"Being a flagger used to be a job." I doubt the guy in the second video could handle that job. Maybe that is why the robot was invented.
They still use flaggers around here for short duration work. For longer duration work they'll set up a system like this, but it's just a set of temporary stop lights. They've been around for quite a while. I'm not sure what the advantage would be of having a physical moving flag versus the normal red, yellow, green lights that we're all used to. Maybe people not waiting and running the lights?
Mindblowing how much those guys & gals get paid. Probably because it is a boring job in all weathers and odd hours.
hey fools still drive around RR crossing arms so what makes anyone think they will respect a flag on an arm.
There is a bridge being reconstructed about 30 miles from here, has had the road cut to a single lane for over 2 years now. I have no idea why it should take so long to add 2 lanes to a 90 ft long bridge with the portable traffic lights at either end of the construction site situated over a mile apert. Again, no apparent reason for that distance being so great either, other than that may have been the closest distance they could put them so you couldn't see the other end, The lights are pressure cell and timer activated, defaulted to red both ways. Sometimes it might take as long as 8 minutes to change to green and no traffic has exited from the other direction. People drive through the red all the time figuring there will be no oncoming traffic. It gets really comical watching someone try to back up a half a mile
