Road design that restricts the passage of certain types of vehicle
A modal filter, sometimes referred to as a point closure,[1] is a road design that restricts the passage of certain types of vehicle in road transport. 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]
