Abstract
The development of the annual and multi-year transportation program in the United States is an example of a complex process with multiple decision-making activities at national, state, and local governmental agency levels. Transportation program development decisions are dynamic and interdisciplinary and involve considerable tradeoffs in financial, safety, and political contexts; state transportation agencies are developing spatial data warehouse infrastructures using geographic information system (GIS) technologies to address these decision needs. This article presents a conceptual model for the development of spatially enabled E-service intelligence products for state and local agency transportation program development and a hypothetical example of intelligence products for a transportation safety program.
