INTERMODAL APPLICATIONS OF ADVANCED TRAVELER INFORMATION SYSTEMS : THE CASE OF AIRPORT GROUND ACCESS

Advanced Traveler Information Systems (ATIS) are currently being deployed in metropolitan areas for both highway and transit systems and are being examined for their applicability to all phases of the longer distance trip between metropolitan areas. Work now underway at the I-95 Corridor Coalition is examining the needs of the traveler for longer distance trips by modes other than the private automobile. Work currently underway at the Transit Cooperative Research Program is examining a wide variety of strategies useful to the designer of public transportation services to airports, including the need to get information to the user about alternatives to the automobile trip. Based on the work at these two organizations, this paper reviews the application of elements of ATIS programs to aid the traveler in the provision of a multisegment public mode trip (i.e. a trip requiring several modes) which provides the user with an alternative to the automobile trip. The examples illustrate the technology available to improve the utilization of public modes to major airports
