It looks like Garner Station Blvd at Lennox Place is the closest stop. You can use the Capital Area Transit site to plan trips via bus http://www.raleighnc.gov/services/content/PWksTransit/Articles/CapitalAreaTransit.html
Or you can use maps.google.com and select bus directions
Both Cities has bus services that can accomodate handicapped aned thy also have a special van that can be called andarrange formore personal service if needed, depending on your needs. My wife is legally blind, so I am more familiar with Durham.
