You asked

Follow on from FOI-1741-1819 Firstly can you please clarify if 2021 journey times with no CS9 and Hammersmith Gyratory projects (minutes) Means a] 2021 journey times with no [CS9 and Hammersmith Gyratory projects] (minutes)] or b] 2021 journey times with Hammersmith Gyratory projects and no CS9 (minutes) what I am seeking for comparison is journey times with neither Hammersmith Gyratory projects nor CS9 in place. And I would like to restrict the work needed to retrieve the in formation requested so that it comes within the £450 / 18hours limit. So I am now asking for information from the following list, done in order, until the £450 is reached. It is for journey times with Hammersmith Gyratory projects in place and CS9 in place, compared with journey times with neither Hammersmith Gyratory projects nor CS9 in place. If the years have to be different , so be it. The following requests are for journey times for general traffic, AM peak and PM peak 1] From Fulham Road to Hammersmith Gyratory - northbound on Fulham Palace Road 2] From Hogarth Roundabout to Hammersmith Gyratory eastbound on Great West Road / Hammersmith Bridge Road 3] From Warwick Rd to Hammersmith Gyratory westbound on West Cromwell Rd / Talgarth Rd

TfL Ref: 1933-1819

Thank you for your email received by us on 24 October 2018 asking for information about traffic journey times with and without the Cycle Superhighways 9 (CS9) and the Hammersmith Gyratory projects place in reference to your previous request (reference: 1741-1819).

Your request has been considered in accordance with the requirements of the Environmental Information Regulations and our information access policy

2021 journey times with no CS9 and Hammersmith projects means that neither CS9 nor the Hammersmith Gyratory project is included in the modelling.

In terms of the information sought, we do not hold any of this information in the format requested. This requested data is outside of the scope of the modelling that has been undertaken and consulted on publicly. The reasoning behind the selection of the consulted routes, which have previously been sent to you, was that our network managers agreed they were a sufficient representation of the impact areas along the whole of the CS9 route. Journey time results were extracted and analysed for the main sections of the route, including key junctions where traffic is most likely to join or leave the CS9 route. We also wanted an understanding of the modelled impact immediately north and south of Hammersmith Gyratory, hence extracting and analysing journey time results between Charing Cross Hospital on Fulham Palace Road and Shepherd’s Bush Road.

Sites which are further away from the CS9 route, such as Hogarth Roundabout and Warwick Road, were not included in the scope for modelling because any journey time changes are less likely to be a result of the Scheme. As we explain in our public consultation material, modelling represents an indicative picture of the likely impact of any road network changes, but it is not intended to present a comprehensive or absolute prediction as to the performance of the road network once a scheme is built.

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
