Low Traffic Neighbourhood

In the United Kingdom, a Low Traffic Neighbourhood (LTN) is an area in which filtered permeability and traffic calming are deployed to reduce motorised through-traffic in residential areas. Many LTNs were introduced in spring 2020, although the same principles had been in use in London since the 1970s.

LTNs can be implemented through the use of barriers such as bollards, boom barriers and planters; they can also be implemented virtually through the use of automatic number-plate recognition cameras and road signs, which can allow vehicle access for residents and emergency services while prohibiting unrelated through traffic.
