Saskatchewan Department of Highways and Transportation (DHT) conducted a pilot study in 1989 to assess the benefits of utilizing a GIS to graphically illustrate and query the existing corporate databases. The success of this pilot study led to the full development and implementation of GIS for the Department. In August 1990, DHT initiated a planning study of the rural and suburban highways surrounding Saskatoon, throughout one of six highway districts of the Department. The study had two objectives: first, the study provided a regional highway system plan for the Saskatoon District. This was based upon the development of a travel database, and the calibration of a travel demand forecasting model. This paper describes the full-scale integration by the Department of GIS with a travel demand forecasting model. The finished product is a microcomputer based system capable of generating, distributing and assigning future traffic volumes to the existing or modified highway network. The system calculates level of service parameters, and displays input and output data on a digitized base map of the Saskatoon District.
