For Integrated Transportation Management Systems (ITMS) to be a truly integrated system, and to move from a focus primarily on traffic management to a more global view of transportation management, consideration must be given to the inclusion of other modes and functions. These include toll facilities, bicycle and pedestrian systems, commercial vehicles and private operators, parking facilities, disaster response teams, railroads, and landside access to ferries, airports, ports, and railroads. The integration of these modes and functions into ITMS is not an easy process, however. Numerous technical and institutional issues will need to be addressed to help ensure that these systems are developed and operated with a multimodal focus. This resource paper is intended to help foster, enhance, and expand on the discussion of the components to be included in multimodal ITMS, potential issues and opportunities associated with this approach, and possible implementation strategies. As such, it builds on the experiences with existing transportation management systems, the previous ITMS Symposium, and the activities of other groups. It takes a fresh look, however, at the modes and functions necessary to help ensure the development and operation of multimodal ITMS to meet the complex transportation needs in metropolitan areas. To accomplish this objective, the paper is divided into four sections, following the introduction. The first section presents the concept of a multimodal ITMS and describes the various components to be included in such a system. The second section presents a discussion of potential technical and institutional issues that may emerge in planning, designing, funding, and operating multimodal ITMS. Opportunities for incorporating a multimodal focus into ITMS are also described. The third section outlines different implementation strategies that may be considered for multimodal ITMS. The approaches discussed provide for different levels of involvement, coordination, and control by the agencies and groups involved in multimodal ITMS. The concluding section gives a summary of the major topics covered and identifies areas for further research. Examples of current applications and suggestions for possible approaches are provided throughout the paper. |
