So you’ve got a Cycle Superhighway, or a junction on the London Cycle Network with a separate signal for cyclists to help people safely bypass the Elephant and Castle roundabout (as was).  But you can’t get across, even when the light is green. CSH and bus

The junction of Cycle Superhighway 7 with London Road is frequently blocked by stationary traffic when signals are showing a green light for cyclists and pedestrians to cross London Road. It’s inconvenient and dangerous. Pedestrians and cyclists who try to weave between the stopped buses and trucks can’t always be seen by drivers. The same problem occurs at the junction of Rockingham Street and Newington Causeway – but at this crossing there isn’t even any blue paint to alert drivers to the signalised crossing for cyclists. It seemed obvious that a yellow box indicating ‘keep the crossing clear’ would help alert drivers.

Green Party London Assembly Member Darren Johnson took up the problem with TfL and the London Mayor. This post on the Southwark Cyclists website describes a year of trying to get answers…
