Filter is both a verb, meaning the act of passing through something or moving slowing in in a certain direction and a noun referring to a system by which object move in a certain direction or the object through which something passes. A filter is usually an object that can separate certain elements from one another, often removing unwanted parts or impurities such as particles from materials, liquids or gas that pass through.

In the design and construction of buildings and cities there are two common uses of the term the first relatvely simple application and the second with a wider set of applications.

In city, urban or traffic planning and management a filter may be used to refer to a system of traffic management, where by vehicles filter left or right with a certain design of road junction. or traffic light system. The term can also be used in the design of pedestrian traffic systems, also known as people-movement, where, routeways, layout, signage or indicators encourage pedestrians both in the urban realm and within circulation spaces of buildings, in one direction or a another.
