I gotten so frustrated that while I am doing some of my part in saving the world & lessening traffic jams (sure there is more, but here I do not need to list them all) that when I come to an intersection with traffic lights & crosswalk lights, telling you when it is safe for you to cross, that I have to wait forever to right away to use the crosswalk! The lights are setup to give the BLANKING automobiles the a long time to cross or turn, before I am allowed to use the crosswalk or just the intersection, without a crosswalk! Given what my riding does for the Earth & All Living Beings & decreasing traffic, all automobiles should instantly have to come to a stop/LIGHTS TURN RED & wait for me!
Of course if we all had Scandinavian style whole roadway or at least completely protected & separated cycle lanes, than this would a much less of a problem.
I use myself as an specific example for all cyclist. Imagine all cyclist have the same problem.


Each stop is like another 100m travel. They soon add up. Approach sensors, anticipatory greens and green waves are worthwhile and done in the best countries.
“Each stop is like another 100m travel.” That is a joke right? There is no distance added, very little time added for pushing a button, for bicyclist. By the way, you have read that what I suggested was automatically, after activated, going from Green-Yellow-Red. Automobiles would have to have time to come to a stop. Going from Green to Red would be a safety issue for automobiles & bicyclists crossing.
No joke. It’s a fact of physics, explained in https://www.camcycle.org.uk/magazine/newsletter46/article9/
I was agreeing with you that the Green-Amber-Red sequence should be triggered by approach sensors. This is called “anticipatory greens” in the UK.
The other problem with beg buttons is that once they’re installed, it only takes one motoring supremacist to lengthen the delay and keep active travellers waiting so long that the light basically becomes irrelevant because there will be a gap where you can cross before the lights ever stop motorists. Nearly all crossings near me are configured that way. Only two sets ever change quicker. Another one is meant to but never does for me.
