Adrienne Avenue (UB1) area is a low traffic neighbourhood (LTN) that was introduced in July 2020, on a trial basis, made possible with funding from Transport for London (TfL). There was significant concern that large numbers of people would drive in order to avoid contact with others on public transport due to social distancing measures. This could potentially lead to a large increase in rat-run traffic through this area.
Our streets are simply not designed for some of the high levels of traffic we are seeing on local roads. This is why the council is supporting residents to choose active travel like walking or cycling wherever possible, instead of taking shorter journeys in the car.
Evidence from across London and Ealing’s trials indicates that LTNs can help that change. LTNs can help to improve air quality and cutting down on harmful pollution that affects all of our health, our environment, and the climate. With reduced volumes of through traffic in neighbourhoods, it also can make using our roads and streets safer and more pleasant, making it easier to choose alternative, car free ways of getting around.
Description of the scheme
Changes to the design of the LTN were consulted on and improvements have been made based on recommendations of the interim assessment. These improvements include additional signage, installation of double yellow lines, removal of bollards, and removal of the initial planters located at the junction of Adrienne Avenue with Woodstock Avenue, with the closure north of junction on Adrienne Avenue.
Wooden planters have since been installed at thefollowing locations with accompaying signage to discourage through traffic:
- Woodstock Avenue/Adrienne Avenue junction
- Adrienne Avenue/Kenilworth Gardens junction.
The emergency services, refuse vehicles, pedestrians and cyclists remain unaffected and continue to have access through the road closures. All other vehicles may have to find alternative routes. Residents continue to have access by car to their properties, but this may be via alternative directions.
Data collected to assess the impacts of Adrienne Avenue’s LTN to April 2021
A summary of what the data indicates up to April 2021 for LTN 48: Adrienne Avenue is as follows:
Less than 100 comments were added to the dedicated Commonplace survey on LTN 48 by approximately 40 users made up of residents, and individuals who study, work, own a business and commute through the area.
23% indicated that they were in favour of the scheme, while 77% were against the proposals. Approximately 600 households are within the area affected by LTN 48, which includes boundary roads, equating to a response rate of less than 7%, notwithstanding that all responses were from residents.
The most cited concern was the generation of longer journeys due to a change in vehicle access, followed by an increase in traffic, and that the proposals would cause access issues for the emergency services.
LTN 48 was designed to prevent traffic heading north up Lady Margaret Road and then west along Ruislip Road from routing through residential streets and out onto Ruislip Road via Adrienne Avenue. The introduction of the LTN might therefore have been expected to have an effect on traffic levels and congestion on the northbound approach along Lady Margaret Road to its roundabout junction with Ruislip Road.
The iBus data and Floow traffic flow data for this stretch of road indicate that, since the LTN became established, neither traffic levels nor congestion are a cause for concern.
The council continues to meet regularly with the emergency services to discuss the LTNs and work collaboratively to ensure that they feedback into the schemes. In December 2020, the council agreed to remove all bollards and replace with CCTV enforcement as part of the LTNs interim assessment to ensure that any potential emergency service access issues were removed.
An increase in pollution was cited as another key concern. Data from air quality monitoring from the diffusion tube placed in LTN 48 demonstrate that NO2 mean concentration levels from both the LTN initiative and the baseline NO2 regular monitoring programme, over the same period, remain below the EU limit value of 40micrograms per cubic metre (µɡ/m³).
Analysis also reveals that anti-social behaviour and crime patterns in the LTNs followed a similar pattern across the borough overall, suggesting that the introduction of LTNs has not had an impact on overall crime levels.
Meanwhile, those in favour of the proposals did so as the scheme allows increased road safety and has led to a reduction in traffic.
During the same time, approximately 20 emails were also sent to the council, the majority of which asked for specific changes and voiced support for the schemes.

The final non-statutory consultation ended on 23 July 2021.
