Thank you for your request received on 16 October 2019 asking for information about Cheam crossroads.

Your request has been considered in accordance with the requirements of the Freedom of Information Act and our Information Access Policy. I can confirm we do hold the information you requested. You asked:

Please supply the transport appraisal carried out to inform the changes to the traffic lights sequencing and timing at Cheam village crossroads that were made in recent weeks, including assessment of journey time changes for road vehicles, impact on carbon emissions, impact on other emissions and local air quality. 

Please find attached the information you requested.

In accordance with the FOI Act, personal information has been redacted as it is subject to a statutory exemption to the right of access to information under section 40(2). This exemption to your right of access is applied in accordance with TfL’s obligations under the Data Protection Act 1998 (DPA).

The exemption applies because disclosure of personal information would be a breach of the DPA, specifically the first principle of the DPA which requires all processing of personal data to be fair and lawful.

Please see the attached information sheet for details of your right to appeal.

Yours sincerely,

Melissa Nichols
