I asked this a week ago in the Traffic engineering forum, and got no response - is anyone here willing to take a crack at it?
How much volume can flaggers be expected to handle? I recall seeing 850 vph proposed as a cutoff for alternating one-way signal control, but I've never seen any studies about flaggers.
There would be a lot of variables - presence or absence of sideroads, experience level of the flaggers, length of the work zone, etc. Let's say it's a short work zone, without sideroads, and average flaggers.
