60-419: Streets is the plural of street , a type of road. Streets or The Streets may also refer to: Street Originally, the word street simply meant a paved road ( Latin : via strata ). The word street is still sometimes used informally as a synonym for road , for example in connection with the ancient Watling Street , but city residents and urban planners draw a crucial modern distinction:

120-399: A New York Times writer lets casually slip the observation that automobile-laden Houston Street , in lower Manhattan , is "a street that can hardly be called 'street' anymore, transformed years ago into an eight-lane raceway that alternately resembles a Nascar event and a parking lot." Published in the paper's Metro section, the article evidently presumes an audience with an innate grasp of

180-432: A housing development feeding directly into individual driveways . In the last half of the 20th century planners of suburban streets often abandoned the tradition of a rigid, rectangular grid , and instead designed systems to discourage through-traffic. This and other traffic calming methods provided quiet for families and play space for children within a streetscape . Adolescent suburbanites find, in attenuated form,

240-406: A sewage treatment plant or disposal. Sanitary sewers are a type of gravity sewer and are part of an overall system called a "sewage system" or sewerage . Sanitary sewers serving industrial areas may also carry industrial wastewater . In municipalities served by sanitary sewers, separate storm drains may convey surface runoff directly to surface waters. An advantage of sanitary sewer systems

300-824: A charter member of the Greenwood Garden Club. In 1950, Gwin received a citation from the National Congress of the Daughters of the American Revolution in recognition of her work in the conservation of trees. Streets also tend to aggregate establishments of similar nature and character. East 9th Street in Manhattan , for example, offers a cluster of Japanese restaurants, clothing stores, and cultural venues. In Washington, D.C., 17th Street and P Street are well known as epicenters of

360-538: A city is essential to its commerce and vitality, and streets provide the physical space for this activity. In the interest of order and efficiency, an effort may be made to segregate different types of traffic. This is usually done by carving a road through the middle for motorists, reserving pavements on either side for pedestrians; other arrangements allow for streetcars , trolleys , and even wastewater and rainfall runoff ditches (common in Japan and India ). In

420-545: A city. For example, Yonge Street divides Toronto into east and west sides, and East Capitol Street divides Washington, D.C. into north and south. Some streets are associated with the beautification of a town or city. Greenwood, Mississippi 's Grand Boulevard was once named one of America's ten most beautiful streets by the U.S. Chambers of Commerce and the Garden Clubs of America. The 1,000 oak trees lining Grand Boulevard were planted in 1916 by Sally Humphreys Gwin,

480-560: A combination of tram lanes or separate alignments are used, sometimes on a segregated right of way . Signalling and effective braking reduce the risk of a tram accident . Often, a curb ( British English : Kerb ) is used to separate the vehicle traffic lanes from the adjacent pavement area and where people on bicycles are considered properly are used to separate cycling from traffic as well. Street signs , parking meters , bicycle stands , benches , traffic signals , and street lights are often found adjacent to streets. They may be behind

540-614: A few hours or a day, in order to make it possible for the inhabitants to use their street for recreational activities. Cities implementing this initiative include Kolkata Madurai , Visakhapatnam and Bangalore . In the United States, "open street" events have been arranged in Detroit and New York City . Sanitary sewer A sanitary sewer is an underground pipe or tunnel system for transporting sewage from houses and commercial buildings (but not stormwater ) to

600-520: A main street, these lanes may be separated by intermittent lane lines , marked on the street pavement. Side streets often do not have centre lines or lane lines. Many streets, especially side streets in residential areas, have an extra lane's width on one or both sides for parallel parking . Most minor side streets allowing free parallel parking do not have pavement markings designating the parking lane. Main streets more often have parking lanes marked. Some streets are too busy or narrow for parking on

660-446: A relatively high level of activity. Commerce and public interaction are more visible on main streets, and vehicles may use them for longer-distance travel. Side streets are quieter, often residential in use and character, and may be used for vehicular parking. Circulation, or less broadly, transportation , is perhaps a street's most visible use, and certainly among the most important. The unrestricted movement of people and goods within

720-495: A road's main function is transportation, while streets facilitate public interaction. Examples of streets include pedestrian streets , alleys , and city-centre streets too crowded for road vehicles to pass. Conversely, highways and motorways are types of roads, but few would refer to them as streets. The word street has its origins in the Latin strata (meaning "paved road" – an abbreviation from via strata ); it

780-598: A social function, allowing neighbors to meet and interact on their walks. They also can foster economic activity, such as window shopping and sidewalk cafes . Some studies have found that shops on streets with sidewalks get more customers than similar shops without sidewalks. An important element of sidewalk design is accessibility for persons with disabilities. Features that make sidewalks more accessible include curb ramps , tactile paving and accessible traffic signals. The Americans with Disabilities Act requires accessibility improvement on new and reconstructed streets within

840-530: A street, despite its name, and locals are more apt to refer to the "street" outside than the "road". A desolate road in rural Montana , on the other hand, may bear a sign proclaiming it "Davidson Street", but this does not make it a "street" except in the original sense of a paved road. In the United Kingdom the inhabitants of many towns will refer to their main thoroughfare as the High Street (in

900-427: A street, is often paved and used for travel . However, a street is characterized by the degree and quality of the street life which it facilitates, whereas a road serves primarily as a through-passage for road vehicles or (less frequently) for pedestrians . Buskers , beggars , boulevardiers , patrons of pavement cafés , peoplewatchers , streetwalkers , and a diversity of other characters are habitual users of

960-408: A street; the same people would not typically be found on a road. A stroad is a thoroughfare that mixes - often unhappily - the characteristics of a street and a road. In rural and suburban environments where street life is rarer, people frequently use the terms "street" and "road" interchangeably. Still, even here, what is called a "street" is usually a smaller thoroughfare, such as a road within

1020-505: A treatment plant. Force mains are typically constructed of welded steel or HDPE jointed to resist pressures within the pipe. Force mains are substantially different from pressure sewers which serve individual properties or groups of properties and provide a means of injecting sewage into a local gravity main. Effluent sewer systems, also called septic tank effluent drainage (STED) or solids-free sewer (SFS) systems, have septic tanks that collect sewage from residences and businesses, and

1080-418: Is a pumped sewer that may be necessary where gravity sewers serve areas at lower elevations than the sewage treatment plant, or distant areas at similar elevations. A lift station is a sewer sump that lifts accumulated sewage to a higher elevation. They may also be used to prime an inverted siphon used to cross underneath rivers or other obstructions. The pump may discharge to another gravity sewer or directly to

1140-607: Is complicated by making provisions to receive lateral flows without accepting undesirable infiltration from inadequately sealed junctions. Some sewers have tall vent pipes to release foul gases well up away from people. Common names for these pipes are stink pipe, stink pole, stench pipe and sewer ventilation pipe. Sanitary sewers evolved from combined sewers built where water was plentiful. Animal feces accumulated on city streets while animal-powered transport moved people and goods. Accumulations of animal feces encouraged dumping chamber pots into streets where night soil collection

1200-481: Is required to prevent inappropriate connection of cellar, yard, and roof drains to sanitary sewers. The probability of inappropriate connections is higher where combined sewers and sanitary sewers are found in close proximity, because construction personnel may not recognize the difference. Many older cities still use combined sewers while adjacent suburbs were built with separate sanitary sewers. For decades, when sanitary sewer pipes cracked or experienced other damage,

1260-506: Is that they avoid combined sewer overflows . Sanitary sewers are typically much smaller in diameter than combined sewers which also transport urban runoff . Backups of raw sewage can occur if excessive stormwater inflow or groundwater infiltration occurs due to leaking joints, defective pipes etc. in aging infrastructure. Sewage treatment is less effective when sanitary waste is diluted with stormwater, and combined sewer overflows occur when runoff from heavy rainfall or snowmelt exceeds

1320-493: Is thus related to stratum and stratification . The first recorded use of word stratæ referring to the road has been made by Eutropius . Ancient Greek stratos means army: Greeks originally built roads to move their armies. Old English applied the word to Roman roads in Britain such as Ermine Street , Watling Street , etc. Later it acquired a dialectical meaning of "straggling village", which were often laid out on

1380-670: The United States and Canada it would be called the Main Street —however, occasionally "Main Street" in a city or town is a street other than the de facto main thoroughfare), and many of the ways leading off it will be named "Road" despite the urban setting. Thus the town's so-called "Roads" will actually be more like streets than like road. Some streets may even be called "highways", even though they may carry no highway designation at all: This may arise when an historic road that

1440-471: The Ōtemachi subway station, the elevated pedestrian skyway networks of Minneapolis and Calgary , the underground cities of Atlanta and Montreal , and the multilevel streets in Chicago . Transportation is often misunderstood to be the defining characteristic, or even the sole purpose, of a street. This has not been the case since the word "street" came to be limited to urban situations, and even in

1500-462: The "destination" districts, when the volume of activity outgrows the capacity of private passenger vehicles to support it. A feature universal to all streets is a human-scale design that gives its users the space and security to feel engaged in their surroundings, whatever through traffic may pass. Despite this, the operator of a motor vehicle may (incompletely) regard a street as merely a thoroughfare for vehicular travel or parking . As far as concerns

1560-587: The US. In most jurisdictions, bicycles are legally allowed to use streets, and required to follow the same traffic laws as motor vehicle traffic. Where the volume of bicycle traffic warrants and available right-of-way allows, provisions may be made to separate cyclists from motor vehicle traffic. Wider lanes may be provided next to the curb, or shoulders may be provided. Bicycle lanes may be used on busy streets to provide some separation between bicycle traffic and motor vehicle traffic. The bicycle lane may be placed between

1620-412: The amenities of street life in shopping malls where vehicles are forbidden. A town square or plaza is a little more like a street, but a town square is rarely paved with asphalt and may not make any concessions for through-traffic at all. There is a haphazard relationship, at best, between a thoroughfare's function and its name. For example, London's Abbey Road serves all the vital functions of

1680-400: The automobile age, is still demonstrably false. A street may be temporarily blocked to all through traffic in order to secure the space for other uses, such as a street fair , a flea market , children at play, filming a movie, or construction work. Many streets are bracketed by bollards or Jersey barriers so as to keep out vehicles. These measures are often taken in a city's busiest areas,

1740-544: The center of the city's French Quarter . Similarly, the Bowery has at various times been New York City 's theater district , red-light district , skid row , restaurant supply district, and the center of the nation 's underground punk scene . Madison Avenue and Fleet Street are so strongly identified with their respective most famous types of commerce, that their names are sometimes applied to firms located elsewhere. Other streets mark divisions between neighborhoods of

1800-507: The city's (relatively small) gay culture. Many cities have a Radio Row or Restaurant Row . Like in Philadelphia there is a small street called Jewelers' row giving the identity of a "Diamond district". This phenomenon is the subject of urban location theory in economics . In Cleveland, Ohio , East 4th Street has become restaurant row for Cleveland. On East 4th is Michael Symon 's Lola Bistro and other restaurants. A road , like

1860-427: The developed world, sewers are pipes from buildings to one or more levels of larger underground trunk mains, which transport the sewage to sewage treatment facilities. Vertical pipes, usually made of precast concrete , called manholes , connect the mains to the surface. Depending upon site application and use, these vertical pipes can be cylindrical , eccentric , or concentric . The manholes are used for access to

1920-422: The driver, a street can be one-way or two-way : vehicles on one-way streets may travel in only one direction, while those on two-way streets may travel both ways. One way streets typically have signs reading "ONE WAY" and an arrow showing the direction of allowed travel. Most two-way streets are wide enough for at least two lanes of traffic. Which lane is for which direction of traffic depends on what country

1980-498: The effluent that comes out of the tank is sent to either a centralized sewage treatment plant or a distributed treatment system for further treatment. Most of the solids are removed by the septic tanks, so the treatment plant can be much smaller than a typical plant. In addition, because of the vast reduction in solid waste, a pumping system, rather than a gravity system, can be used to move the wastewater. The pipes have small diameters, typically 1.5 to 4 inches (4 to 10 cm). Because

2040-405: The expected service life of the repair. Another popular method for replacing aged or damaged lines is called pipe bursting , where a new pipe, typically PVC or ABS plastic, is drawn through the old pipe behind an "expander head" that breaks apart the old pipe as the new one is drawn through behind it. These methods are most suitable for trunk sewers, since repair of lines with lateral connections

2100-590: The hydraulic capacity of sewage treatment plants . To overcome these disadvantages, some cities built separate sanitary sewers to collect only municipal wastewater and exclude stormwater runoff, which is collected in separate storm drains. The decision to build a combined sewer system or two separate systems is mainly based on the need for sewage treatment and the cost of providing treatment during heavy rain events. Many cities with combined sewer systems built their systems prior to installing sewage treatment plants, and have not subsequently replaced those sewer systems. In

2160-572: The investment cost for simplified sanitary sewers can be about half the cost of conventional sewers, the requirements for operation and maintenance are usually higher. Simplified sewers are most common in Brazil and other developing countries. In low-lying communities, wastewater is often conveyed by vacuum sewer . Pipelines range in size from pipes of 125 millimetres (4.9 in) in diameter up to 280 millimetres (11 in) in diameter. Vacuum sewer systems use differential atmospheric pressure to move

2220-431: The liquid to a central vacuum station. Sanitary sewer overflow can occur due to blocked or broken sewer lines, infiltration of excessive stormwater or malfunction of pumps. In these cases untreated sewage is discharged from a sanitary sewer into the environment prior to reaching sewage treatment facilities. To avoid such overflows, maintenance is required. Blockage prevention campaigns or regulations (e.g. requiring

2280-524: The main shopping precinct is located around Queen Street and Karangahape Road . Streets have existed for as long as humans have lived in permanent settlements (see civilization ). However, the development of modern civilization in much of the New World was driven by transportation provided by motor vehicles. In some parts of the English-speaking world, such as North America, many think of

2340-526: The majority elsewhere (though not in Japan; see Japanese addressing system ) are given a street or road name , or at least a number, to identify them and any addresses located along the streets. Alleys , in some places, do not have names. The length of a lot of land along a street is referred to as the frontage of the lot. A street may assume the role of a town square for its regulars. Jane Jacobs , an economist and prominent urbanist, wrote extensively on

2400-585: The mid-20th century, as the automobile threatened to overwhelm city streets with pollution and ghastly accidents, many urban theorists came to see this segregation as not only helpful but necessary in order to maintain mobility. Le Corbusier , for one, perceived an ever-stricter segregation of traffic as an essential affirmation of social order—a desirable, and ultimately inevitable, expression of modernity. To this end, proposals were advanced to build "vertical streets" where road vehicles, pedestrians, and trains would each occupy their own levels. Such an arrangement, it

2460-665: The modern urban role of the street. To the readers of the Metro section, vehicular traffic does not reinforce, but rather detracts from, the essential "street-ness" of a street. At least one map has been made to illustrate the geography of naming conventions for thoroughfares - comparing and contrasting "avenue", "boulevard", "circle", "road", "street", and other labels. Streets may be used as cultural spaces, for socializing and street parties , or for public festivals. In India, some cities have designated one or more streets as "happy street" or "fun street", closing them for motor traffic for

2520-410: The only option was an expensive excavation, removal and replacement of the damaged pipe, typically requiring street repavement afterwards. In the mid-1950s a unit was invented where two units at each end with a special cement mixture in between was pulled from one manhole cover to the next, coating the pipe with the cement under high pressure, which then cured rapidly , sealing all cracks and breaks in

2580-425: The pavement may designate the meter corresponding to a parking space. Some wide streets with light traffic allow angle parking or herringbone parking . Sidewalks (US usage) or pavements (UK usage) are often located alongside on one or usually both sides of the street within the public land strips beyond the curbs. Sidewalks serve a traffic purpose, by making walking easier and more attractive, but they also serve

2640-445: The pipe. Today, a similar method using epoxy resin is used by some municipalities to re-line aging or damaged pipes, effectively creating a "pipe in a pipe". These methods may be unsuitable for locations where the full diameter of the original pipe is required to carry expected flows, and may be an unwise investment if greater wastewater flows may be anticipated from population growth, increased water use, or new service connections within

2700-601: The population to be served over the anticipated life of the sewer, per capita wastewater production, and flow peaking from timing of daily routines. Minimum sewer diameters are often specified to prevent blockage by solid materials flushed down toilets; gradients may be selected to maintain flow velocities generating sufficient turbulence to minimize solids deposition within the sewer. Commercial and industrial wastewater flows are also considered, but diversion of surface runoff to storm drains eliminates wet weather flow peaks of inefficient combined sewers. A force main or rising main

2760-571: The sewer pipes for inspection and maintenance, and as a means to vent sewer gases. They also facilitate vertical and horizontal angles in otherwise straight pipelines. Pipes conveying sewage from an individual building to a common gravity sewer line are called laterals. Branch sewers typically run under streets receiving laterals from buildings along that street and discharge by gravity into trunk sewers at manholes. Larger cities may have sewers called interceptors , receiving flow from multiple trunk sewers. Design and sizing of sanitary sewers considers

2820-410: The side. Sometimes parking on the sides of streets is allowed only at certain times. Curbside signs often state regulations about parking. Some streets, particularly in business areas, may have parking meters into which coins must be paid to allow parking in the adjacent space for a limited time. Other parking meters work on a credit card and ticket basis or pay and display . Parking lane markings on

2880-742: The sidewalk, or between the sidewalk and the curb. There may be a road verge (a strip of grass or other vegetation) between the carriageway (North American English: Roadway) and the pavement on either side of the street on which Grass or trees are often grown there for landscaping . These are often placed for beautification but are increasingly being used to control stormwater . Although primarily used for traffic, streets are important corridors for utilities such as electric power; communications such as telephone, cable television and fiber optic lines; storm and sanitary sewers ; and natural gas lines. Practically all public streets in Western countries and

2940-404: The street as a thoroughfare for vehicular traffic first and foremost. In this view, pedestrian traffic is incidental to the street's purpose; a street consists of a thoroughfare running through the middle (in essence, a road ), and may or may not have pavements (or sidewalks ) along the sides. In an even narrower sense, some may think of a street as only the vehicle-driven and parking part of

3000-400: The street is located in. On broader two-way streets, there is often a centre line marked down the middle of the street separating those lanes on which vehicular traffic goes in one direction from other lanes in which traffic goes in the opposite direction. Occasionally, there may be a median strip separating lanes of opposing traffic. If there is more than one lane going in one direction on

3060-461: The thoroughfare. Thus, sidewalks (pavements) and road verges would not be thought of as part of the street. A mother may tell her toddlers, "Don't go out into the street, so you don't get hit by a car." Among urban residents of the English-speaking world, the word "street" appears to carry only some of its original etymological connotations (i.e., the facilitation of traffic as a prime purpose, and "street life" as an incidental benefit). For instance,

3120-538: The travel lanes and the parking lanes, between the parking lanes and the curb, or for increased safety for cyclists, between curb and sidewalk. These poorer designs can lead to Dooring incidents and are unsafe for cycling. A more sensible design is found in the Netherlands with a Protected Bicycle Path totally separate from the traffic which is safe for cycling. Trams are generally considered to be environmentally friendly with tramlines running in streets with

3180-551: The use of grease interceptors by some customers) may also be necessary. The maintenance requirements vary with the type of sanitary sewer. In general, all sewers deteriorate with age, but infiltration and inflow are problems unique to sanitary sewers, since both combined sewers and storm drains are sized to carry these contributions. Holding infiltration to acceptable levels requires a higher standard of maintenance than necessary for structural integrity considerations of combined sewers. A comprehensive construction inspection program

3240-668: The verges of Roman roads and these settlements often became named Stretton . In the Middle Ages , a road was a way people travelled, with street applied specifically to paved ways. The street is a public easement , one of the few shared between all sorts of people. As a component of the built environment as ancient as human habitation, the street sustains a range of activities vital to civilization . Its roles are as numerous and diverse as its ever-changing cast of characters. Streets can be loosely categorized as main streets and side streets . Main streets are usually broad with

3300-591: The waste stream is pressurized, they can be laid just below the ground surface along the land's contour. Where it is impossible or impractical to discharge sewage from a property into a gravity sanitary sewer, a pressure sewer may provide an alternative means of connection. A macerator pump in a pumping well close to the property ejects sewage through a small diameter high pressure pipe into the nearest gravity sewer. Simplified sanitary sewers consist of small-diameter pipes, typically around 100 millimetres (4 in), often laid at fairly flat gradients (1 in 200). Although

3360-413: The ways that interaction among the people who live and work on a particular street—" eyes on the street "—can reduce crime, encourage the exchange of ideas, and generally make the world a better place. A street can often serve as the catalyst for the neighborhood 's prosperity, culture and solidarity . New Orleans ' Bourbon Street is famous not only for its active nightlife but also for its role as

3420-532: Was built to connect distant towns was named a "street" but originally never was in the truest sense. Some roads of this type which later became designated as numbered highways, became identified as said highway and may continue to colloquially be labelled as such from force of habit even if sections of it are subsequently urbanized and become an actual street and has its highway status decommissioned . Hurontario Street in Mississauga , Ontario , Canada (which

3480-464: Was formerly Ontario Highway 10 , but predates it), is an example of this. In some other English-speaking countries, such as Australia and New Zealand, cities are often divided by a main "Road", with "Streets" leading from this "Road", or the cities are divided by thoroughfares known as "Streets" or "Roads" with no apparent differentiation between the two. In Auckland in New Zealand, for example,

3540-409: Was impractical. Combined sewers were built to use surface runoff to flush waste off streets and move it underground to places distant from populated areas. Sewage treatment became necessary as population expanded, but increased volumes and pumping capacity required for treatment of diluted waste from combined sewers is more expensive than treating undiluted sewage. Communities that have urbanized in

3600-438: Was said, would allow for even denser development in the future. These plans were never implemented comprehensively, a fact which today's urban theorists regard as fortunate for vitality and diversity . Rather, vertical segregation is applied on a piecemeal basis, as in sewers , utility poles , depressed highways, elevated railways, common utility ducts , the extensive complex of underground malls surrounding Tokyo Station and
