Request ID: FOI-3097-2324 Date published: 11 January 2024
You asked
I am writing to request traffic count numbers on some of the vehicle bridges in the City of London i.e. Blackfriars, Tower and London. If possible could it be broken down into buses, private vehicles, emergency vehicles etc. and cover a few years (maybe including before the pandemic as well?). Also, is there any information about the frequency of collisions on these bridges. Thank you.
Clarification received 30/11/2023: Could I request the data for the past 5 years please?

Thank you for your request received by Transport for London (TfL) on 28th November 2023 asking for data on vehicles using central London bridges. Your request has been considered in accordance with the requirements of the Freedom of Information Act and our information access policy.
Specifically you asked:

I can confirm that we hold the information you require.
In regard to the request for traffic count data, please see the attached folder. This provides the traffic flow data from our digital camera sensors on Blackfriars Bridge, Tower Bridge and London Bridge split by mode (a classifications definitions breakdown also attached). The data from Blackfriars and Tower Bridges is from 14/05/20 and the data from London Bridge is from 12/04/21 (Southbound) and 03/12/21 (Northbound) as these were the dates when the sensors were installed. Please note this is raw data so there may be gaps in the data due to sensor outages.
In regard to collisions, please see our published ‘London Collision Map’ which can be found on page four of the Road Danger Reduction Dashboard. Data is available from 2017 to July 2023, which is the latest processed collision information available. You can use the + / - icons to zoom in and out of the map. In accordance with section 21 of the FOI Act, we are not obliged to supply you with a copy of the requested information as it is already accessible to you elsewhere.
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.
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 FOI Case Officer FOI Case Management Team General Counsel Transport for London
