The impacts of climate change have prompted governments to pledge introduce policies aiming limit the increasing temperature. One strategies involves reducing and, eventually, eliminating internal combustion engines in favour electric vehicles. This strategy has been implemented by many transportation services, and FREE NOW pledged be carbon neutral 2030. study analyses taxi fleet composition D...

FOR MOST LAW ENFORCEMENT AND EMERGENCY SERVICES AGENCIES, THE costs related to the purchasing, equipping, operating and maintaining of fleets is the largest single recurring cost, outside that of personnel. The cost of acquiring vehicles, the costs associated with equipping and maintaining these vehicles, and escalating fuel costs have created difficulties for many departments— including police...

the first international convention on maritime transportation is thebrussels’ convention of 1924. this convention was widely acceptedthroughout the world and; thus, lasted for a long time due to the widespreadsupport of the countries possessing fleet for this convention and the lack ofexistence of a legal document in terms of maritime transportation. thepassage of time together with innovations...

One significant obstacle to meeting aggressive federal and state alternative fuel consumption targets is the relative scarcity of retail fueling stations that carry alternative fuels. Policies that encourage or mandate use of alternative fuel vehicles in government fleets, thereby increasing demand for such fuels, are one popular approach to stimulating further development of the alternative fu...

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 ...

The impact of a potential future fleet of supersonic aircraft on contrail coverage and contrail radiative forcing is investigated by means of simulations with the general circulation model ECHAM4.L39(DLR) including a contrail parameterization. The model simulations consider air traffic inventories of a subsonic fleet and of a combined fleet of suband supersonic aircraft for the years 2025 and 2...

This paper describes a tabu search heuristic for a vehicle routing problem where the owner of a private fleet can either visit a customer with one of his vehicles or assign the customer to a common carrier. The owner's objective is to minimize the variable and fixed costs for operating his fleet plus the total costs charged by the common carrier. The proposed tabu search is shown to outperform ...

To the Editor: Ezri et al.1 described serum electrolyte changes following ingestion of cathartics prior to bowel resection surgery. The authors dosed 90 mL of Fleet® Phospho-soda® to their subjects. This is twice the recommended dose of 30–45 mL according to the current professional Fleet® Phospho-soda® labelling.2 Fleet® Phospho-soda® should be used only at the recommended dosage and only in p...

The Indiana Department of Transportation (INDOT) spends approximately $30 to $60 million a year on deicing salt and operates fleet 1,000 winter operations trucks distributed among 140 locations. entire is now instrumented with location telematics, all new have integrated dash cameras, spreader application rate plow up/plow down into the telematics link. When storms occur, they varying regional ...
