In urban planning, the grid plan, grid street plan, or gridiron plan is a type of city plan in which streets run at right angles to each other, forming a grid. [1] Two inherent characteristics of the grid plan, frequent intersections and orthogonal geometry, facilitate movement.

2010年3月29日 · If you walk through most North American cities you'll find yourself on that very familiar grid of streets -- usually intersecting at 90 degree angles. But did you ever think about where the grid street pattern originated?

When seen from above, this pattern is made up of streets that connect at right angles to form squares. A physical network not always constructed of straight or parallel lines may also be called a grid. Regular grid systems often have greater infrastructure costs than those with disjointed street patterns. Fig 6: Grid Road Pattern

…out a city with a grid plan; it was oriented according to the compass, emphasizing a principal north-south street and including one or more major east-west streets. The ritual involved in thus laying out a town, complete with walls, temples, and …

Current thinking on street pattern design appears to be divided between concern for the efficiencies of infrastructure and traffic, and a consideration of aesthetics. This generally translates into a battle between conventional suburban loops and cul-de-sacs, and “traditional” grid models.

Research has shown that disconnected urban networks are associated with greater vehicle travel, energy use and emissions. A quantitative evaluation of the connectedness of street grids globally allows to identify 8 street-network types from the regular grid to …

The grid plan, grid street plan or gridiron plan is a type of city plan in which streets run at right angles to each other, forming a grid. The infrastructure cost for regular grid patterns is generally higher than for patterns with discontinuous streets.
