Multi-modal traveler information system

摘要

A system and method for disseminating information concerning, for example, conditions affecting travel routes personalizes information in accordance with individual users or customers by building filters for attributes of the information from attributes of interest to each user, such as nodes of a travel route, which are registered with the system by the user or customer. The information is filtered by the filters constructed from the attributes to form a list of user identifications of users that have registered an attribute of interest which is included in the information provided to the system. Messages are retrieved from storage and communicated to users in accordance with the list of user identifications either automatically over one or more communication media also registered by each user or on a call-in inquiry basis. In the latter case and for modification or additions to registered user information and attributes of interest, the system and method provide for an active automated dialog with the user. Messages may include user-specified nomenclature for attributes or collections thereof.
