Abstract
The study has two aspects: (1) judgement of frequencies offered, planned or potentially viable for regular public bus services other than local town routes; and (2) prediction of effects any alteration on frequency of service, scheduled trip time, and routing, will have on passenger volumes. Frequencies will be judged against either actually measured or potentially expected passenger volumes. Aim is a normative system in which the passenger volume is the decisive factor for the frequency to be offered on the route under consideration.
