A propositional inventory is presented pertaining to definitions, cost, automation, and attitudes of transit managers, unions and taxicab companies. The proposition is considered that demand responsive transportation (DRT) will obtain an increasing share of the transportation market as public officials respond to the transit demands of multinucleated metropolitan areas. The cost of DRT and fixed-route transportation (FRT), the benefits of zonal increments, and the recommendation for critical path method of incremental development (with regard to equipment) are discussed. The demand for DRT is restricted by the inability of operators to supply an acceptable level of service. Automated scheduling and information processing can increase efficienty; a fully integrated DRT cannot be achieved without automation. Integrated DRT systems which link flexible-route and fixed-route transit are considered and it is pointed out that it is a mix of systems acting cooperatively, and not necessarily under single ownership, that adapts to demand. Computer systems are needed for the control and management of an integrated DRT system, but they lead to unforseeable complexities. It is noted that institutional attitudes rather than technical problems restrain expansion of DRT, and that taxi companies should be more actively involved as operators if integrated DRT is to expand. The successful projects in Ann Arbor, Michigan, Rochester, New York, the stalled program in Orange County, California, and the unsuccessful experiment in Santa Clara county are considered as illustrations.
