Lambeth (Parliament Politics Magazine) – A new traffic filter will be added to the Streatham Hill Low Traffic Neighbourhood after a major rise in traffic and speeding, Lambeth officials confirmed.
Plans for a new traffic filter at the junction of Palace Road and Leigham Vale, part of the Streatham Hill LTN, have been issued by Lambeth Council.
The change to the existing program followed traffic monitoring which showed a considerable increase in cut-through traffic on areas of Palace Road and Probyn Road since the scheme was last examined, with over 3,700 cars a day traveling down Palace Road. Speeding is a serious problem for local people, with close to 40% of vehicles on Probyn Road breaching the limit, and 29% on Palace Road.
Councillor Rezina Chowdhury, Cabinet Member for Clean Air and Sustainable Lambeth said:
“Road danger and speeding are some of the top issues that residents talk to me about and the council is absolutely clear that we will take action to keep people safe.
We know that the Palace Road-Probyn Road cut-through is used by too many people to avoid the traffic lights on the gyratory. It’s not fair for small local streets to be used like this.”
The adoption of a new filter follows a legislative consultation on the ideas that took place earlier this year.
The new camera-enforced traffic filter will limit passing traffic to bikes, pedestrians and exempted vehicles, including the emergency services and Blue Badge Holders with an approved dispensation. The filter attempts to reduce traffic and road danger, producing a safe environment for individuals walking, wheeling and cycling.
Traffic monitoring on the system has previously revealed a 54% decrease in traffic on internal roads and a 5% decrease in traffic on neighboring main roads throughout the Streatham Hill LTN area. Cycling levels have also increased dramatically since the LTN was established, especially on Palace Road.
What traffic modelling supports the decision?
Lambeth Council’s decision to add a business sludge at Palace Road/ Leigham Vale in Streatham Hill LTN relies on pre- andpost-implementation business modelling from 2020- 2022, using automatic business counters( ATCs), ANPR cameras, and collision data analysis.
Models prognosticated rat- running relegation after original agronomists reduced internal LTN business by 5- 6( from 6,100 vehicles/ day), with boundary roads like Leigham Vale seeing 20- 30 volume increases and advanced speeding( 85th percentile pets exceeding 30mph limits).
Vaticinations incorporated Lambeth’s SATURN strategic model for network-wide impacts, validated by 6- month trial data showing safer cycling/ rambler routes but elevated boundary pitfalls near seminaries. Detailed reports, including raw ATC data, SATURN labors, and collision stats, are public via Lambeth’s discussion gate and FOI libraries. Post-2025 sludge modelling will modernize via periodic monitoring.
