This paper describes an approach used to implement a PC-based scheduling graphics system as part of a larger management information system installation at the Niagara Frontier Transportation Authority (NFTA) in Buffalo, NY. The implementation of the HASTUS computerized scheduling system at the NFTA included the integration of the PC-Graphics module into a multi-user hardware configuration. The approach designed for Buffalo uses advantages from both the single-user and multi-user approaches. It allows the full use of the PC-based graphics windows with fast response for the mouse-to-screen interface. At the same time, a single database exists on the multi-user machine. A potential drawback is the response time in transferring data to and from the PC.
