Const. work zone S L reductions / recast
Const. work zone S L reductions / recast
(OP)
Okay, what I would really like to see is "actual" instances of use of WZ speed reductions. Anything ranging from expressway to two-lane (one-lane flagger TCP) facilities would be great.
Please no manual, policy, or organizational rhetoric.
You actually employed the reduction(s), and the good or bad of what transpired.
Input on the "actual results" of use of advisory speed plaques would be great as well.
And as is the usual case (of maintenance type work), the zones are not usually designed; they are existing facilities where standard TCP's are utilized with the addition of other measures to enhance the specific needs of the situation.
Thanks

For smaller jobs, e.g single carriageways, the length of the site is limited and the requirement to have sufficient working width for the workforce tends to narrow the traffiked lane enough that specific speed reduction measures are not needed.
I'm surprised you do not 'design' for roadworks in the US. I know you didn't want a manual, but try a Web search for 'Chapter 8' of the 'Traffic Signs Manual' to see how we have to do it this side of the pond.
