Here we have traffic controllers or "Lolly pop folk" with "stop /go" lolly pop signs at each end (at a safe distance). The law states that traffic & pedestrians must obey (like police) directions. If the controllers breach their responsability/duty they can face a $10 000 fine individually and/or $100 000 fine for the company.
Even then stupidity can prevail. I had a stop sign back in late 90's when a lady almost ran me over (I literally had to jump clear of her car into the middle of the road).
She stopped exactly where the felling was in progress. The guy in charge ran over & asked what she was doing. She responded with something like "Was i supposed to stop back there?" The giant dangerous gum tree was about to fall right where she stopped. It was on a wide rural nature strip and onto the road was the only "safe" place to drop it.
