Hopefully this is a good idea as I think I will continue to keep getting questions that I need some insight on so I figured I would try and build it into a single thread and just keep adding to it and hopefully getting answers from other members.
I wish i could edit posts, unsure how/when that unlocks, but it would let me strike through answered questions or always update the OP with my newest ones. For now, we will just have to work vertically.
1) Is there an errata for the Goswami All-in-One Civil Exam Guide 3rd edition?
I haven't covered a ton of sections yet, but I keep finding errors or odd things that just seem completely out of place especially when it comes to working an example or problem in the book.
Just to show a couple examples of what I mean with my most recent findings...
1a) Problem 403-002: Are they looking this up in the 5th edition of the green book?
Table 403.6 on pg. 824 of Goswami claims to reference the 6th edition and results in an extremely different answer from the solution.
Otherwise is the table actually referencing the 5th edition and is miss-marked?
I currently don't have a green book yet so I can't check the exhibit it calls out in the solution, I am getting the 6th edition though.
1b) Example 406.2: They give a shoulder width, show the value of 2.4 for f(lc), but then just skip it and use 0 when calculating FFS.
1c) Example 406.3: In the chapter they mention typically use 1 for f(p), but use 0.85 if it is recreational, but then in the solution they decide to use 0.9 out of nowhere.
Are more values possible in other references or is this just semi-arbitrary?
2) What exactly is the difference between freeways and multi-lane highways?
I haven't dug into the multi-lane highway chapter yet, but can tell it will have different calculations for FFS and such so I need to know how/when to use one on the exam.
I would think freeways are a bit faster speeds, but there is some overlap for LOS like say 60mph.
3) I couldn't tell from the NCEES topics, but is it safe to skip the book's section on freeway ramps?
I am leaning towards yes, but figured I'd be safe with another opinion.
I think that's it for tonight, I will start keeping track of my questions and adding them here as I already skipped over a few thought from the past week or so.
Thanks for any help you can provide.
