That way! Which way?

My hometown just finished building a mile of bike lanes. The project looks great. With one oddity in the brand new lane markings…

The person on the bicycle and arrow have obvious meanings. A few yards/meters up the path (just visible on the left) is a symbol I’ve never seen before, which appears to be an alternative arrowhead, pointing in the direction of travel. Seems redundant, but OK.

But then, another few yards/meters ahead (visible in the middle) are three triangles facing the other direction!?

I’ve noticed similar “backwards” triangles this year on streets in London and Mauritius. Always on one-way streets, seemingly pointing opposite the direction of travel. Seemingly trying to denote “do not enter” with the flat side of the triangle as a virtual barrier. Turns out my interpretation was wrong, that those triangles are denoting that there is a yield ahead. https://mutcd.fhwa.dot.gov/htm/2003r1/part3/part3b2.htm

No matter the interpretation, I’m curious who thought triangles on the pavement pointing toward oncoming traffic was a good idea? Any I’m curious how many hundreds of people must have approved these to make them an international standard?

Am I the only person here to notice that the emperor has no clothes?

I learned how to point with my finger before I learned how to write. I could draw recognizable arrows before I could write legibly. I’ll bet more than half of the people who see these three little triangles will think the bike lane runs toward the camera.

I doubt this will lead to serious injuries, and thus I’m not going to spend time petitioning to remove those misleading triangles. But this is the first time I’ve seen those backwards triangles in view of both arrows and forward triangles, and that made me sufficiently curious to lookup the standard and to share.
