Transportation Planning, in the past and currently for the most part, has been driven by mobility needs as measured by the level-of-service (LOS) criterion in the peak hour. What is even more unfortunate in the current planning process is that coordination and integration of modes are still not seriously addressed by the respective modal transportation authorities. The creation of the Louisiana Transportation Trust Fund in 1989 and the federal Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) mandates that a statewide, systemwide balanced and integrated transportation plan be developed that addresses the following key areas: (i) passenger movements on multimodal systems; (ii) freight movements on systems; (ii) freight movements on multimodal systems, among other tasks by year 1995. The specific objectives of this paper, part of a larger $1.2 million ISTEA research study, are: (i) the development of a conceptual flow diagram of a statewide intermodal transportation plan for passenger movements that covers the entire state, including border crossings, access to ports, airports, and intermodal transportation facilities, and at the same time addresses the needs and/or connectivity of both non-metropolitan and metropolitan areas; (ii) provide a detailed description of each phase of the conceptual flow diagram in order to allow for quantitative model developments; and (iii) identify how the proposed methodology may be applied to the state of Louisiana (area) 50,820 square miles (population 4,219,973 (1990) with all the main modes of transportation.
