When assessing buildings in Greater London, we would recommend using the PTAL map for the purpose of calculating the Public Transport Accessibility Index for the site, as per the link provided in the Methodology section of the manual, “Buildings in Greater London”
Please note that project teams must ensure that they use the version of PTAL that is current at the time the transport assessment is undertaken.

In this case, the Tra 01/02 tool will not be required for the assessment of this issue.
03 08 2022 - Updated to clarify that the version used must be current at the time of the transport assessment, but this does not need to be updated at post-construction stage
