I would like to request i) all traffic modelling made by TfL regarding the proposed ban to a left turn from Clapham Common South Side (A205) onto Cavendish Road (A24). TfL is proposing to re-route traffic around an existing gyratory and has stated that delays will be minimal. Other 500 residents have objected to this proposal and we would like to see all traffic models supporting this initial contention. ii) all traffic modelling conducted by TfL consequent to a left turn ban that assesses the impacts on the surrounding residential streets of Abbeville Village in terms of traffic flow, pollution, noise and reduced road safety for residents and schools.

TfL Ref: 3758-1920

Thank you for your request received by Transport for London (TfL) on 6 March 2020 asking for information about traffic modelling A205 Cavendish Road / Clapham Common South Side.

Your request has been considered in accordance with the requirements of the Environmental Information Regulations and our information access policy.  I can confirm that we hold some of the information you require.

Please find attached the traffic modelling files for this FOI request:

• R383 Base.lsg3x – Base model of the UTC region, validated to 2018 traffic flows
• R383 Pro (Straight Across – Sept 2018) – Proposed model with a straight crossing included
• R383 Pro (Stagger – Sept 2018) – Proposed model with a staggered crossing included
• R383 Pro (No left turn – Jun 2019) – Further iteration of the stagger model with left turning traffic re-routed around the gyratory.

No traffic reassignment modelling was undertaken, therefore the models we are sending do not include any impact on surrounding streets.

The Government has announced a series of measures to tackle the Coronavirus. It is essential for London, and in particular for all critical workers, that we continue to provide a safe transport network that enables them to make the journeys they need to.

In current circumstances, we are not able to answer FOI requests readily and we ask that you please do not make a request to us at present.

Answering FOI requests will require the use of limited resources and the attention of staff who could be supporting other essential activity. In any event, please note that our response time will be affected by the current situation.

If this is not the information you are looking for, or if you are unable to access it for any reason, please do not hesitate to contact me.

Please see the attached information sheet for details of your right to appeal as well as information on copyright and what to do if you would like to re-use any of the information we have disclosed.

Yours sincerely
