Available in PDF, EPUB and Kindle. Book excerpt: Vehicular fuel consumption and emissions are two increasingly important measures of effectiveness of sustainable transportation systems, particularly considering that mobile sources in the U.S. account for the largest consumption of energy and generation of air pollution. Improving the energy efficiency of the transportation sector including improving vehicle shape, weight, engine size, and tire quality could play a vital role in reducing fuel consumption and exhaust gas emissions. Pavement surface type and other surface characteristics such as skid resistance and roughness affect vehicular fuel consumption. The main objective of this study has been to investigate any differences that might exist in fuel consumption when operating an instrumented van on an Asphalt Concrete (AC) versus on a Portland Cement Concrete (PCC) pavement under city driving conditions. The overall study goal has been to recommend consideration of such user costs or savings in the life cycle analysis of alternative pavement designs for city streets. Fuel consumption measurements were made on multiple runs under two driving modes: 30-mph constant speed and 3-mph/sec acceleration for 10 seconds. All factors that could affect fuel consumption, other than the pavement surface were either controlled or kept the same during the measurement runs. Those factors included speed, ambient temperature, relative humidity, wind speed and direction, vehicle weight, tire pressure, and use of auxiliary devices in the vehicle. The results indicated that the differences in fuel consumption rates were statistically significant at a 10% level of significance under both constant speed and acceleration modes, with the fuel consumption rates on the PCC pavements being lower. The extrapolated results also indicated that if all the annual vehicle miles of travel in the Dallas-Fort Worth region took place at a constant speed of 30 mph on PCC pavements, the statistically lower fuel rates could result in an annual savings of about 401 million gallons of fuel and an annual CO2 reduction of about 3.53 million metric tons. Using an average gasoline price of about $3.29 per gallon and an average CO2 clean-up cost of about $18 per metric ton, these differences would amount to a savings of about $1.38 billion per annum in the DFW region. The potential savings or costs in fuel consumed and the CO2 emissions generated can be substantial over the design life of a road project. It is therefore recommended that these savings or costs be considered in the life cycle cost analysis of alternative road construction projects.

Available in PDF, EPUB and Kindle. Book excerpt: The relationship between components of vehicle operating costs (VOCs) and highway characteristics has been studied by many researchers over the years, but many issues still remain to be resolved. In particular, although fuel consumption should be the easiest component to model, there is considerable variance between reported results. A comprehensive experiment was therefore designed to investigate the effects of road-surface characteristics on fuel consumption, as a first step toward establishing reliable VOC relations for South African conditions. A passenger car, two medium-sized trucks, and two buses were chosen for coast-down tests to determine rolling resistance over a series of road sections, covering the ranges of surface conditions encountered locally. The models developed predict that at constant speeds on level roads, road-surface characteristics can affect the fuel consumption of passenger cars by up to 7% and that of trucks and buses by up to 20%. It is believed that these models can be applied with confidence in practice, considering the comprehensive nature of the experiment.

Available in PDF, EPUB and Kindle. Book excerpt: This document reports the results of a 3-part field data collection program to determine the sensitivity of user costs to pavement condition factors. Speed data were collected at 15 urban freeway pavement sites and 8 suburban arterial sites. pavement roughness and deterioration were measured at each site. Analyses were conducted to determine relationships between speed change behavior and pavement conditions. Vehicle coast-down and fuel consumption tests were conducted at 11 sites to determine relationships between total vehicle resistance force, speed and pavement conditions. Fuel consumption models wee developed and verified experimentally.

This book was released on 2019 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: The massive use of fuel required by road transportation is accountable for the exploitation of non-renewable energy sources, is a major source of pollutants emission, and implies high economic costs. Rolling resistance is a factor affecting vehicles energy consumption; the structural rolling resistance (SRR) is the component of rolling resistance that occurs due to the deformation of the pavement structure. The present research presents an investigation on the SRR in order to identify its causes, characterize it and develop the instruments to predict its impact on fuel consumption for different road and traffic conditions.First the methods to calculate the SRR on asphalt and concrete pavements were developed. The structural rolling resistance is calculated as the resistance to motion caused by the uphill slope seen by the tires due to the pavement deformation. The SRR can be converted into fuel consumption using the calorific value of the fuel and the engine efficiency, and the greenhouse gas emissions associated with it can be calculated.Purely mechanistic models were used to determine the structural rolling resistance, and the fuel consumption associated with it, on 17 California pavement sections under different loading and environmental conditions. The results were used to develop simple and rapid-to-use mechanistic empirical heuristic models to predict the energy dissipation associated with the structural rolling resistance on any asphalt or concrete pavement.The difference in terms of fuel consumption and pollutants emissions between different pavement structures can be significant and could be included in economic evaluations and life cycle assessment studies. For this purpose, a practical tool was createddeveloped, based on the heuristic models, that allows the calculation of the fuel consumption associated with the SRR for any given traffic and pavement section. Examples of applications of such a tool are presented and discussed.

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.
