My favourite roundabout between the main part of Bognor town & villages Flansham, Felpham & Elmer as far as I can remember. That is 3 areas or settlements, the others are Aldwick, Rose Green, Pagham, Bersted, and I guess Bognor Regis main area is the 8th settlement or ancient town that makes up the whole of Bognor Regis.
