The grid plan, also known as the grid street plan or gridiron design, is a sort of city layout in which streets run at right angles to one another, forming a grid. The grid plan extends back to antiquity and originated in a variety of civilizations; grid plans were used to construct some of the first planned towns. Modern cities around the world include small grids within their downtown areas.
In North America, the grid plan was developed by French colonists in Canada and by English settlers in the United States. The early French settlements were based on the cadastral survey system used by France when granting land grants. When building new houses or shops, builders would follow a uniform pattern and place them along straight lines with equal distances between buildings and streets. This method resulted in compact, self-sufficient communities that could support large armies during the wars with Britain and France.
English settlers built their own versions of the grid plan when they arrived in what is now the United States. They brought with them the tradition of planning towns in the British model and modified it to fit their needs. Some American colonies did not have unified governments until years after their founding, so most early cities were not planned by any official body but rather by private individuals or groups who wanted to create communities for themselves. These cities tended to be less organized than those founded by governments that had staff members responsible for planning and development.
A grid is a network of crossing parallel lines, which might be actual or fictitious. When viewed from above, most American streets are planned out in a grid layout, which means that the streets cross at right angles and form a pattern of squares. Cities around the world use a variety of different street layouts, but almost all cities have some sort of grid system for their roads.
Grid lines are the thin white or black stripes used by surveyors to mark property boundaries, sidewalks, and other physical features on land. The term "grid" comes from the fact that these lines form a checkerboard pattern when viewed from an airplane or satellite image.
The word "gridlock" comes from London, where it is used to describe a traffic jam on one of the city's many streets. There are several ways that this can happen; typically one or more streets may be closed off by accident or on purpose, causing drivers to slow down or stop moving altogether.
In mathematics, a grid is a set of equidistant points arranged in a matrix or array. A grid line is any horizontal or vertical line through which all the points in the grid fall. Mathematical grids are commonly used in calculating coordinates, such as in creating maps or designing experiments. They provide a convenient method for people to calculate distances between objects without having to measure each one individually.
A grid is something that is made up of straight lines that cross over one other to make squares. Many canals were constructed in accordance with map grid lines. The word comes from Latin graticula, meaning "little square." The term was originally used to describe maps that were divided into little squares or grids.
A grid is used in many different contexts within engineering and architecture. One example is street lighting: each light is placed at exactly the right distance from its neighbor, so that no gap is left between lights. The electrical wiring for these lights must be able to pass between them without touching any part of the fixture itself. This is done by placing the wires inside conduit, which is then sealed with rubber cement or tape. The conduits are placed on the grid so that they don't touch anything else. These are just two examples of how grids are used in technology.
There are several ways to define a grid. A grid is a system of points separated by fixed distances. Each point has an equal chance of being selected as the origin of coordinates. The line joining any two origins forms a coordinate axis. The intersection of any number of axes forms a cell. Cells can be considered the building blocks of the grid. There can be any number of axes; however, it is most common for there to be between three and seven.
Manhattan's street grid is a distinctive feature. The grid, which was established in 1811 to cover the island when New York was a small settlement at the southern point, was the city's first significant civic effort and a vision of audacious ambition. Over the next two decades, the city would extend its streets westward toward the Hudson River, forming a grid that was nearly identical to the one now used by motorists.
The original grid was designed by Pierre L'Enfant, the French-American architect who also planned Washington, D.C. For reasons that are not clear, his design was not followed exactly, so some deviations exist. However, even with these deviations, the overall effect is one of geometric order that serves as the foundation for much of Manhattan's development since then.
There are several theories on why L'Enfant chose to include diagonal streets in his plan. Some believe it was because it provided better access to farmland owned by prominent citizens of the day. Others think it was because he wanted to provide more room for public markets and sidewalks. Still others argue that it was due to cost savings: Diagonal streets do not have to be straightened after they have been laid out, which made them attractive for early cities without much infrastructure funding.
You've definitely seen a map grid, which is a series of uniform lines placed on a map that allows you to locate a certain spot. A "grid" can also refer to a physical network that isn't always made up of straight or parallel lines. For example, if I said the Brooklyn Bridge is a grid of iron girders, that wouldn't be completely wrong. Even though it wasn't designed by Benjamin Franklin or Thomas Jefferson, they still played important roles in its creation by providing guidance for its design and construction.
Grid has been used as a communication system since George Bell was able to send messages from his mountain station to Washington D.C. using a magnetic telegraph grid installed across the entire length of the Appalachian Trail. Magnetic telegraphs were eventually replaced by electrical telegraphs but the concept of using grids in communication systems has continued to evolve. Modern communication systems use computer networks instead but the idea of using solid lines or circuits to transmit information remains the same.
In mathematics, a grid is an array of cells or squares, each containing a number. The cells are arranged in rows and columns, with each cell having an entry in only one of these two arrays. A grid is thus represented by a 2-dimensional array of numbers. In physics, chemistry, and engineering, the term grid is used to describe a pattern of lines or points that divide space into equal parts.
