where m, k, n, l, and n′ are the number of total cells, the number of empty cells, road traffic density, road length, and the number of lanes, respectively.
The Welsh car developer Riversimple has unveiled its Rasa road-legal engineering prototype of its first two-seater hydrogen fuel cell powered road car, built for full European type approval.
The calculation of the mobile flows between the neighbouring cells is based on total number of handovers in cells (measured or assumed) and information available from the network design stage such as cell coverage, road and subscriber density maps.
For many potential applications of fuel cells, especially road transport, it is highly desirable to use liquid fuels.
Grid cells of road and rail infrastructure were redistributed to match historical statistics on their total length per region, with grid cells reallocated as in case of industry.
In Japan and the United States, Toyota has a total of 18 fuel cell cars undergoing road tests.
Monday, for example, U.P.S. and DaimlerChrysler announced a joint project to put at least one delivery truck powered by a hydrogen fuel cell on the road by 2004.
Down the road, cell phones, personal digital assistants, and smart cards equipped with micropayment technology could even supplement cash in the real world.
Now it's intrusive cell phones and road rage as social analogues of such evil cultural phenomena as women-hating rap lyrics and foul speech on "reality-based" television shows.
In this module, the generation of new vehicles is triggered when the first road cell is empty and its average arrival condition is reflected by the traffic flow data.
