TfL Ref: FOI-2150-1617
Thank you for your request received by Transport for London (TfL) on 3 February 2017 asking for information about congestion around Knightsbridge.
Your request has been considered in accordance with the requirements of the Environmental Information Regulations and our information access policy. I can confirm we hold some of the information you require.
The Knightsbridge, Brompton Road and Sloane Street area currently forms part of a major traffic signalling strategy to manage the challenging combination of works taking place on Knightsbridge and Brompton Road. Due to the lane restrictions in both directions, including the westbound bus lane and outside the Mandarin Oriental Hotel, it is currently necessary to run contingency traffic signal timings to assist traffic on Knightsbridge itself. This prevents regular queues developing towards the strategically important location of Hyde Park Corner, Piccadilly Underpass and Brompton Road. Traffic signal engineers regularly review the balance of green time in this area and have developed a strategy which best reduces the impacts of the works whilst managing competing demands.
Attached is the latest borough delay map that we have available for this area, it includes annualised data for 2014/15 and shows the average weekday delay (traffic) seen in the Royal Borough of Kensington and Chelsea. We are still in the process of compiling and collating the 2015/16 data and so, in accordance with Regulation 12(4)(d) we are not obliged to provide this information at this stage because the information is incomplete and in draft form.
The use of this exception is subject to the public interest test and, while we acknowledge the general presumption in favour of disclosure and the interest in our work to manage traffic and congestion in London, we feel that the balance of public interest lies in favour of withholding the information at this time to ensure that the information released into the public domain is fully verified and accurate to ensure that there is no adverse effect on local residents or businesses through misinterpretation or inaccuracy of the data available at this time. We anticipate this information to be available by the end of March, at which point we would be happy to disclose this information.
Please also see attached a spreadsheet detailing congestion control incidents at Knightsbridge station. When busy, generally during times of service disruption or events, the station may be subject to congestion control and part of this involves holding customers at one or more entrances. The station is still open but customer entry is restricted to avoid overcrowding on the platforms.
If this is not the information you are looking for, or if you are unable to access it for some 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
