We answered

Our ref: FOI-2217-2021

Thank you for your request received by Transport for London (TfL) on 31 January 2021 asking for information SCOOT data for Lambeth.

Your request has been considered in accordance with the requirements of the Freedom of Information Act (FOIA) and our Information Access Policy. I can confirm we do hold the information requested.

Please find attached the SCOOT link flows for the requested sites.

Scoot Flows may differ flow other validated counts as the SCOOT system utilises loop occupancy as it primary source of data, this is then modelled into a flow count via an average occupancy per vehicle. This is often sensitive to over or under saturation,  e.g. when vehicles are sat over the detector for long period of time such as in congestion queuing at the lights. The detectors are often siting at a distance from the junction where this is minimised but sometime especially when junctions are close together this issue is exasperated. Therefore Scoot Flow should be used more to generalise trend of demands and not actual counts.

The data provided here is given as is and we are not able to validate these flows.

If you are considering submitting a further FOI request please think carefully about whether the request is essential at this current time, as answering FOI requests will require the use of limited resources and the attention of staff who could be supporting other essential activity. Where requests are made, please note that our response time may be impacted by the current situation.

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

Yours sincerely,

Melissa Nichols
