Describes available tools--studies, conferences, courses, reports, data, and quantitative models--that can help planners and policymakers respond to the requirements of the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) and the Clean Air Act Amendments of 1990 (CAAA). This report is presented in three major sections: Categorized Listings - technical assistance products sorted by principal subject category; Resource Centers - a list of DOT-sponsored sources of information and assistance on intermodal transportation; and Indices - by title, by lead agency, and by product.

This document identifies intermodal technical assistance activities originating within the U.S. Department of Transportation (DOT) which should be of use to metropolitan planning organizations (MPOs) and State and local planners in fulfilling their responsibilities under the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) and the Clean Air Act Amendments of 1990 (CAAA). The areas of intermodal technical assistance activity are: air quality analysis; citizen/industry participation; congestion management; economic analysis; environmental and social impact analysis; geographic information systems; intermodal facilities planning; intermodal freight transportation; intermodal systems -- planning and management; metropolitan and statewide planning activities; resource centers; transportation statistics; travel demand forecasting; and travel demand management.

This report documents and presents the results of a study of institutional barriers to intermodal transportation policies and planning. Stakeholder interviews, a literature review and a national survey of 421 transit agencies, MPOs, and state DOTs were utilized to identify 13 organizational, interjurisdictional, and resource barriers to intermodal planning. Findings of the study suggest that building community support, adequate funding, education, and leadership commitment are the primary driving forces that can improve intermodal planning practices. Structure, procedure, and leadership provide the decision-making context for intermodal planning, that is, they enable (or restrict) the regional or local decision-making process. Ten context-shaping recommendations are offered. Action planning sessions held in Albuquerque, New Mexico; Austin, Texas; and Queens, New York indicated that a number of attributes can enhance the local intermodal planning process.
