Disappearing Traffic
In economics, induced demand – related to latent demand and generated demandSchneider, Benjamin (September 6, 2018"CityLab University: Induced Demand"''CityLab'' – is the phenomenon whereby an increase in supply results in a decline in price and an increase in consumption. In other words, as a good or service becomes more readily available and mass produced, its price goes down and consumers are more likely to buy it, meaning that demand subsequently increases. This is consistent with the economic theory of supply and demand. In transportation planning, induced demand, also called "induced traffic" or consumption of road capacity, has become important in the debate over the expansion of transportation systems, and is often used as an argument against increasing roadway traffic capacity as a cure for congestion. Induced traffic may be a contributing factor to urban sprawl. City planner Jeff Speck has called induced demand "the great intellectual black hole in city pla ...

Traffic Congestion
Traffic congestion is a condition in transport that is characterized by slower speeds, longer trip times, and increased vehicular queueing. Traffic congestion on urban road networks has increased substantially since the 1950s. When traffic demand is great enough that the interaction between vehicles slows the speed of the traffic stream, this results in some congestion. While congestion is a possibility for any mode of transportation, this article will focus on automobile congestion on public roads. 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. Traffic congestion can lead to drivers becoming frustrated and engaging in road rage. Mathematically, traffic is modeled as a flow through a fixed point on the route, analogously to fluid dynamics. Causes Traffic congestion occurs when ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern California Association Of Governments
The Southern California Association of Governments (SCAG) is the Metropolitan Planning Organization (MPO) of six of the ten counties in Southern California, serving Imperial County, Los Angeles County, Orange County, Riverside County, San Bernardino County, and Ventura County. San Diego County's MPO is the San Diego Association of Governments, which is an unrelated agency. SCAG is the largest MPO in the United States, representing over 18.5 million people in an area covering over . As the designated MPO, SCAG is mandated by the federal government to research and draw up plans for transportation, growth management, hazardous waste management, and air quality. Additional mandates exist at the state level Governance SCAG's policy direction is guided by the 86-member official governing board known as the Regional Council. The Regional Council is composed of 67 Districts that include an elected representative of one or more cities of approximately equal population levels that ...

County Surveyor
A county surveyor is a public official in the United Kingdom and the United States. United Kingdom Webb & Webb describe the increasing chaos that began to prevail within this same period in field of county surveying in England and Wales, with county surveyors appointed by the justices of the peace at quarter sessions. Eventually, the military defence component of county surveying in the UK began to separate from the civil in 1791, with the Crown's 'Board of Ordnance' being commissioned to carry out a comprehensive survey of the South Coast of England which, as a result of 'the last invasion of Britain 1797', at Fishguard in South West Wales ultimately extended to all of the UK. With that shift in emphasis, county surveying began to concentrate more on its civil engineering and civic architecture roles, producing the historically famous British county surveyors such as Thomas Telford, John Loudon McAdam and John Nash; the expression, "county surveyor", became a UK statutory tit ...

Verrazano Narrows Bridge
The Verrazzano-Narrows Bridge ( ) is a suspension bridge connecting the New York City boroughs of Staten Island and Brooklyn. It spans the Narrows, a body of water linking the relatively enclosed New York Harbor with Lower New York Bay and the Atlantic Ocean. It is the only fixed crossing of the Narrows. The double-deck bridge carries 13 lanes of Interstate 278: seven on the upper level and six on the lower level. The span is named for Giovanni da Verrazzano, who in 1524 was the first European explorer to enter New York Harbor and the Hudson River. Engineer David B. Steinman proposed a bridge across the Narrows in the late 1920s, but plans were deferred over the next twenty years. A 1920s attempt to build a Staten Island Tunnel was aborted, as was a 1930s plan for vehicular tubes underneath the Narrows. Discussion of a tunnel resurfaced in the mid-1930s and early 1940s, but the plans were again denied. In the late 1940s, urban planner Robert Moses championed a bridge across th ...

Throgs Neck Bridge
The Throgs Neck Bridge is a suspension bridge in New York City, carrying six lanes of Interstate 295 (New York), Interstate 295 (I-295) over the East River where it meets the Long Island Sound. The bridge connects the Throggs Neck section of the Bronx with the Bay Terrace, Queens, Bay Terrace section of Queens. Opened on January 11, 1961, it is the newest bridge across the East River and was built to relieve traffic on the Bronx–Whitestone Bridge, to the west. The Throgs Neck Bridge is also the easternmost crossing of the East River. Due to this and its proximity to Interstate 95 in New York, I-95, it is the closest route from Long Island to New Jersey via the George Washington Bridge, as well as points north. The Throgs Neck Bridge is owned by the government of New York City and operated by the Triborough Bridge and Tunnel Authority (TBTA), an affiliate agency of the Metropolitan Transportation Authority (MTA).

East River
The East River is a saltwater tidal estuary in New York City. The waterway, which is actually not a river despite its name, connects Upper New York Bay on its south end to Long Island Sound on its north end. It separates the borough of Queens on Long Island from the Bronx on the North American mainland, and also divides Manhattan from Queens and Brooklyn, also on Long Island.Hodges, Godfrey. "East RIver" in Jackson, pp.393–93 Because of its connection to Long Island Sound, it was once also known as the ''Sound River''. The tidal strait changes its direction of flow frequently, and is subject to strong fluctuations in its current, which are accentuated by its narrowness and variety of depths. The waterway is navigable for its entire length of , and was historically the center of maritime activities in the city. Formation and description Technically a drowned valley, like the other waterways around New York City, the strait was formed approximately 11,000 years ago at the e ...
