Executive Summary Report: GIS Maintenance and Resource Allocation Visualization;Final rept. 2 Jan 02-31 Dec 02

摘要

Highway systems throughout the United States are showing their age. Consequently, transportation agencies across the country are increasingly faced with the dilemma of allocating resources to new construction to increase capacity or allocating resources to maintain existing roadways. The allocation process includes economic safety, engineering and political concerns. Therefore, it is vital for planners and policymakers to view and understand multi-criteria decision models. Moreover, they must be able to effectively depict their decisions to stakeholders and constituents. The research project prototyped multi-criteria decision models, using geographic information systems (GIS) based on statistical analysis and data mining techniques. Although these techniques are effectively used in the private sector, their use is rare by transportation agencies to allocate resources. The project combined work by Alabama Department of Transportation staff and University of Alabama researchers to specify, design, build, test, and evaluate a multi-criteria visualization resource allocation support prototype system.
