Summary of the data collected to assess the impacts of low traffic neighbourhoods to April 2021

The council has been collecting data to form part of the review on whether to make Low Traffic Neighbourhoods (LTNs) installed in 2020 permanent. This excludes LTN 21: West Ealing South which had its trial ended early due to Hounslow council’s decision to close Swyncombe Avenue, making the trial unworkable.

From the evidence collected across the eight LTNs installed in 2020 to April 2021, the data indicates:

Resident feedback

  • Local opinions are mixed. Most schemes received more comments that raised concerns or objections than were in support. However, the response rates were usually less than 10%. Feedback from emails sent to the council and Commonplace reveal that the top reasons for not supporting the schemes is due to general dislike, followed by concerns relating to perceptions of poor/worsening air quality, explicitly relating to particulate matter and nitrogen dioxide, and perceptions of increasing congestion on LTN boundary roads. Meanwhile, those in favour of the LTNs cited that they support the schemes generally, as they support a reduction in traffic using residential roads, and as the schemes facilitate more people walking and cycling.

Traffic data

  • The available data clearly shows that traffic volumes and congestion on the majority of LTN boundary roads have not significantly increased and follow a similar pattern to other local B-roads, and therefore are not of concern. The exception to this is the westbound approach along Pope’s Lane to the South Ealing Road signals, although gasworks are believed to have contributed to the increase, and Lower Boston Road.

Air quality data

  • Air quality monitoring data shows that air pollution remains below the EU limit after the introduction of the LTNs.

Crime patterns

  • Analysis shows anti-social behaviour and crime patterns in LTNs follow a similar pattern across the borough overall, suggesting that the introduction of LTNs has not had an impact on overall crime levels. 

Please note further data will be added when made available.

Data for individual LTNs

Traffic volume changes on LTN boundary roads, measures of congestion on LTN boundary roads, air quality data, feedback from residents, and crime trend data is available per LTN up to April 2021:
