Ladbroke Square and Ladbroke Terrace - Proposed sinusoidal road hump traffic calming

Overview

Please read the following information carefully before filling in our consultation survey below, no later than Sunday 27 July 2025.

Following a successful application for Neighbourhood Community Infrastructure Levy (NCIL) funding by local residents, to introduce traffic calming in Ladbroke Square and Ladbroke Terrace, the Council is now seeking views on the proposals.

A portion of the Community Infrastructure Levy (CIL) is to be spent on local priorities; this is called Neighbourhood CIL (NCIL). This is a fund the Council collects from developments and is required to be spent in consultation with local communities in each ward.

Pembridge ward councillors Joanna Gardner and Dori Schmetterling supported the application and subsequently approved the proposal for consultation. They will consider the results of this consultation before taking a view on whether to proceed with the scheme.

Traffic calming proposal (using sinusoidal road humps):

The proposal is to install nine sinusoidal road humps, five on Ladbroke Square and four on Ladbroke Terrace. The approximate positions of the road humps and associated signs can be seen in the plan linked below.

Road humps with a sinusoidal profile are similar to round-top road humps but have a shallower initial rise. They minimise the potential noise impact of vehicles, particularly larger ones, passing over them. The profile also provides a more comfortable ride for cyclists. The sinusoidal profile is now the preferred standard for road humps in the borough.

It is important to avoid leaving gaps between humps, as this can lead to drivers accelerating between them and then braking hard. The humps proposed are no more than 60 meters apart, to encourage drivers to keep to a consistent speed as they negotiate them, thereby minimising any associated noise and emissions. The spacing of the humps will vary slightly as they need to be placed away from metal covers in the road and resident's driveways. 

You can view examples of recently installed sinusoidal road humps in Pembridge Square (W2) and Holland Park (W11).
