An Information Network for Route Guidance and Travel Guidance Systemsby Clay Collier, IVHS Groups, Plymouth, United States,
Abstract: Automotive Route Guidance Systems are being marketed and tested around the world. These systems provide easy-to-follow, step-by-step instructions to guide a driver to any location in a metropolitan region, typically taking real-time traffic information into account in determining routes. The realization of some social benefits from IVHS do not arise directly from Route Guidance Systems, however, and in some cases may conflict with individual travel preferences. Some social benefits may result from reducing dependence on private automobile travel altogether, not merely optimizing individual trips. The delicate balance is achieved by producing the general social benefits without discouraging the commercial investment that is critical for IVHS to succeed. The thesis of this paper is that such a balance can be achieved only through the establishment of a widespread public/private travel information network that encompasses multi- and inter-modal traveler information. The information must be made available in private, commercial, and transit vehicles, at home, in hand, and at the office.
