ABSTRACT
A grid is two sets of axes organised into a larger pattern where each group is oriented in a different direction. In urban design, the grid is an ordering principle used to organise urban form and structure urban development through street and lot patterns. The arrangement of street to lot arrangement is called the grid morphology. We use grids to measure, divide, and distribute land as well as to organise movement through circulation infrastructure such as roads and streets. Regular grids occur where the circulation infrastructure runs at ninety degrees to each other in a regular pattern. It is also called gridiron and does not meet in any central place or have a focal point. Radial grids occur when the rays extending outwards from a centre are combined with concentric circles also moving outwards. The point where the rays and circles meet creates intersections and a grid structure.
