Cycle Superhighways, rephasing of traffic signals

The request was successful.

Kevin Steinhardt

Dear Transport for London,

Does Transport for London plan to rephase traffic signals along the two trial Cycle Superhighways (CS3 and CS7) to allow a so-called 'green wave' for cyclists to occur?; a 'green wave' being a series of coordinated traffic signals that provide a 'wave' of green signals for road users if approached at a certain speed. I understand that TfL may not have authority of signal phasing along the entire length of both routes. Does TfL plan to implement this technology on the Cycle Superhighways before the opening of routes CS3 and/or CS7, or before the opening of future/planned routes?

Yours faithfully,
Kevin Steinhardt

Dear Mr Steinhardt

Thank you for your e-mail received by Transport for London (TfL) on 4
July 2010. You asked for information about the phasing of the traffic
signals along the planned Barclays Cycle Superhighways. Please accept my
apologies for the delay in my response.

Your request has been considered under the requirements of the Freedom of
Information Act and I can confirm that TfL does hold the information you
require.

As part TfL’s design of the Barclays Cycle Superhighways, a package of
safety measures and infrastructure improvements have been implemented to
significantly improve facilities for cyclists. As part of this work, TfL
has also considered the best use of traffic signal timings to optimise
journey times for cyclists, but any changes in this respect must also take
into account the surrounding road network so as not to cause disruption
and congestion elsewhere.

TfL has however reviewed the signal timings along CS3 and CS7 before they
were launched on 19 July, and the timings will predominantly be controlled
through our adaptive signal control system SCOOT (Split Cycle Offset
Optimisation Technique) and will be balanced to provide good progression
at our traffic signals for all users including cyclists and pedestrians.

While we have no current plans to progress the exact technology you refer
to, we remain committed to enhancing journeys for all road users,
including cyclists, through our wider remit of ‘Smoothing Traffic
Flow’, which is another of the Mayor’s strategies to improve transport
in London. Its basic concept is to provide Londoners with increased
reliability and predictability in their daily journeys, and to reduce
“stop-start” traffic conditions. This requires maximising the
efficient and reliable operation of the road network, including traffic
signal timings, to achieve safer and improved journeys throughout the
capital.

If this is not the information you are looking for please contact Graham
Hurt, Correspondence Support Manager - London Streets, at
[1][email address].

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
