Yep, it’s made it to North America. Just no cool light-up bollards.
I’ve been too pre-occupied of late to look up what the MUTCD says about colored pavement markings, so I’m not sure where red fits. In the general red/yellow/green of MUTCD signage, red works – you, as the driver, are prohibited from driving in the transit lane.
Assuming that’s OK and that’s the rationale, what do we do with the green-painted bike lanes that are popping up? I think the initial idea was that “green = ecosustainabliltyconservationpuppiesandallthingsgood” but in the MUTCD world, green is used for “indicated movements permitted, direction guidance” … which doesn’t really fit.
