Improved Modal Operating Profiles for Fuel Use Comparisons among Modes

By ahardingMay 7, 2021Leave a comment

Problem There would be value in discerning a realistic auto operating context/profile to use in comparison with transit travel. We tend to compare mean characteristics of the modes when it…

Assessment of Costs Associated with Hydrogen as an Alternative Fuel

By ahardingMay 7, 2021Leave a comment

Problem Hydrogen has been proposed as a feasible alternative fuel for vehicles. However, the ramifications of such an approach to transportation have not been fully assessed. These include: the emissions due to…

Assessing Inter-City Passenger and Inter- and Intra-City Freight Transport Energy and GHG Intensities

By ahardingMay 7, 2021Leave a comment

Problem Statement Energy intensity values (energy use per unit of activity) are basic data for forecasting, policy analysis, planning, and monitoring progress toward energy and environmental goals. They are essential…

Life Cycle Analysis of Alternative Fuels for Trains, Planes, and Ships

By ahardingMay 7, 2021Leave a comment

Problem Statement The life cycle analysis (LCA) of transportation fuels is a critical step when comparing the energy and environmental attributes of conventional and alternative fuels. LCA accounts for the…

Assessing Direct and Indirect Lifecycle GHG Impacts of Advanced Fuels and Vehicles

By ahardingMay 7, 2021Leave a comment

Problem Statement Regulatory and market pressures are mounting that would encourage a transition of the ground transportation system toward advanced fuels and vehicles. In the US, EPA and NHTSA have…

Driving and the Built Environment Part II

By ahardingMay 7, 2021Leave a comment

Problem Transportation Research Board’s Special Report 298: Driving and the Built Environment: The Effects of Compact Development on Motorized Travel, Energy Use, and CO2 Emissions recommended specific research on the effects…

Effects of Heavy Truck Volumes

By ahardingMay 7, 2021Leave a comment

Problem Statement Among the many types of on-road vehicles traveling the American highway system, heavy trucks are the loudest frequently-heard noise sources. Comments from residents near highways at project public…

Noise and Vibration from Automated People-Movers

By ahardingMay 7, 2021Leave a comment

Problem Statement More than 100 automated people-movers (APMs) of various kinds and sizes now operate around the world. Urban planners, engineers, and architects often consider using APMs to link activity…

Transfer Mobility Measurements and Testing Techniques

By ahardingMay 7, 2021Leave a comment

Problem Statement Transfer mobility measurements are used to help predict vibration and ground-borne noise impacts from transit and rail systems and also to evaluate the effectiveness of vibration mitigation techniques.…

Programming for Reducing the Noise from Corrugations in Transit Rails

By ahardingMay 7, 2021Leave a comment

Problem Statement The operation of steel-wheeled transit vehicles on steel rails may develop short-pitch corrugation of the rails. The interaction of the wheels rolling over the corrugated rails generates noise…
