A Low Traffic Neighbourhood (LTN) is a scheme implemented to reduce through traffic in residential areas through the use of filtered permeability and traffic calming.
LTNs 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.[1]
LTNs lead to a decrease in car use, increase in walking and cycling and a decrease in street crime, violent crime and sexual assaults.[2][3]
History
Previous to the COVID-19 pandemic, there were already at least 25,000 modal filters across the UK. Low-traffic neighbourhoods have been a common policy in designing new towns and communities in the UK since the 1960s.[4] During the COVID-19 pandemic of 2020–21, 72 low-traffic neighbourhoods with modal filters were rolled out under emergency legislation in London, covering a population of around 300,000. Waltham Forest had previously introduced a number of LTNs between 2015 and 2019.[5]
Impact
A study by cycling charity BikeIsBest found that communities in the majority of low-traffic neighbourhoods did not have concerns about the impact of traffic displacement or emergency services.[4]
Traffic
In London, prior to the Covid-19 pandemic, traffic had risen on side roads by over 100% since 2008.[6]
People in LTNs are becoming less likely to own a car, more likely to reduce their car usage.[2]
LTNs were implemented in Waltham Forest in 2014. A study by climate charity Possible found that in 2016 on three LTN 'boundary roads' recorded increases of traffic between around 2.6% and 28.3%. Two of the three roads were within the 'normal' range for recent fluctuations in traffic flow. For Sherhall Street, the only road studied that registered an increase, it was found that the 2016 traffic count was around the same as the 2009 traffic count for this road.[7]
Crime and safety
The introduction of LTNs leads to a decrease in total street crime, increasing with duration since implementation, and with no displacement to other areas. After 3 years of implementation, a study found an 18% decrease in street crime in LTN areas. A larger reduction was found for violent crimes and sexual assaults. Only a single subcategory for crime saw an increase – bicycle theft.[3]
Evidence suggests that LTNs lead to a three-fold reduction in injuries within LTN areas. Meanwhile, no evidence suggests that injury numbers change on boundary roads.[8]
Active travel
LTNs tend to encourage more active travel, shifting people from car use of these modes.[2] Emergency rapid-implemented LTNs see more walking, cycling and improved perceptions of the local cycling environment.[9]
Emergency vehicles
A 2020 study of the impact of the Waltham Forest LTN in London found no evidence that fire brigade emergency response times were affected inside LTNs and some evidence that they improved slightly on boundary roads, despite a perception among fire crews that traffic calming was the cause of some delays.[10] A 2021 study in Findings journal examined the impact of 72 LTNs in London on fire brigade emergency response times. It found no evidence that response times were affected for both LTNs that use physical barriers and those that use camera enforcement.[5]
Equity
LTN implementation since 2020 in London has been broadly equitable at the city and micro levels. The most deprived quarter are more likely to live in a newly opened LTN than people in the least deprived quarter. Ethnic minorities are more likely to live in a newly opened LTN than White people. London Boroughs have, on average, implemented LTNs in their most deprived districts.[11]
Criticism
.jpg)
Modal filters and low-traffic neighbourhoods have sometimes been criticised for a number of reasons. The British motoring magazine Auto Express criticised the schemes for their levels of cost, calling them a "waste of money". Other criticisms include high fines and a lack of consultation in implementing the scheme.[12]
In the UK, the implementation of low-traffic neighbourhoods has been compared to Brexit in its divisiveness.[13][14][15] The schemes have caused protests in multiple cities by anti-LTN activists.[16][17] The far right populist former actor Laurence Fox, who ran for Greater London Mayor in 2021, wanted to remove all modal filtering (even those in place before 2020) in London.[4] On this platform, Fox received just 1.9% of first round votes.[18] In Hackney, a candidate standing an anti-LTN platform in a by-election in Hoxton East and Shoreditch in May 2021 received fewer than 8% of votes, while in a byelection in St Peter's Ward in Islington an anti-LTN candidate received only 318 out of 4,395 of votes (7.2%).[19][20][21][22]
