This paper reports on the development of an in-house low-cost data-driven Transportation Geographic Information System (TGIS) for network flow simulation, highway planning and pavement management and evaluation. With the advent of the TGIS system, Alberta Transportation and Utilities has already achieved improved efficiencies and productivity for numerous conventional and innovative applications. This report briefly describes the applications of TGIS as an expert system in making decisions in areas of (1) transportation modelling and (2) infrastructure management. The TGIS system covers a wide area for applying powerful computer graphics which translate voluminous data into easily understood plots and easily understood plots and statistics for managerial decision making. It does not only serve as a tool for data management but also provides data for quick decision making. The TGIS system has therefore become a very powerful expert system tool for presenting information assisting in making decisions, and synthesizing of supporting a variety of new applications by embodying operations research models.
