Info provided - 15 April 2016

Transport for London (TfL) is the traffic authority for traffic signals on the Transport for London Road Network (TLRN) and on roads for which the London boroughs are the highway authority. Therefore they are best placed to answer Questions 1, 3 and 5.

With regard to Question 2 regarding the operational cost of the signal stock on borough roads, TfL apportion this out between boroughs to cover the cost of maintaining and managing London's traffic signal system and for the financial year 2015/16 the London Borough of Richmond contributed £264,098.20 to TfL for this purpose.

With regard to Question 4, TfL is responsible for promoting new schemes, or changes to traffic signals on the TLRN and the Council is responsible for promoting new installations, or changes to traffic signals on borough roads. TfL, if they approve of the proposals, will then design and install the changes. The locations of currently proposed/prospective new installations that the borough is currently promoting (subject to consultation and approval) includes; new pedestrian crossing at Percy Road outside Twickenham Academy and Nelson Road/ Hanworth Road junction improvements. However we are also looking at a number of other locations and corridors as part of our accident investigation analysis and village planning work and some of this feasibility work may in due course also result in the borough promoting additional traffic signals installations.

TfL are responsible for the maintenance and management of all traffic signals and they will have a programme of all upcoming traffic signal modernisations.

Please note that our responses were accurate to the best of our knowledge at the time of release, and have not subsequently been updated. This information should be considered an historical record only.
