Los Angeles
–
Los Angeles, officially the City of Los Angeles and often known by its initials L. A. is the cultural, financial, and commercial center of Southern California. With a census-estimated 2015 population of 3,971,883, it is the second-most populous city in the United States, Los Angeles is also the seat of Los Angeles County, the most populated county in the United States. The citys inhabitants are referred to as Angelenos, historically home to the Chumash and Tongva, Los Angeles was claimed by Juan Rodríguez Cabrillo for Spain in 1542 along with the rest of what would become Alta California. The city was founded on September 4,1781, by Spanish governor Felipe de Neve. It became a part of Mexico in 1821 following the Mexican War of Independence, in 1848, at the end of the Mexican–American War, Los Angeles and the rest of California were purchased as part of the Treaty of Guadalupe Hidalgo, thereby becoming part of the United States. Los Angeles was incorporated as a municipality on April 4,1850, the discovery of oil in the 1890s brought rapid growth to the city. The completion of the Los Angeles Aqueduct in 1913, delivering water from Eastern California, nicknamed the City of Angels, Los Angeles is known for its Mediterranean climate, ethnic diversity, and sprawling metropolis. Los Angeles also has an economy in culture, media, fashion, science, sports, technology, education, medicine. A global city, it has been ranked 6th in the Global Cities Index, the city is home to renowned institutions covering a broad range of professional and cultural fields, and is one of the most substantial economic engines within the United States. The Los Angeles combined statistical area has a gross metropolitan product of $831 billion, making it the third-largest in the world, after the Greater Tokyo and New York metropolitan areas. The city has hosted the Summer Olympic Games in 1932 and 1984 and is bidding to host the 2024 Summer Olympics and thus become the second city after London to have hosted the Games three times. The Los Angeles area also hosted the 1994 FIFA mens World Cup final match as well as the 1999 FIFA womens World Cup final match, the mens event was watched on television by over 700 million people worldwide. The Los Angeles coastal area was first settled by the Tongva, a Gabrielino settlement in the area was called iyáangẚ, meaning poison oak place. Gaspar de Portolà and Franciscan missionary Juan Crespí, reached the present site of Los Angeles on August 2,1769, in 1771, Franciscan friar Junípero Serra directed the building of the Mission San Gabriel Arcángel, the first mission in the area. The Queen of the Angels is an honorific of the Virgin Mary, two-thirds of the settlers were mestizo or mulatto with a mixture of African, indigenous and European ancestry. The settlement remained a small town for decades, but by 1820. Today, the pueblo is commemorated in the district of Los Angeles Pueblo Plaza and Olvera Street. New Spain achieved its independence from the Spanish Empire in 1821, during Mexican rule, Governor Pío Pico made Los Angeles Alta Californias regional capital

Tram
–
A tram is a rail vehicle which runs on tracks along public urban streets, and also sometimes on a segregated right of way. The lines or networks operated by tramcars are called tramways, Tramways powered by electricity, the most common type historically, were once called electric street railways. However, trams were used in urban areas before the universal adoption of electrification. Tram lines may run between cities and/or towns, and/or partially grade-separated even in the cities. Very occasionally, trams also carry freight, Tram vehicles are usually lighter and shorter than conventional trains and rapid transit trains, but the size of trams is rapidly increasing. Some trams may also run on railway tracks, a tramway may be upgraded to a light rail or a rapid transit line. For all these reasons, the differences between the modes of rail transportation are often indistinct. In the United States, the tram has sometimes been used for rubber-tired trackless trains. Today, most trams use electrical power, usually fed by a pantograph, in some cases by a sliding shoe on a third rail. If necessary, they may have dual power systems — electricity in city streets, trams are now included in the wider term light rail, which also includes segregated systems. The English terms tram and tramway are derived from the Scots word tram, referring respectively to a type of truck used in coal mines and the tracks on which they ran. The word tram probably derived from Middle Flemish trame, a Romanesque word meaning the beam or shaft of a barrow or sledge, the identical word la trame with the meaning crossbeam is also used in the French language. The word Tram-car is attested from 1873, although the terms tram and tramway have been adopted by many languages, they are not used universally in English, North Americans prefer streetcar, trolley, or trolleycar. The term streetcar is first recorded in 1840, and originally referred to horsecars, when electrification came, Americans began to speak of trolleycars or later, trolleys. The troller design frequently fell off the wires, and was replaced by other more reliable devices. The terms trolley pole and trolley wheel both derive from the troller, Modern trams often have an overhead pantograph mechanical linkage to connect to power, abandoning the trolley pole altogether. Conventional diesel tourist buses decorated to look like streetcars are sometimes called trolleys in the US, the term may also apply to an aerial ropeway, e. g. the Roosevelt Island Tramway. Over time, the trolley has fallen into informal use

Interurban
–
The interurban is a type of electric railway, with streetcar-like light electric self-propelled railcars which run within and between cities or towns. They were prevalent in North America between 1900 and 1925 and were used primarily for travel between cities and their surrounding suburban and rural communities. Limited examples existed in Europe and Asia, Interurban as a term encompassed the companies, their infrastructure, and the cars that ran on the rails. The interurban, especially in the United States, was a cultural institution. Most roads and town streets were unpaved, and transportation was by horse-drawn carriages, the interurban provided vital transportation links between the city and countryside. In 1915,15,500 miles of railways were operating in the United States. For a time, interurban railways were the fifth-largest industry in the United States, by 1930, most interurbans were gone, with few surviving into the 1950s. The term interurban was coined by Charles L. Henry, a senator in Indiana. The Latin, inter urbes, means between cities, the interurban fit on a continuum between urban street railways and full-fledged railroads. George W. Hilton and John F, Due identified four characteristics of an interurban, Electric power for propulsion. Passenger service as the primary business, equipment heavier and faster than urban streetcars. Operation on tracks in city streets, and in areas on roadside tracks or private right-of-way. The definition of interurban is necessarily blurry, there was a large amount of consolidation of lines following initial construction. In 1905 the United States Census Bureau defined an interurban as a railway having more than half its trackage outside municipal limits. It drew a distinction between interurban and suburban railroads, a suburban system was oriented toward a city center in a single urban area and served commuter traffic. A regular railroad moved riders from one city center to city center. The typical interurban similarly served more than one city, but it served a smaller region and made frequent stops. The 1880s and saw the first successful deployments of electric traction in streetcar systems, most of these built on the pioneering work of Frank J. Sprague, who developed an improved method for mounting an electric traction motor and using a trolley pole for pickup

Bus
–
A bus is a road vehicle designed to carry many passengers. Buses can have a capacity as high as 300 passengers, many types of buses, such as city transit buses and inter-city coaches, charge a fare. Other types, such as elementary or secondary school buses or shuttle buses within a post-secondary education campus do not charge a fare, in many jurisdictions, bus drivers require a special licence above and beyond a regular drivers licence. Horse-drawn buses were used from the 1820s, followed by steam buses in the 1830s, the first internal combustion engine buses, or motor buses, were used in 1895. Recently, interest has been growing in hybrid electric buses, fuel cell buses, as of the 2010s, bus manufacturing is increasingly globalised, with the same designs appearing around the world. Bus is a form of the Latin word omnibus. The first horse-drawn omnibus service was started by a businessman named Stanislas Baudry in the French city of Nantes in 1823, Nantes citizens soon gave the nickname omnibus to the vehicle. The omnibus in Nantes was a success and Baudry moved to Paris, a similar service was introduced in London in 1829. The first mechanically propelled omnibus appeared on the streets of London on 22 April 1833, in parallel to the development of the bus was the invention of the electric trolleybus, typically fed through trolley poles by overhead wires. The Siemens brothers, William in England and Ernst Werner in Germany, sir William first proposed the idea in an article to the Journal of the Society of Arts in 1881 as an. arrangement by which an ordinary omnibus. The first such vehicle, the Electromote, was made by his brother Dr. Ernst Werner von Siemens and presented to the public in 1882 in Halensee, Germany. Although this experimental vehicle fulfilled all the criteria of a typical trolleybus. Max Schiemann opened a trolleybus in 1901 near Dresden, in Germany. Although this system operated only until 1904, Schiemann had developed what is now the standard trolleybus current collection system, in the early days, a few other methods of current collection were used. Leeds and Bradford became the first cities to put trolleybuses into service in Great Britain on 20 June 1911, in Siegerland, Germany, two passenger bus lines ran briefly, but unprofitably, in 1895 using a six-passenger motor carriage developed from the 1893 Benz Viktoria. Another commercial bus line using the same model Benz omnibuses ran for a time in 1898 in the rural area around Llandudno. Daimler also produced one of the earliest motor-bus models in 1898, the vehicle had a maximum speed of 18 kph and accommodated up to 20 passengers, in an enclosed area below and on an open-air platform above. With the success and popularity of bus, Daimler expanded production, selling more buses to companies in London and, in 1899, to Stockholm

Trolleybus
–
A trolleybus is an electric bus that draws power from overhead wires using spring-loaded trolley poles. Two wires and poles are required to complete the electrical circuit and this differs from a tram or streetcar, which normally uses the track as the return path, needing only one wire and one pole. They are also distinct from other kinds of buses, which usually rely on batteries. Power is most commonly supplied as 600-volt direct current, but there have been, currently, around 300 trolleybus systems are in operation, in cities and towns in 43 countries. Altogether, more than 800 trolleybus systems have existed, but not more than about 400 concurrently, the trolleybus dates back to 29 April 1882, when Dr. Ernst Werner Siemens demonstrated his Elektromote in a Berlin suburb. This experiment continued until 13 June 1882, after there were few developments in Europe. In 1899, another vehicle which could run either on or off rails was demonstrated in Berlin, routes followed in Eberswalde and Fontainebleau. Max Schiemann on 10 July 1901 opened the worlds fourth passenger-carrying trolleybus system, although this system operated only until 1904, Schiemann had developed what is now the standard trolleybus current collection system. In the early days there were a few methods of current collection. The Cédès-Stoll system was operated near Dresden between 1902 and 1904, and in Vienna, the Lloyd-Köhler or Bremen system was tried out in Bremen, and the Cantono Frigerio system was demonstrated near Milan. Throughout the period, trackless freight systems and electric canal boats were also built, Leeds and Bradford became the first cities to put trolleybuses into service in Great Britain on 20 June 1911. Apparently, though it was opened on 20 June, the public was not admitted to the Bradford route until the 24th, Bradford was also the last to operate trolleybuses in the UK, the system closing on 26 March 1972. The last rear-entrance trolleybus in Britain was also in Bradford and is now owned by the Bradford Trolleybus Association, birmingham was the first to replace a tram route with trolleybuses, while Wolverhampton, under the direction of Charles Owen Silvers, became world-famous for its trolleybus designs. There were 50 trolleybus systems in the UK, Londons being the largest, by the time trolleybuses arrived in Britain in 1911, the Schiemann system was well established and was the most common, although the Cédès-Stoll system was tried in West Ham and in Keighley. Smaller trackless trolley systems were built in the US early as well, the trackless trolley was often seen as an interim step, leading to streetcars. Buses and trolleybuses in particular were seen as entry systems that could later be upgraded to rail as appropriate, some trolleybus lines in the United States came into existence when a trolley or tram route did not have sufficient ridership to warrant track maintenance or reconstruction. In a similar manner, a proposed tram scheme in Leeds, worldwide, around 300 cities or metropolitan areas are served by trolleybuses today. See also Trolleybus usage by country, for example, new systems opened in Lecce, Italy, in 2012 and in Malatya, Turkey, in 2015

Bus rapid transit
–
Bus rapid transit is a bus-based public transport system designed to improve capacity and reliability relative to a conventional bus system. BRT aims to combine the capacity and speed of a metro with the flexibility, lower cost, the first BRT system was the Rede Integrada de Transporte in Curitiba, Brazil, which entered service in 1974. This inspired many similar systems around Brazil and the world, such as TransMilenio in Bogotá, Colombia, as of November 2016, a total of 207 cities in six continents have implemented BRT systems, accounting for 5,468 km of BRT lanes. The Latin American countries with the most daily ridership are Brazil, Colombia, in the other regions, China and Iran also stand out. Currently, TransJakarta considered as the longest BRT route in the world with approximately 210 kilometres length connecting the Indonesian capital city, BRT uses buses on a wide variety of rights-of-way, including mixed traffic, dedicated lanes on surface streets, and busways separated from traffic. Critics have charged that the bus rapid transit has sometimes been misapplied to systems that lack most or all the essential features which differentiate it from conventional bus services. The first BRT system in the world was the Rede Integrada de Transporte, implemented in Curitiba, Brazil, most of the elements that have become associated with BRT were innovations first suggested by Curitiba Mayor Architect Jaime Lerner. Other systems made further innovations, including platooning in Porto Alegre, in the United States, BRT began in 1977, with Pittsburghs South Busway, operating on 4.3 miles of exclusive lanes. Its success led to the Martin Luther King Jr, east Busway in 1983, a fuller BRT deployment including a dedicated busway of 9.1 miles, traffic signal preemption, and peak service headway as low as two minutes. After the opening of the West Busway,5.1 miles in length in 1990, new Orleans ran buses on Canal Street in a dedicated right of way beginning in the 1960s. This style of service was maintained until 2004 when streetcar service was restored on this 4-mile route segment, in 1995, Quito, Ecuador, opened trolleybus BRT. The success of TransMilenio spurred other cities to develop high quality BRT systems, in January 2004 the first BRT in Asia, TransJakarta, opened in Jakarta, Indonesia. As of 2015, at 210 kilometres, it is the longest BRT system in the world, africas first BRT system was opened in Lagos, Nigeria, in March 2008 but is considered as a light BRT system by many people. Johannesburg’s BRT, Rea Vaya, was the first true BRT in Africa, in August 2009, Rea Vaya and MIO were the first two systems to combine full BRT with some services that also operated in mixed traffic, then joined the BRT trunk infrastructure. BRT systems normally include most of the features, Bus-only lanes make for faster travel. Separate rights of way may be elevated, in a cutting, or in a tunnel, Transit malls or bus streets may also be created in city centers. Centre of roadway or bus-only corridor keeps buses away from the busy curb-side, fare prepayment at the station, instead of on board the bus, eliminates the delay caused by passengers paying on board. Prohibiting turns for traffic across the bus lane significantly reduces delays to the buses, Bus priority will often be provided at signalized intersections to reduce delays by extending the green phase or reducing the red phase in the required direction compared to the normal sequence

Track gauge
–
In rail transport, track gauge is the spacing of the rails on a railway track and is measured between the inner faces of the load-bearing rails. All vehicles on a network must have running gear that is compatible with the track gauge, as the dominant parameter determining interoperability, it is still frequently used as a descriptor of a route or network. There is a distinction between the gauge and actual gauge at some locality, due to divergence of track components from the nominal. Railway engineers use a device, like a caliper, to measure the actual gauge, the nominal track gauge is the distance between the inner faces of the rails. In current practice, it is specified at a distance below the rail head as the inner faces of the rail head are not necessarily vertical. In some cases in the earliest days of railways, the company saw itself as an infrastructure provider only. Colloquially the wagons might be referred to as four-foot gauge wagons, say and this nominal value does not equate to the flange spacing, as some freedom is allowed for. An infrastructure manager might specify new or replacement track components at a variation from the nominal gauge for pragmatic reasons. Track is defined in old Imperial units or in universally accepted metric units or SI units, Imperial units were established in United Kingdom by The Weights and Measures Act of 1824. In addition, there are constraints, such as the load-carrying capacity of axles. Narrow gauge railways usually cost less to build because they are lighter in construction, using smaller cars and locomotives, as well as smaller bridges, smaller tunnels. Narrow gauge is often used in mountainous terrain, where the savings in civil engineering work can be substantial. Broader gauge railways are generally expensive to build and require wider curves. There is no single perfect gauge, because different environments and economic considerations come into play, a narrow gauge is superior if ones main considerations are economy and tight curvature. For direct, unimpeded routes with high traffic, a broad gauge may be preferable, the Standard, Russian, and 46 gauges are designed to strike a reasonable balance between these factors. In addition to the general trade-off, another important factor is standardization, once a standard has been chosen, and equipment, infrastructure, and training calibrated to that standard, conversion becomes difficult and expensive. This also makes it easier to adopt an existing standard than to invent a new one and this is true of many technologies, including railroad gauges. The reduced cost, greater efficiency, and greater economic opportunity offered by the use of a common standard explains why a number of gauges predominate worldwide

Narrow-gauge railway
–
A narrow-gauge railway is a railway with a track gauge narrower than the 1,435 mm of standard gauge railways. Most existing narrow-gauge railways are between 600 mm and 1,067 mm, narrow-gauge railways also have specialized use in mines and other environments where a very small structure gauge makes a very small loading gauge necessary. Narrow-gauge railways also have general applications. Many narrow-gauge street tramways are used, particularly in Europe, where 1,000 mm metre gauge tramways are common, the earliest recorded railway is shown in the De re metallica of 1556, which shows a mine in Bohemia with a railway of about 2 ft gauge. During the 16th century, railways were mainly restricted to hand-pushed narrow-gauge lines in mines throughout Europe, during the 17th century, mine railways were extended to provide transportation above ground. These lines were industrial, connecting mines with nearby transportation points and these railways were usually built to the same narrow gauge as the mine railways from which they developed. The worlds first steam locomotive on rails, built in 1802 by Richard Trevithick for the Coalbrookdale Company, during the 1820s and 1830s, a number of industrial narrow-gauge railways in the United Kingdom used steam locomotives. In 1842, the first narrow-gauge steam locomotive outside the UK was built for the 1,100 mm gauge Antwerp-Ghent Railway in Belgium, historically, many narrow-gauge railways were built as part of specific industrial enterprises and were primarily industrial railways rather than general carriers. Some common uses for these industrial narrow-gauge railways were mining, logging, construction, tunnelling, quarrying, extensive narrow-gauge networks were constructed in many parts of the world for these purposes. For example, mountain logging operations in the 19th century often used narrow-gauge railways to transport logs from mill sites to market, significant sugarcane railways still operate in Cuba, Fiji, Java, the Philippines, and Queensland. Narrow-gauge railway equipment remains in use for the construction of tunnels. Extensive narrow-gauge railway systems served the front-line trenches of both sides in World War I and they were a short-lived military application, and after the end of the war, the surplus equipment from these created a small boom in narrow gauge railway building in Europe. Narrow-gauge railways usually cost less to build because they are lighter in construction, using smaller cars and locomotives, as well as smaller bridges, smaller tunnels. Narrow gauge is often used in mountainous terrain, where the savings in civil engineering work can be substantial. It is also used in populated areas where the potential demand is too low for broader gauge railways to be economically viable. This is the case in some of Australia and most of Southern Africa, the use of such railways has almost vanished due to the capabilities of modern trucks. In many countries, narrow gauge railways were built as feeder or branch lines to feed traffic to more important standard gauge lines, the choice was often not between a narrow-gauge railway and a standard gauge one, but between a narrow-gauge railway and none at all. Some bulk commodities, such as coal, ore, and gravel, can be transshipped, but this still incurs time penalties

Monorail
–
A monorail is a railway in which the track consists of a single rail. The term is used to describe the beam of the system. Colloquially, the monorail is often used to describe any form of elevated rail or people mover. More accurately, the term refers to the style of track, not its elevation, with Mono meaning one, monorails have found applications in airport transfer and medium capacity metros. To differentiate monorails from other modes, the Monorail Society says “Monorail n. A single rail serving as a track for passenger or freight vehicles, in most cases rail is elevated, but monorails can also run at grade, below grade or in subway tunnels. Vehicles either are suspended from or straddle a narrow guide way. Monorail vehicles are wider than the way that supports them. ”Monorails are often elevated, sometimes leading to confusion with other elevated systems such as the Docklands Light Railway, Vancouver SkyTrain and the AirTrain JFK. Monorail vehicles often appear similar to light vehicles, and can be staffed or unstaffed. They can be individual rigid vehicles, articulated single units, or multiple units coupled into trains, unlike some trams and light rail systems, modern monorails are always separated from other traffic and pedestrians. From the passengers perspective, monorails can have advantages over trains, buses. As with other grade-separated transit systems, monorails avoid red lights, intersection turns, as with other elevated transit systems, monorail passengers enjoy sunlight and views and by watching for familiar landmarks, they can know better when to get off to reach their destinations. As with other systems, expensive and noisy ventilation systems are not necessary if the cars have traditional windows that can be opened by passengers, monorails can be quieter than diesel buses and trains. They obtain electricity from the structure, eliminating costly and unsightly overhead power lines and poles. Compared to the train systems of New York, Chicago and elsewhere. See Chicago L Under the Monorail Society beam width criterion, some but not all systems are considered monorails, such as the Transrapid. Maglevs differ from other monorails in that they do not physically contact the beam, the first monorail prototype was made in Russia in 1820 by Ivan Elmanov. Attempts at creating monorail alternatives to conventional railways have been made since the part of the 19th century

Long Beach, California
–
Long Beach is the 36th most populous city in the United States and the 7th most populous in California. It is located on the Pacific Coast of the United States, as of 2010, its population was 462,257. Long Beach is the second largest city in the Los Angeles metropolitan area, the Port of Long Beach is the second busiest container port in the United States and is among the worlds largest shipping ports. The city also maintains a progressively declining oil industry with minor wells located both directly beneath the city as well as offshore, manufacturing sectors include those in aircraft, automotive parts, electronic equipment, audiovisual equipment, petrochemicals, precision metals and home furnishings. Long Beach lies in the corner of Los Angeles County. Downtown Long Beach is approximately 22 miles south of Downtown Los Angeles, indigenous people have lived in coastal Southern California for over 10,000 years, and several successive cultures have inhabited the present-day area of Long Beach. By the 16th-century arrival of Spanish explorers, the dominant group were the Tongva people and they had at least three major settlements within the present-day city. Tevaaxaanga was a settlement near the Los Angeles River, while Ahwaanga and Povuunga were coastal villages. Along with other Tongva villages, they were forced to relocate in the century due to missionization, political change. In 1784 the Spanish Empires King Carlos III granted Rancho Los Nietos to Spanish soldier Manuel Nieto, the Rancho Los Cerritos and Rancho Los Alamitos were divided from this territory. The boundary between the two ran through the center of Signal Hill on a southwest to northeast diagonal. A portion of western Long Beach was originally part of the Rancho San Pedro and its boundaries were in dispute for years, due to flooding changing the Los Angeles River boundary, between the ranchos of Juan Jose Dominguez and Manuel Nieto. In 1843 Jonathan Temple bought Rancho Los Cerritos, having arrived in California in 1827 from New England and he built what is now known as the Los Cerritos Ranch House, a still-standing adobe which is a National Historic Landmark. Temple created a cattle ranch and prospered, becoming the wealthiest man in Los Angeles County. Both Temple and his house played important local roles in the Mexican–American War. On an island in the San Pedro Bay, Mormon pioneers made an attempt to establish a colony. Two years previous Flint, Bixby & Co had also purchased along with Northern California associate James Irvine, to manage Rancho Los Cerritos, the company selected Lewellyns brother Jotham Bixby, the Father of Long Beach. Three years later Bixby bought into the property and would form the Bixby Land Company

San Fernando Valley
–
The San Fernando Valley is an urbanized valley located in Los Angeles County, California, defined by the mountains of the Transverse Ranges circling it. Home to 1.8 million people, it lies north of the larger, nearly two thirds of the valleys land area is part of the city of Los Angeles. The other incorporated cities in the valley are Glendale, Burbank, San Fernando, Hidden Hills, the Los Angeles River begins at the confluence of Calabasas Creek and Bell Creek, between Canoga Park High School and Owensmouth Ave. in Canoga Park. These creeks headwaters are in the Santa Monica Calabasas foothills, the Simi Hills Hidden Hills, Santa Susana Field Laboratory, the river flows eastward along the southern regions of the Valley. One of the rivers two unpaved sections can be found at the Sepulveda Basin, a seasonal river, the Tujunga Wash, drains much of the western facing San Gabriel Mountains and passes into and then through the Hansen Dam Recreation Center in Lake View Terrace. It flows south along the Verdugo Mountains through the communities of the valley to join the Los Angeles River in Studio City. Other notable tributaries of the river include Dayton Creek, Caballero Creek, Bull Creek, Pacoima Wash, the elevation of the floor of the valley varies from about 600 ft to 1,200 ft above sea level. Universal City, an enclave in the part of the valley, is unincorporated land housing the Universal Studios filming lot. Mulholland Drive, which runs along the ridgeline of the Santa Monica Mountains, in this Mediterranean climate, post-1790s European agriculture for the missions support consisted of grapes, figs, olives, and general garden crops. The San Fernando Valley contains five incorporated cities—Glendale, Burbank, San Fernando, Hidden Hills and Calabasas—and part of a sixth, Los Angeles, the unincorporated communities are governed by the County of Los Angeles. The Los Angeles city section of the valley is divided into seven city districts,2,3,4,5,6,7 and 12. Of the 95 neighborhood councils in the city,34 are in the valley, the valley is represented in the California State Legislature by seven members of the State Assembly and five members of the State Senate. The valley is divided into five congressional districts, the San Fernando Valley, for the most part, tends to support Democrats in state and national elections. This is especially true in the areas which include Sherman Oaks. The Los Angeles satellite administrative center for the valley, The Civic Center Van Nuys, is in Van Nuys. The area in and around the Van Nuys branch of Los Angeles City Hall is home to a station, municipal and superior courts. Northridge is home to California State University, Northridge, many branches of the Los Angeles Public Library are located in the valley. For independent libraries see Incorporated Cities in the Municipalities and districts list below, Los Angeles Police Department, Los Angeles County Sheriffs Department, and independent valley city departments
