The environment for statewide transportation planning continues to grow more complex. At the same time, continued innovation in personal computing capabilities is allowing transportation planners to link previously disparate databases and thus develop robust analysis routines that address a variety of issues within and between modes. The Georgia Department of Transportation's (GDOT's) Multimodal Transportation Planning Tool (MTPT) is one such tool for statewide planning that facilitates multimodal assessment of transportation needs and opportunities in rural and small urban areas. The MTPT is a comprehensive system and project-level planning tool that can be used to identify needs and project priorities for non-urbanized areas in Georgia. The MTPT integrates a series of analytical routines into a Geographic Information System platform, allowing an assessment of passenger travel on essentially all surface transportation modes. At the system level, the MTPT can assess various metrics of current and future operational and physical performance, and identify those modal elements that fail to meet threshold values or that have been previously identified as modal needs. At the project-level, the MTPT can perform a more detailed safety, operational, and physical analysis of roadway corridors, including those targeted for statewide bicycle routes. The analysis framework in the tool links multiple agency databases to provide planners, decision makers and the public with a consolidated picture of transportation deficiencies and needs for the state. The MTPT can produce results at various aggregation levels including individual corridors, cities, counties, and GDOT administrative districts. In a typical session, an MTPT user identifies the geographic area to analyze, identifies modes to analyze, enters any user-specified parameters, conducts baseline and sensitivity analyses, and displays the results. This paper provides an overview of MTPT development with special emphasis on agency databases and analysis routines that made the tool feasible. Customization and calibration efforts are also presented. Attention is paid to current use of the MTPT for preparing Georgia's Statewide Transportation Plan in order to highlight usefulness of the tool in a practical application.

The CD-ROM contains the proceedings of the sixth, seventh and eighth conferences. The eighth conference proceedings were published in October 2001.
