In Agenda Item 13, section 4.3 (a) of the papers found here: content.tfl.gov.uk/pic-20191023-agenda-and-papers-public.pdf, it states: "Traffic modelling has been undertaken and we have assessed the impact on the ULEX boundary. Evaluation of appropriate mitigations to address these impacts e.g. signal timings or highway amendments has commenced." For the removal of doubt the papers in question are the papers released by the TfL Programmes and Investment Committee for the 23 October 2019 meeting. Can you please provide the traffic modelling/assessment mentioned above and also the subsequent evaluation of the mitigation measures? If one of these documents cannot be provided, I would be satisfied with only one of them. Also, if for commercial reasons certain sections of the reports will have to be excluded, I would be happy to receive redacted versions that exclude any commercial details.

Thank you for your request received by Transport for London (TfL) on 6^th June 2020 asking for information about traffic modelling in connection with the extension of the ULEZ scheme.

Your request has been considered in accordance with the requirements of the Freedom of Information Act and our information access policy.

Specifically you asked:

“In Agenda Item 13, section 4.3 (a) of the papers found here: content.tfl.gov.uk/pic-20191023-agenda-and-papers-public.pdf, it states:

"Traffic modelling has been undertaken and we have assessed the impact on the ULEX boundary. Evaluation of appropriate mitigations to address these impacts e.g. signal timings or highway amendments has commenced."

Also, if for commercial reasons certain sections of the reports will have to be excluded, I would be happy to receive redacted versions that exclude any commercial details.”

I can confirm that we hold the information you require.

TfL has undertaken a detailed traffic modelling assessment to assess what the potential traffic displacement impacts of ULEZ Expansion might be on the boundary roads and those roads within a 2km buffer of it. Please find attached the full report and the executive summary. The full report requires a level of technical understanding, so the executive summary has been provided to help with interpretation.

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.

On a more general matter, please note that the Government has announced a series of measures to tackle the coronavirus. It is essential for London that we continue to provide a safe transport network for essential journeys.

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.

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,

David Wells
