This paper describes an innovative application of formal prioritization principles to intermodal planning. A priority system was constructed as part of the development of Oregon Department of Transportation (ODOT) Intermodal Management System. It is designed to help identify transportation system needs based on quantitative, facility type-specific performance measures; to rank the needs; and to prioritize projects for meeting the needs. In addition, the system provides an opportunity for sensitivity analysis to distinguish which assumptions or uncertainties significantly affect priorities from those that do not. This information can point the way to data collection efforts that are most effective in improving the allocation of investment resources. This work produced a practical and logically defensible system for supporting the ODOT planning process, and generated concepts and models of potential use for other aspects of transportation planning and programming. The priority system was tested through an application to 25 actual intermodal system needs and proposed projects. For example, the application compared projects to improve truck access to a railway yard, widen a roadway segment, build a railroad overcrossing, and add information kiosks at a passenger terminal. Following the system logic, needs were ranked based on the benefit that would result from eliminating those needs, and projects were ranked based on benefit-to-cost ratio. Topics addressed in the paper include principles of prioritization, methods of quantifying benefit, models for estimating performance for ten types of intermodal transportation facilities (connector and mainline roadways, bus stations, rail passenger stations, air passenger terminals, marine terminals, rail truck facilities, grain reload facilities, petroleum terminals, truck terminals, and air cargo facilities), ranking methodologies, and software implementation.
