Advances in vehicle design and fuel quality mean cars can be made cleaner and more efficient. Lower emissions of carbon monoxide (CO), nitrogen oxides (NOx), sulphur dioxide (SO2), particles (including the fine dust and soot PM10) and hydrocarbons (HCs) also known as volatile organic compounds (VOCs) will lead to better urban air quality and less summertime smog. Lower emissions of carbon dioxi...

This paper derives the distribution of the deviation distance to visit an alternative fuel station. Distance is measured as the Euclidean distance on a continuous plane. The distribution explicitly considers the vehicle range and whether the round trip between origin and destination can be made. Three cases are examined: fuel is available at both origin and destination, fuel is available at eit...

Liquefied natural gas (LNG) is being developed as a heavy vehicle fuel. The reason for developing LNG is to reduce our dependency on imported oil by eliminating technical and costs barriers associated with its usage. The U.S. Department of Energy (DOE) has a program, currently in its third year, to develop and advance costeffective technologies for operating and refueling natural gas–fueled hea...

INTRODUCTION The fuel tax system used for financing the U.S. highway transportation infrastructure is becoming less effective and less equitable over time. While many people prefer the relatively less fuel-efficient sport utility vehicles, the general trend over time is toward more fuel efficiency. While the popularity of light trucks and SUVs has slowed the increase in average fuel economy for...

The culmination of new vehicle technology, greater competition in energy markets, and government policies to reduce pollution and energy consumption will result in changes to the personal vehicle marketplace. To measure future vehicle preferences, stated preference surveys have been the dominant approach. Prior research has been limited to a narrow focus of accelerating respondents to a hypothe...

--The global fuel crisis in the recent times has generated awareness amongst many countries of their vulnerability to oil embargoes and shortages. Considerable attention has been focused on the development of alternative fuel sources. The Motor vehicle population has also increased tremendously over the last decade in India. Environmental degradation is another outcome of growth in motor vehicl...

The future of U.S. transport energy requirements and emissions is uncertain. Transport policy research has explored a number of scenarios to better understand the future characteristics of U.S. light-duty vehicles. Deterministic scenario analysis is, however, unable to identify the impact of uncertainty on the future U.S. vehicle fleet emissions and energy use. Variables determining the future ...

The future of US transport energy requirements and emissions is uncertain. Transport policy research has explored a number of scenarios to better understand the future characteristics of US light-duty vehicles. Deterministic scenario analysis is, however, unable to identify the impact of uncertainty on the future US vehicle fleet emissions and energy use. Variables determining the future fleet ...

A fuel-supply system using movable fuel-supply vehicles (FSVs) is proposed and its performance is evaluated. Both FSVs and vehicles requesting fuel are equipped with networked sensors. The sensors in FSVs are location sensors, and those in vehicles requesting fuel are for determining the remaining amount of fuel and the location of the vehicle. The time from when a fuel request is generated unt...

Two major emerging automotive technologies are the continued development of hybrid-electric drivetrains and telematics-enabled (or ‘intelligent’) vehicles capable of garnering and utilizing information about the traffic environment in which the vehicles are operating. The significant costs of each of these technologies are located internal to the vehicle (i.e. the powertrain) in the former case...
