The Transportation Equity Act for the 21st Century, or TEA-21, enacted in 1998, following the Intermodal SurfaceTransportation Equity Act (ISTEA) of 1991, defines the “public” as “citizens, affected public agencies, representatives of transportation agency employees, freight shippers, private providers of transportation, representatives of users of public transit, providers of freight transportation services and other interested parties.” More recently the Federal Highway Administration (FHWA) has expanded this definition to include underrepresented groups “such as low income or minority households and the elderly”. In the last decade public involvement has been mandated for all metropolitan and statewide planning processes (TEA), and it …

The State requested a GIS-based route planning tool. More than 50 raster data layers were assembled within ArcView 3.2, encompassing a full spectrum of demographic, physical, and cultural features. These data layers were given a numerical rating using multicriteria decision making software and input from professionals from a variety of fields. The multicriteria decision making software then set the relative importance of these surface features as impediments or attractors, creating a travel-cost surface. This synthesis of technologies, combined in a tool termed AMIS (Analytic Minimum Impedance Surface), found the least-cost path to any point within the study area.
