This discussion of the important elements in the evaluation of a demand-responsive transportation (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. Decisions on whether to provide DRT service, who is to operate the service, the quality of service, and the financing of the operation will all be resolved at the local level. Users benefit either from the new service allowing them to take advantage of urban activities previously unavailable (induced demand) or from the new service being preferred to the one previously used. Nonusers are affected in a number of ways through externalties (air pollution, congestion, etc.) associated with the system. A basic decision is whether the operator of the service should be public or private transit based or taxi based. There may be significant negative impacts on other transportation services which must be recognized. The impact of DRT on other businesses and activities will be such that positive benefits will accrue to the activities previously poorly served by transportation and decreasing benefits associated with previously well-served activities. Research and operation experience indicate that more productive operations can be provided at higher demand densities; to achieve the higher demand density, however, requires subsidy.
