Grid plan in the context of "Angle"

Adelaide (/ˈædɪleɪd/ AD-il-ayd; Kaurna: Tarndanya [ˈd̪̥aɳɖaɲa]) is the capital and most populous city of South Australia, as well as the fifth-most populous city in Australia. The name "Adelaide" may refer to either Greater Adelaide (including the Adelaide Hills) or the Adelaide city centre; the demonym Adelaidean is used to denote the city and the residents of Adelaide. The traditional owners of the Adelaide region are the Kaurna, with the name Tarndanya referring to the area of the city centre and surrounding Park Lands, in the Kaurna language. Adelaide is situated on the Adelaide Plains north of the Fleurieu Peninsula, between the Gulf St Vincent in the west and the Mount Lofty Ranges in the east. Its metropolitan area encompasses over 430 suburbs, extending 96 km (60 mi) from Gawler in the north to Sellicks Beach in the south and 20 km (12 mi) from the western coast to the eastern foothills of the Mount Lofty Ranges.

Named in honour of Adelaide of Saxe-Meiningen, wife of King William IV, the city was founded in 1836 as the planned capital for the only freely settled British province in Australia, distinguishing it from Australia's penal colonies. Colonel William Light, one of Adelaide's founding fathers, designed the city centre and chose its location close to the River Torrens. Light's design, now listed as national heritage, set out the city centre in a grid layout known as "Light's Vision", interspaced by wide boulevards and large public squares, and entirely surrounded by park lands. Colonial Adelaide was noted for its leading examples of religious freedom and progressive political reforms and became known as the "City of Churches" due to its diversity of faiths. It was Australia's third-most populous city until the postwar era.

Adelaide city centre (Kaurna: Tarndanya) is the city centre of Greater Adelaide, the capital city of South Australia. It is known by locals simply as "the City" or "Town" to distinguish it from Greater Adelaide and from the City of Adelaide local government area. The residential population was 18,202 in the 2021 census, with a local worker population of 130,404.

Adelaide city centre was planned in 1837 on a greenfield site following a grid layout, with streets running at right angles to each other. It covers an area of 4.33 square kilometres (1.67 square miles) and is surrounded by 6.68 square kilometres (2.58 square miles) of park lands. Within the city are five parks: Victoria Square in the exact centre and four other, smaller parks.

North Adelaide is a predominantly residential precinct and suburb of the City of Adelaide in South Australia, situated north of the River Torrens and within the Adelaide Park Lands. Laid out in a grid plan in three sections by Colonel William Light in 1837, the suburb contains many grand old mansions.

The Latin word insula (lit. 'island'; pl.: insulae) was used in Roman cities to mean either a city block in a city plan (i.e. a building area surrounded by four streets) or later a type of apartment building that occupied such a city block specifically in Rome and nearby Ostia. The latter type of Insulae were known to be prone to fire and rife with disease.

A standard Roman city plan was based on a grid of orthogonal (laid out on right angles) streets. It was founded on ancient Greek city models, described by Hippodamus. It was used especially when new cities were established, e.g. in Roman coloniae.

The borough of Manhattan in New York City contains 214 numbered east–west streets ranging from 1st to 228th, the majority of them designated in the Commissioners' Plan of 1811. These streets do not run exactly east–west, because the grid plan is aligned with the Hudson River, rather than with the cardinal directions. Thus, the majority of the Manhattan grid's "west" is approximately 29 degrees north of true west; the angle differs above 155th Street, where the grid initially ended. The grid now covers the length of the island from 14th Street north.

All numbered streets carry an East or West prefix – for example, East 10th Street or West 10th Street – which is demarcated at Broadway below 8th Street, and at Fifth Avenue at 8th Street and above. The numbered streets carry crosstown traffic. In general, but with numerous exceptions, even-numbered streets are one-way eastbound and odd-numbered streets are one-way westbound. Most wider streets, and a few of the narrow ones, carry two-way traffic.

Hippodamus of Miletus (/hɪˈpɒdəməs/; Greek: Ἱππόδαμος ὁ Μιλήσιος, Hippodamos ho Milesios; c.480–408 BC) was an ancient Greek architect, urban planner, physician, mathematician, meteorologist and philosopher, who is considered to be "the father of European urban planning", and the namesake of the "Hippodamian plan" (grid plan) of city layout, although rectangular city plans were in use by the ancient Greeks as early as the 8th c. BC.

Hippodamus was born in Miletus and lived during the 5th century BC. His father was Euryphon. According to Aristotle, Hippodamus was the first author who wrote upon the theory of government, without any knowledge of practical affairs.

Cycling infrastructure is all infrastructure cyclists are allowed to use. Bikeways include bike paths, bike lanes, cycle tracks, rail trails and, where permitted, sidewalks. Roads used by motorists are also cycling infrastructure, except where cyclists are barred such as many freeways/motorways. It includes amenities such as bike racks for parking, shelters, service centers and specialized traffic signs and signals. The more cycling infrastructure there is, the more people travel by bicycle.

Good road design, road maintenance and traffic management can make cycling safer and more useful. Settlements with a dense network of interconnected streets tend to be places for getting around by bike. Their cycling networks can give people direct, fast, easy and convenient routes.

14th Street is a major crosstown street in the New York City borough of Manhattan, traveling between Eleventh Avenue on Manhattan's West Side and Avenue C on Manhattan's East Side. It forms a boundary between several neighborhoods and is sometimes considered the border between Lower Manhattan and Midtown Manhattan.

At Broadway, 14th Street forms the southern boundary of Union Square. It is also considered the southern boundary of Chelsea, Flatiron/Lower Midtown, and Gramercy, and the northern boundary of Greenwich Village, Alphabet City, and the East Village. West of Third Avenue, 14th Street marks the southern terminus of western Manhattan's grid system. North of 14th Street, the streets make up a near-perfect grid that runs in numerical order. South of 14th, the grid continues in the East Village almost perfectly, except in Greenwich Village, where an older and less uniform grid plan applies.
