Download or read book Vehicle Operating Costs Related to Operating Mode Road Design and Pavement Condition written by BC. Butler and published by . This book was released on 1985 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: From 1979 through 1982 the Federal Highway Administration contracted with the Texas Research and Development Foundation to update vehicle operating cost tables. In this research five components of vehicle operating cost were studied, including fuel consumption, maintenance and repair, oil consumption, tire consumption, and depreciation. The approach used in this research was to identify the consumption involved for each of these parameters and then to price these components to obtain vehicle operating costs. This approach allows future updating of the vehicle operating cost tables from simply knowing the changes in prices. This is highly desirable since component consumption changes much less frequently than the unit prices. The results of this research present a new set of table relating vehicle operating costs to the serviceability index of pavements and the geometric design features of the roads. The component consumption tables were established for constant speed and speed change cycle operations.

This book was released on 1999 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis report will be of interest to transportation agency planners; design, construction, and maintenance engineers; and administrators, managers, economists, and other decisionmakers involved in programming highway pavement projects. This synthesis describes current practice with regard to road user and mitigation costs in highway pavement projects. Information for the synthesis was collected by surveying U.S. and Canadian transportation agencies and by conducting a literature search of both domestic and foreign publications. This report of the Transportation Research Board provides detailed information on the various methods employed by transportation agencies to estimate user costs. The advantages and disadvantages of each are reported. Information on the various components of user costs (that is, time related, vehicle operating, safety, and environmental costs) is also included. In addition, the study reports on the various mitigation strategies available to agencies to reduce user costs. Information is also provided on how user costs and mitigation strategies have been applied to evaluate different alternatives; and how uncertainties, political considerations, and quality control contribute to the decisionmaking process.

Download or read book Effect of Pavement Type on Fuel Consumption in City Driving written by Palinee Sumitsawan and published by . This book was released on 2011 with total page pages. 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.

Book excerpt: The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

Available in PDF, EPUB and Kindle. Book excerpt: Road-user costs are the largest cost elements in road transport. Improvements in road conditions can yet pay substantial dividends by reducing vehicle operating costs. Expressing vehicle operating costs in relation to road characteristics--geometry and pavement condition--is the logical approach. For certain cost components, especially fuel consumption, the required data can be obtained by controlled experiments. Vehicle maintenance costs utilizing extensive road-user surveys are needed. This volume takes an aggregate-mechanistic view of vehicle speed and operating costs under free flow conditions. Basing their analysis on the mechanistic principles of propulsion and motion as well as on postulated assumptions of driver behavior, the authors arrive at predictions at three levels of detail, ranging from a simulation method for use in detailed geometric design at the link level to an aggregate method for use in investment planning at the sectoral level. The models were estimated using the comprehensive database collected in the Brazil-UNDP-World Bank highway research project and were validated along with data sets from India. One of the significant contributions to highway economics research made in this study is the probabilistic limiting velocity approach to steady-state speed prediction, which, combined with the aggregate-mechanistic methodology, will provide a possible basis for future research on the far more complex problem of operating costs under congested conditions.

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.
