Our Ref: FOI-4409-1718

Thank you for your further e-mail asking for information about speed cameras in 20mph limits in London.

Your request has been considered in accordance with the requirements of the Freedom of Information (FOI) Act and our information access policy. I can confirm that we do hold the information you require.

We are committed to keeping the Capital moving, working and growing and to achieve this we work in partnership with the police to deliver intelligence led enforcement activity. Our overriding focus is to keep London moving whilst ensuring the safety of all road users. We work closely with the police to enforce traffic regulations to keep traffic moving safely and efficiently for the benefit of all road users, supporting the economic life of the city.

We publish the location of speed cameras on our website:

https://tfl.gov.uk/corporate/safety-and-security/road-safety/safety-enforcement-cameras

All safety cameras in London are active except for sites currently undergoing modernisation and installation, or those that currently require work to be carried out due to faults or damage. In accordance with the FOI Act, we are not obliged to supply information on which speed cameras are not currently active as this is subject to a statutory exemption to the right of access to information under section 31(4)(a) and Section 31(4)(c).

In this instance the exemption has been applied as provision of this information would confirm where the restrictions will be enforced. The purpose of enforcement is to deter drivers from contravening restrictions so is focused on those areas of greatest risk, where compliance is low and where other traffic management initiatives have been unsuccessful. Disclosing information which reveals the activation status of safety cameras would lead to a decrease in compliance with traffic restrictions at those locations, which would adversely affect the flow of traffic on the network as well as the safety of other road users and impact on TfL’s Network Management Duty.

The use of this exemption is subject to an assessment of the public interest in relation to the disclosure of the information concerned. We recognise the need for openness and transparency by public authorities, but in this instance feel that balance lies in favour of withholding the information to ensure that we’re able to continue to comply with our Network Management Duty and ensuring the safety of all road users.

If this is not the information you are looking for, or if you are unable to access it for some reason, please feel free to contact me.

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

Yours sincerely
