EVALUATING DEMAND-RESPONSIVE TRANSPORTATION SYSTEMS. PANEL DISCUSSION

In the panel discussion following the presentation of papers on the evaluation of demand-responsive transportation (DRT) systems, comments were invited on the evaluation process. Experience in Washington, D.C. leads one to the view that for the same fixed of dollars, it is possible to provide a much higher level of service by making adjustment in the mix of the service. In the evaluation of DRT as a mode in comparison to other modes, factors considered are the incremental costs of ridership productivity of one mode against another mode under the same circumstances. Taxicabs are identified as a form of DRT and the comment is made that in the industry, measurement is made on a vehicle-per-mile basis whereas most disucssions at the conference centered on a vehicle-per-hour measurements. The need is also indicated for a vehicle designed for the handicapped, elderly and children. The importance is emphasized of the study and discussion of DRT system failures as an aid to the better understanding of these systems. It is noted that the study of other transit modes is important as a means to determine under what conditions DRT is an effective strategy. DRT is seen as a means of transportation uniquely suited to the aged, the handicapped, and the young.
