Abstract: The Intermodal Surface Transportation Efficiency Act passed by Congress in 1991 requires transportation agencies to develop six management systems that will guide state and local official decision-making. Many transportation agencies are now trying to determine how these management systems should be developed. This paper describes a microcomputer Geographic Information System (GIS)-based transportation program management system developed for a county department of transportation (DOT) that serves as a prototype for an integrated transportation management system. The GIS platform used for this system was TransCAD. The system consists of several modules each focusing on one particular component of the DOT's functional responsibilities. These modules include pavement management, traffic engineering, accident analysis, and transportation/transit planning. The paper describes the basic characteristics of each module and how the GIS was implemented in each area. With regard to traffic engineering, the paper illustrates how a GIS can be used as a tool for traffic signal coordination.
