ptatohed, thanks for the quiz. To clarify, is this intersection has four legs and ADT represent each leg? Thank you

MUTCD 2009, page 688 & 689, figure 6H-28. Sidewalk detour. The minimum is 36 inches

I second John with B. Thanks for posting this though

I found the answer by just look it up. Thought to share this questions for practice purposes. hopefully your answer will match mine. The minimum width of a pedestrian detour, for ADA compliance, is _ inches a) 12 b) 24 c) 36 d) 48

This question is written in a good way. The answers are pretty much distractors. like John said, it is great to get more familiar with MUTCD.

Sorry, I used MUTCD 2009, Chapter 2, page 108

I used Table 2C-4. Guidelines for Advance Placement of Warning Signs With posted speed of 50 mph and advisory speed of 40 mph The advanced placement distance is 100' Blg23, Thanks for posting this problem

Blg23, I like your thought process. I guess the test is approaching fast and no point of waiting since your answer is detailed. So yeah, u r correct. It is C

1.R,f,e are given, plug them to superelevation equation to get V 2.the new speed is =2V 3.Now the given are the new v and e only. find the new f from the AASHTO chart(using the new speed) 4. Plug them again to the superelevation equation to get the new R

A curve of radius 340 feet, side friction factor, fs = 0.16, and super-elevation of 8% is located at a section of an existing rural highway, which restricts the safe speed at this section of the highway to 50 percent of the design speed. This drastic reduction of safe speed resulted in a high...

Awesome. I really did not see that it is only the first volume until you mentioned it. I have looked at the references list while ago. Thanks for pointing that out.

Me too, the HSM is big. I haven't decided if I am gonna buy it or not.

Yes, difenatley this one is going to be in my afternoon binder.

I would take a guess for B) 0.88

John, Glad that you brought it up. I had to think about it for a little while. I got the same answer as Ptatohed, it is C Honestly, it took me more than 6 mins :suicide1:
