GeoDecisions from the information technology industry has recently completed the first phase of the Decision Support Environment project for the Iowa Department of Transportation (DOT). GeoDecisions and its teaming partner, Bentley, developed a GeoData Library (GDL) that houses the department’s enterprise transportation data. The GDL leverages the processing services provided by Iowa DOT’s Linear Referencing System (LRS), a method to integrate various types of roadway features and roadway characteristics previously collected from different referencing systems.

Additionally, GeoDecisions designed, developed, and implemented two applications – the Coordinated Transportation Analysis and Management System (CTAMS) Web and CTAMS Analyst. The systems allow users to access the data in the GDL for viewing, reporting, decision support, and in-depth analysis. CTAMS Web is available via the Iowa DOT intranet and provides the entire department with browser-based access to analyses and reports to support decision making. CTAMS Analyst offers high-end analysis functions for experienced GIS users. The second phase of the project provides Iowa DOT with maintenance and enchancement support for the system’s major components – the GDL, CTAMS Web, and CTAMS Analyst.
