USING GIS TO SELECT MODEL ZONE CENTROIDS
Conventional four-step urban transportation modeling system processes determine zone centroid locations via a subjective manual procedure. This paper, which appears in a compendium of conference papers, describes a methodology for deriving the zone centroid locations by employing a geographic information system (GIS). Some preliminary test results of this methodology are presented, revealing that the proposed method is capable of deriving centroid locations that better reflect the land use and the street patterns within individual traffic analysis zones. Several important considerations to the development of an operational system using GIS are reported in this paper.
