Among public transit and for-hire modes, fixed-route bus and rail are most effective in maintaining high ridership in high density areas such as urban centers. The cost effectiveness of fixed-route transit, however, depends on close proximity to the passenger's trip origin and destination, and diminishes rapidly as density decreases. Taxis, on the other hand, provide door-to-door service but at a premium price. Most taxi service, however, is congregated in high density urban areas where there is a higher pool of potential customers. Thus, taxis are expensive to use and hard to hail in low-density suburban areas. Conventional dial-a-ride provides a level of service and cost between
fixed-route transit and taxi, but service is only available to a small segment of the traveling population, namely the elderly and handicapped. Autonomous dial-a-ride transit (ADART) is a modernized version of dial-a-ride transit that provides service for the general population and offer a level of service, quality and cost somewhere between fixed-route bus and taxi. Compared to conventional dial-a-ride, however, ADART costs less to operate.
