportation operational projects on …

Integrated Assessment of Structural Change and Sustainability in the Chicago Region
… systems are becoming stronger, regional economic modeling is necessary to reflect the recent structural changes of economy and the nature of environmental component. Another issue is that the uncertainty and errors exist in data, assumptions and estimations in regional economic modeling. This …

Estimating life cycle carbon emissions of the global oil supply chain at a high-resolution using optimization in a network model
… backdrop, there is an increasing push for better emissions reporting throughout the supply chain and regulatory mandates at making climate friendly choices. Notable examples include the Low Carbon Fuel Standard by the California Air Resources Board [2] and the Fuel Quality Directive by European …

Quantifying the Impact of Traffic-Related and Driver-Related Factors on Vehicle Fuel Consumption and Emissions
… the dominant source of U.S. fuel consumption and emissions. Specifically, highway travel accounts for nearly 75 percent of total transportation energy use and slightly more than 33 percent of national emissions of EPA's six Criteria pollutants. Enactment of the Clean Air Act Amendment of 1990 …

Enhancements to Transportation Analysis and Simulation Systems
… Generator, Route Planner, Microsimulator, Emissions Estimator, and Feedback. This package has been under development since 1994 and needs significant improvements within some of its modules. This dissertation enhances the interaction between the Route Planner and the Microsimulator modules …

Modeling and simulation of vehicle emissions for the reduction of road traffic pollution
… citizens travel there daily for various reasons. Emissions released by transport fleets have an exhaust (tailpipe) and a non-exhaust (brake wears ) origin. Both exhaust and non-exhaust airborne particles can have destructive effects on the human cardiovascular and respiratory systems and even lead …

Mitigating negative transport externalities in industrialized and industrializing countries
… and compares the effect of congestion pricing on emissions levels and the effect of emission pricing on congestion levels while considering heterogeneity in the individual attributes and choice behavior. Derived from the inter-relationship between the two externalities, a joint internalization of …

Modeling of N2O emission from unmanaged terrestrial ecosystem soils
… processes. Current estimates of N2O emissions on regional to global scales are largely based on the upscaling of limited measurements from specific measurement sites. These estimates have large uncertainties because of the heterogeneity of soils and the seasonal and inter－annual …
