A few more detials about CSHs:
Cycle Superhighways concept.
The basic concepts for CSHs are listed below:
(a) workplace offerings, such as business events, tailored packages for
employees and provision of cycle facilities;
(

home end offerings, such as marketing campaigns, tailored packages to individuals and residential cycle parking;
(c) cycle support for school leavers by encouraging students to cycle to
work once they leave school/college;
(d) targeting organisations with large numbers of HGV and freight drivers
who will travel along the CSHs by introducing measures to help avoid
collisions with cyclists;
(e) blue branding of routes – all relevant CSH infrastructure, including
surfacing material, signage etc. will be coloured blue;
(f) wide, continuous cycle lanes (new or improved), typically 1.5 metres
to 2.5 metres in width;
(g) continuous lanes through junctions, i.e. through junctions and slip
lanes where traffic joining or leaving has to cut across cyclists
travelling ahead;
(h) mirrors at traffic lights, known as Trixi mirrors, to prevent collisions
by revealing cyclists and pedestrians hidden in lorries' blind spots.
Their use is subject to Government approval and TfL is currently in
talks with the Department for Transport to secure the go ahead
following a series of accidents involving lorries turning left at
junctions;
(i) cycle-friendly studs/reflectors at potential conflict locations to
reinforce cycle lane markings and to raise awareness of cyclists to
turning motor vehicle drivers;
(j) entry treatments (raised carriageways) at side road junctions to
minimise the speed of turning vehicles;
(k) the closure of some side roads (with cycle access retained) to minimise conflict;
(l) possible diversions to avoid difficult junctions;
(m) speed restrictions, where locations have high activity/high risk and
reduce speed limit to 20mph where viable; and navigation measures, such as ‘spurs’ on roads off the CSH leading to other popular destinations and alternative routes through quiet roads, including links to London Cycle Network plus routes.
(n) other popular destinations and alternative routes through quiet roads,
including links to London Cycle Network plus routes.
