This book was released on 2010-07-30 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Technologies and Approaches to Reducing the Fuel Consumption of Medium- and Heavy-Duty Vehicles evaluates various technologies and methods that could improve the fuel economy of medium- and heavy-duty vehicles, such as tractor-trailers, transit buses, and work trucks. The book also recommends approaches that federal agencies could use to regulate these vehicles' fuel consumption. Currently there are no fuel consumption standards for such vehicles, which account for about 26 percent of the transportation fuel used in the U.S. The miles-per-gallon measure used to regulate the fuel economy of passenger cars. is not appropriate for medium- and heavy-duty vehicles, which are designed above all to carry loads efficiently. Instead, any regulation of medium- and heavy-duty vehicles should use a metric that reflects the efficiency with which a vehicle moves goods or passengers, such as gallons per ton-mile, a unit that reflects the amount of fuel a vehicle would use to carry a ton of goods one mile. This is called load-specific fuel consumption (LSFC). The book estimates the improvements that various technologies could achieve over the next decade in seven vehicle types. For example, using advanced diesel engines in tractor-trailers could lower their fuel consumption by up to 20 percent by 2020, and improved aerodynamics could yield an 11 percent reduction. Hybrid powertrains could lower the fuel consumption of vehicles that stop frequently, such as garbage trucks and transit buses, by as much 35 percent in the same time frame.

Available in PDF, EPUB and Kindle. Book excerpt: Optimizing the road performance of heavy-duty vehicles requires a proper match of driving technique, road, and vehicle. This report describes the development of a simulation program for industry operating personnel that meets the criteria of being user friendly, broadly accessible, and PC compatible. The program was developed as a decision support tool for road vehicle specification and evaluation, modification of existing roads or planning the route of a new one, driver training and upgrading, driver-vehicle-road optimization, and cost calculations.

Download or read book Democratic Legitimacy written by Pierre Rosanvallon and published by Princeton University Press. This book was released on 2011-07-05 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: It's a commonplace that citizens in Western democracies are disaffected with their political leaders and traditional democratic institutions. But in Democratic Legitimacy, Pierre Rosanvallon, one of today's leading political thinkers, argues that this crisis of confidence is partly a crisis of understanding. He makes the case that the sources of democratic legitimacy have shifted and multiplied over the past thirty years and that we need to comprehend and make better use of these new sources of legitimacy in order to strengthen our political self-belief and commitment to democracy. Drawing on examples from France and the United States, Rosanvallon notes that there has been a major expansion of independent commissions, NGOs, regulatory authorities, and watchdogs in recent decades. At the same time, constitutional courts have become more willing and able to challenge legislatures. These institutional developments, which serve the democratic values of impartiality and reflexivity, have been accompanied by a new attentiveness to what Rosanvallon calls the value of proximity, as governing structures have sought to find new spaces for minorities, the particular, and the local. To improve our democracies, we need to use these new sources of legitimacy more effectively and we need to incorporate them into our accounts of democratic government. An original contribution to the vigorous international debate about democratic authority and legitimacy, this promises to be one of Rosanvallon's most important books.
