A modal filter in Basel, Switzerland

A modal filter, sometimes referred to as a point closure,[1] is a road design that restricts the passage of certain types of vehicle. Modal filtering is often used to help create a low traffic neighbourhood (LTN), where motor traffic is diverted away from residential streets[2][3] and instead toward feeder roads. Modal filters can be used to achieve filtered permeability within a transport network,[4][5][6] and can encourage walking and cycling through more pleasant environments and improved safety.[7]

Modal filters can be implemented through the use of barriers such as bollards, boom barriers and planters, though can also be implemented virtually through the use of automatic number-plate recognition cameras and road signs, which can allow residential motor access while prohibiting passing motor traffic.[4]
