Taxicab geometry - Wikipedia, the free encyclopedia
"The taxicab metric is also known as rectilinear distance, L1 distance or L1 norm (see Lp space), city block distance, Manhattan distance, or Manhattan length, with corresponding variations in the name of the geometry.[1] The last name alludes to the grid layout of most streets on the island of Manhattan, which causes the shortest path a car could take between two points in the city to have length equal to the points' distance in taxicab geometry."
