If you are looking for guidance documents, I would start with the NACTO Urban Bikeway Design Guide and the Urban Street Design Guide. You can explore that site to find references to peer-reviewed journal articles on many aspects of non-motorized transportation. There is also the CROW out of the Netherlands, considered one of the first and best bike traffic guidance documents. I hope this helps!
