Medium- and heavy-duty trucks, motor coaches, and transit buses - collectively, "medium- and heavy-duty vehicles", or MHDVs - are used in every sector of the economy. The fuel consumption and greenhouse gas emissions of MHDVs have become a focus of legislative and regulatory action in the past few years. Reducing the Fuel Consumption and Greenhouse Gas Emissions of Medium- and Heavy-Duty Vehicles, Phase Two is a follow-on to the National Research Council's 2010 report, Technologies and Approaches to Reducing the Fuel Consumption of Medium-and Heavy-Duty Vehicles. That report
TRB's Airport Cooperative Research Program (ACRP) Report 63: Measurement of Gaseous HAP Emissions from Idling Aircraft as a Function of Engine and Ambient Conditions is designed to help improve the assessment of hazardous air pollutants (HAP) emissions at airports based on specific aircraft operating parameters and changes in ambient conditions.
TRB's Airport Cooperative Research Program (ACRP) Report 60: Guidelines for Integrating Alternative Jet Fuel into the Airport Setting identifies the types and characteristics of alternative jet fuels; summarizes potential benefits; addresses legal, financial, environmental, and logistical considerations and opportunities; and aids in evaluating the feasibility of alternative jet fuel production facilities.
The report also summarizes issues and opportunities associated with locating on- or off-airport alternative jet fuel production facilities and their fuel storage and distribution
TRB's Airport Cooperative Research Program (ACRP) Report 56: Handbook for Considering Practical Greenhouse Gas Emission Reduction Strategies for Airports is designed to assist airport operators in identifying, evaluating, prioritizing, and implementing practical, low-cost strategies to reduce and manage greenhouse gas emissions.
AirportGEAR, an interactive decision support tool developed as a companion to the handbook, considers a range of strategies that can be implemented by all types of airportsâ€"regardless of size, geography, or resourcesâ€"either directly or in partnership wit
TRB Conference Proceedings on the Web 4: Offshore Wind Energy Projects: Summary of a Workshop summarizes a March 2010 workshop held in Washington, D.C., that examined the processes use by the former Minerals Management Service (MMS) for selecting and managing certified verification agents (CVAs) and for identifying appropriate standards for assuring good engineering judgment and practice; for reviewing and approving designs, fabrications, and installations; and for determining acceptable qualifications and role for a CVA associated with nonhydrokinetic offshore renewable energy projects.
TRB's Airport Cooperative Research Program (ACRP) Synthesis 28: Investigating Safety Impacts of Energy Technologies on Airports and Aviation explores physical, visual, and communications systems interference impacts from energy technologies on airports and aviation safety.
The energy technologies that are the focus of this report include the following:
â€¢ solar photovoltaic panels and farms,
â€¢ concentrating solar power plants,
â€¢ wind turbine generators and farms, and
â€¢ traditional power plants.
TRB's Airport Cooperative Research Program (ACRP) Report 46: Handbook for Analyzing the Costs and Benefits of Alternative Aviation Turbine Engine Fuels at Airports consists of the Alternative Fuel Investigation Tool (AFIT), a handbook on the use of AFIT, and a report on its development. AFIT is an analytical model designed to help airport operators and fuel suppliers evaluate the costs associated with introducing "drop-in" alternative turbine engine fuel at airports and the benefits as measured by reduced emissions.
AFIT, which is included in CD-ROM format with the print version of
TRB's Airport Cooperative Research Program (ACRP) Report 48: Impact of Jet Fuel Price Uncertainty on Airport Planning and Development is designed to help airport operators and planners measure the impact of changes in jet fuel price on supply and demand for air service at commercial service airports.
The report includes background research; a computer model, available online and in CD ROM format attached to the printed version of the report; and a user manual. Please note that macros must be ena
TRB's Airport Cooperative Research Program (ACRP) Synthesis 21: Airport Energy Efficiency and Cost Reduction explores energy efficiency improvements being implemented at airports across the country that are low cost and short payback.
TRB's Transit Cooperative Research Program (TCRP) Report 95: Traveler Response to Transportation System Changes, Chapter 19 - Employer and Institutional TDM Strategies pair-uses wise comparisons to explore the relative importance of particular categories of TDM strategies, such as support versus incentives, as well as the particular strategies themselves, such as transit subsidy versus a high-occupancy vehicle parking discount.
TDM (transportation demand management or travel demand management) is a process that can encompass a variety of measures intended to influence travel choic
