Bassett Road - Proposed sinusoidal road hump traffic calming

Overview

Please read the following information carefully before filling in our consultation survey below, no later than Sunday 8 March 2026.

Following a successful application by a resident of St Helen’s ward for Neighbourhood Community Infrastructure Levy (NCIL) funding to introduce traffic calming in Bassett Road (between St Helens Garden and Ladbroke Grove), the Council is now seeking the views of local residents on the proposals.

St Helen’s ward councillors supported the application and subsequently approved the proposal for consultation.

Traffic calming proposal (using sinusoidal road humps):

The proposal is to install seven sinusoidal road humps in Bassett Road - two between St Helen’s Gardens and St Mark’s Road, and five between St Mark’s Road and Ladbroke Grove. The approximate positions of the road humps and associated signs can be seen in the plan link below. If the scheme goes ahead, the final position of the humps may vary from the plan, subject to detailed design.

Road humps with a sinusoidal profile are similar to round-top road humps but have a shallower initial rise. They minimise the noise impact of vehicles passing over them and provide 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 large gaps between humps, as this can lead to drivers accelerating between them and then braking hard. The humps proposed are between 50 and 60 metres 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 residents' driveways.

You can view examples of recently installed sinusoidal road humps in Latimer Road (W10) Lexham Gardens (W8).
