Abstract
This discussion of the important elements in the evaluation of a DRT system, focuses on the groups of individuals who are potentially affected by implementation of a service, and the type and degree of impact. The broad categories of affected groups are identified as users of DRT services; non-users of DRT; operators of DRT; operators of other transportation services, and managers of other business and activity centers in the area. It is recognized that evaluation is and must remain primarily a local issue.
