In this thesis we examine how fuel price variation affects the optimal mix of services in intercity transportation. Towards this end, we make two main contributions. The first is the development of an analytic total logistics cost model of intercity transportation, which is sensitive to fuel price and incorporates multiple classes of vehicles serving passengers with differentiated values of tim...

The impact on the usage of commercial fuels such as gasoline in automobile vehicles is an alarm in terms of health effects as it emits higher level of carbon dioxide to the atmosphere. In addition, the need and demand for Gasoline products are in the increasing trend because of more number of vehicles which are on road and Governments plan to increase the cost of fuel. As slowly the scarcity of...

NOTICE This Technical Report does not necessarily represent final EPA decisions or positions. It is intended to present technical analysis of issues using data that are currently available. The purpose in the release of such reports is to facilitate an exchange of technical information and to inform the public of technical developments. Executive Summary This study proposes a modeling methodolo...

In this two-part paper, a topological analysis of powertrains for refuse-collecting vehicles (RCVs) based on simulation of different architectures (internal combustion engine, hybrid electric, and hybrid hydraulic) on real routes is proposed. In this second part, three different hybrid electric powertrain architectures are proposed and modeled. These architectures are based on the use of fuel c...

The Fuel Quality Standards Act 2000, which received Royal Assent on 21 December 2000, provides the framework for a national fuel quality standards regime. This legislation has been developed in response to an urgent need to address the quality of fuel currently available in Australia. New vehicle emission standards, harmonising Australian standards with international vehicle emission standards,...

This Paper proposed the estimation method of fuel consumption from vehicle information through OBD-II. We assumed RPM, TPS had a relationship with fuel consumption. We got the output as fuel-consumption from a vehicle RPM, TPS as input by using polynomial equations. We had modeling as quadric function and surface function with OBD-II data and fuel consumption data supported by automotive compan...

Beijing, the capital of China, has experienced rapid motorization since 1990; a trend that is likely to continue. The growth in vehicles and the corresponding emissions create challenges to improving the urban air quality. In an effort to reduce the impact of vehicle emissions on urban air quality, Beijing has adopted a number of vehicle emission control strategies and policies since the mid 19...
