Scheduling and dispatching a fleet of vehicles to respond to ongoing requests for transportation to and from various points in an urban area can be a complex proposition. Human controllers face an unmanageable number of scheduling possibilities. A strictly mainframe computer-based system would require elaborate computer algorithms, and high investment cost. This paper discusses the development of a low-cost interactive microcomputer color graphics system that displays vehicle and demand information and performs routine tasks while freeing the human dispatcher for creative decision-making. The development of this system was supported by UMTA Office of Methods and Support.
