	Transportation Problem
		This problem is an example of a transportation problem.
		Transportation problems are often used in, surprise, transportation planning.
		In general, the transportation model is concerned with distributing (literally or figuratively) a commodity from a group of supply centers, called sources to a group of receiving centers, called destinations to minimize total cost.

	HKUST Institutional Repository: Item 1783.1/1492
		From the mathematical viewpoints, the bilevel transportation problem with the network equilibrium constraint can be characterized by the bilevel programming model in which the lower level problem is a nonlinear programming problem that represents the network equilibrium problem.
		Therefore, it is a significant and challenging issue to study the relevant models and algorithms for the bilevel transportation problem by exploring its inherent nature.
		For the combined land-use and transportation model for work trips problem, a new bilevel programming model is established to find the maximum work trip generation and the corresponding heuristic algorithm is proposed.

	Linear Optimization
		The problem may be one of reducing the cost of operation while maintaining an acceptable level of service, and profit of current operations, or providing a higher level of service without increasing cost, maintaining a profitable operation while meeting imposed government regulations, or "improving" one aspect of product quality without reducing quality in another.
		Optimization problems are often classified as linear or nonlinear, depending on whether the relationship in the problem is linear with respect to the variables.
		However, for minimization problems the opposite is true, that is, you are moving the iso-value objective parallel to itself closer to the origin point, while having at least a common point with the feasible region.

	Transportation Needs of Oklahomans with Disabilities Survey Report 2002 (Site not responding. Last check: 2007-10-31)
		Among those who said transportation was a major problem, the most frequent concerns were lack of intercity transportation, insufficient public transportation or none at all in their locale, lack of sidewalks, limited or no door-to-door transportation and inaccessible streets, walkways and intersections.
		Transportation dependent households: Two thirds (65.5%) of respondents or 2,526 individuals reported there are persons in their households, age 16 or older, who are dependent on public transportation or rides from friends or relatives because they do not drive or do not have a car.
		Lack of intercity transportation was also a prime concern for respondents who indicated problems getting to stores, restaurants and events and those who said they need better transportation in order to live independently in their communities.

		The transportation of MSW to the nation's landfills is the symptom.
		The regulation of transportation of radioactive materials is governed at the Federal level primarily by three agencies: the Department of Transportation, (DOT), the Nuclear Regulatory Commission, (NRC), and the U.S. Department of Energy, (DOE).
		Again, the transportation of municipal solid waste, hazardous waste and low-level radioactive waste is not the problem.

	Portland Transport: Urgency of Transportation Funding Problem
		In refering to transportation investment Ross said: "The fact is that other public investment is far more important to the economy of Portland then transportation." Yes Ross, education but when it comes to brick and mortar there is nothing else that compares to transportation.
		The problem is that you have to provide opportunities for people who want to use transit to live in Clark County including other transit and walkable neighborhoods with local services.
		But the point is it is not the costs of transportation that ought to drive this discussion, its what kind of community is being created and how attractive it is. A good transporation system is part of that, but not the most important part.

	Brookline Transportation Board Main
		The Brookline Transportation Board was formed in 1974 by an act of the State Legislature to administer all matters relating to parking and transportation in the Town.
		The six members of the Transportation Board must be Brookline residents and are appointed by the Board of Selectmen to staggered three-year terms.
		In addition to these duties, the Transportation Board takes a proactive role in addressing transportation problems that affect both neighborhoods and the Town as a whole, while also recommending necessary capital projects.

	joshp's progress on fix seattle's transportation problem on 43 Things
		Like many problems, when I focused on it for a bit, I found I didn’t really think it was that bad of a problem.
		Land use laws in suburbs effectively protect against city “problems” (like density, multi-family housing, crowded schools, mass transit), but the suburbs remain close enough to the urban core to get access to jobs, culture, and human conviviality.
		The transportation system we build within Seattle should be a monument to our city’s character and ambitions, not another way to allow suburbs to siphon the dynamism of Seattle.

	fix seattle's transportation problem on 43 Things
		My other main point is: a monorail would be more a city development rather than a solution to a transportation problem.
		The real “problem” is the lack of options to getting stuck in traffic at certain times, but to be honest, living and working in Seattle, I rarely have a real problem with traffic.
		The problem is still there, and I would argue that we need a solution now more than ever.

	AMCA: Multi-Index Time Minimizing Transportation Problem by Archana Khurana
		Both these algorithms involve a finite number of iterations and are based on the concept of moving from one basic feasible solution to another basic feasible solution until it is not further possible to reduce the time.
		So either of the two algorithms can be applied to solve a multi-index time transportation problem.
		Also the problem discussed by them is two dimensional while in this paper we have considered a three dimensional problem which can be extended to a multi-index time transportation problems.

		Its performance is even better for degenerate problems in which the weights take only a small number of integer values.
