Hi!
Can anyone recommend a good book on this subject.
Horizontal aligment design, vertical aligment design, superelevation, parking places...
I found few good topics on the internet but I would like to buy a good book.
Thank you.
What are you trying to do? Learn the subject? Design a road? The Green Book is the bible for design, but it is not going to go very in-depth with teaching the actual subjects.
AnaAnt here is the FHWA link. This is where you can find some information. You may also take a look at your State DOT as they may have some additional information for geometric design.
If you have previous knowledge you will be fine...I was not sure of your level of experience. It's not really a "textbook" that will teach the subject, but if you have some background you will be fine.
