Traffic Jams
Traffic congestion is a condition in transport that is characterized by slower speeds, longer trip times, and increased vehicular Queuing theory, queueing. Traffic congestion on urban road networks has increased substantially since the 1950s, resulting in many of the roads becoming obsolete. When traffic demand is great enough that the interaction between vehicles slows the traffic stream, this results in congestion. While congestion is a possibility for any mode of transportation, this article will focus on automobile congestion on public roads. Mathematically, traffic is modeled as a flow through a fixed point on the route, analogously to fluid dynamics. As demand approaches the capacity of a road (or of the intersections along the road), extreme traffic congestion sets in. When vehicles are fully stopped for periods of time, this is known as a traffic jam or (informally) a traffic snarl-up or a tailback. Drivers can become frustrated and engage in road rage. Drivers and dri ...

Central Business District
A central business district (CBD) is the Commerce, commercial and business center of a city. It contains commercial space and offices, and in larger cities will often be described as a financial district. Geographically, it often coincides with the "city centre" or "downtown". However, these concepts are not necessarily synonymous: many cities have a central ''business'' district located away from its traditional city center, and there may be multiple CBDs within a single urban area. The CBD will often be highly accessible and have a large variety and concentration of specialised goods and services compared to other parts of the city. Midtown Manhattan is the world's largest central business district. In the City of London, the largest concentration of economic output in the world is held there, with many headquarters of major financial and law firms being based in the City. In Chicago, the Chicago Loop is the second-largest central business district in the United States. It is ...

Road Works
Roadworks, also called road construction or road work, occur when part of the road, or in rare cases, the entire road, has to be occupied for work relating to the road, most often in the case of road surface repairs. In the United States road work could also mean any work conducted in close proximity of travel way ( thoroughfare) such as utility work or work on power lines (i.e. telephone poles). The general term of road work is known as work zone. Roadworks can, however, also happen when a major accident occurs and road debris from the crash needs to be cleared. Roadworks are often signposted, although it is possible that the signage comes too late or too sudden or is missing. Typical road work traffic controls are temporary signs, traffic cones, barrier boards and t-top bollards as well as other forms of warning devices. There are standards of temporary traffic control established in each country for various type of road work. Usually, roadworks takes place at night, b ...

Car Accident
A traffic collision, also known as a motor vehicle collision, or car crash, occurs when a vehicle collides with another vehicle, pedestrian, animal, road debris, or other moving or stationary obstruction, such as a tree, pole or building. Traffic collisions often result in injury, disability, death, and property damage as well as financial costs to both society and the individuals involved. Road transport is statistically the most dangerous situation people deal with on a daily basis, but casualty figures from such incidents attract less media attention than other, less frequent types of tragedy. The commonly used term car accident is increasingly falling out of favor with many government departments and organizations: the Associated Press style guide recommends caution before using the term and the National Union of Journalists advises against it in their Road Collision Reporting Guidelines. Some collisions are intentional vehicle-ramming attacks, staged crashes, vehic ...

Road Pricing
Road pricing are user charge, direct charges levied for the use of roads, including Toll road, road tolls, distance or time-based fees, congestion pricing, congestion charges and charges designed to discourage the use of certain classes of vehicle, fuel sources or more polluting vehicles. These charges may be used primarily for revenue generation, usually for road infrastructure financing, or as a transportation demand management tool to reduce peak hour travel behavior, private vehicle travel and the associated traffic congestion or other social and environmental Externality, negative externalities associated with road travel such as tailpipe emissions, air pollution, greenhouse gas emissions, visual intrusion, noise pollution and road traffic collisions. ''Executive Summary, pp. v''. In most countries toll roads, toll bridges and toll tunnels are often used primarily for revenue generation to repay long-term debt issued to finance the toll facility, or to finance capacity ex ...

Private Highway
A private highway is a highway owned and operated for profit by private industry. Private highways are common in Asia and Europe; in addition, a few have been built in the United States on an experimental basis. Typically, private highways are built by companies that charge tolls for a period while the debt is retired, after which the highway is turned over to government control. This allows governments to fulfill immediate transportation needs despite their own budget constraints, while still retaining public ownership of the roads in the long term. An obstacle to private highways is that government regulation can stifle price flexibility and introduce negotiation and paperwork requirements that increase operational expenses, while having to compete against free public roads. In addition, private highways lack some advantages that governments have, such as sovereign immunity against liability for accidents, the use of eminent domain power to acquire private property for roads an ...

Opportunity Cost
In microeconomic theory, the opportunity cost of a choice is the value of the best alternative forgone where, given limited resources, a choice needs to be made between several mutually exclusive alternatives. Assuming the best choice is made, it is the "cost" incurred by not enjoying the ''benefit'' that would have been had if the second best available choice had been taken instead. The '' New Oxford American Dictionary'' defines it as "the loss of potential gain from other alternatives when one alternative is chosen". As a representation of the relationship between scarcity and choice, the objective of opportunity cost is to ensure efficient use of scarce resources. It incorporates all associated costs of a decision, both explicit and implicit. Thus, opportunity costs are not restricted to monetary or financial costs: the real cost of output forgone, lost time, pleasure, or any other benefit that provides utility should also be considered an opportunity cost.

Tragedy Of The Commons
The tragedy of the commons is the concept that, if many people enjoy unfettered access to a finite, valuable resource, such as a pasture, they will tend to overuse it and may end up destroying its value altogether. Even if some users exercised voluntary restraint, the other users would merely replace them, the predictable result being a "tragedy" for all. The concept has been widely discussed, and criticised, in economics, ecology and other sciences. The metaphorical term is the title of a 1968 essay by ecologist Garrett Hardin. The concept itself did not originate with Hardin but rather extends back to classical antiquity, being discussed by Aristotle. The principal concern of Hardin's essay was overpopulation of the planet. To prevent the inevitable tragedy (he argued) it was necessary to reject the principle (supposedly enshrined in the Universal Declaration of Human Rights) according to which every family has a right to choose the number of its offspring, and to replace it b ...
