Implementation problems limit the contribution of new methods to transportation planning practice. This case study documents the introduction of geographic information systems (GIS) to a large employer's trip reduction program. This paper's comparative approach outlines six organization conditions for a successful match of client expectations and GIS performance, describes the Arizona State University (ASU) trip reduction effort, and uses the six conditions to evaluate this application. When technical and administrative problems prevented a quick contribution to measurable trip reduction, GIS effort lost employer support.
