Abstract: A real-time directory access system provides the public with information of interest of an organization, and enabling mobile personal communication devices to access the organization's information of interest and to interactively communicate with the organization. This system includes an organization's central data server, a plurality of branch data servers for storing branch information of interest and for interactively communicating with mobile devices, a plurality of in-branch access points for distributing information of interest. The system also includes a plurality of mobile personal communication devices for receiving and displaying information of interest from access points and interactively communicating with branch data servers.

Abstract: An intelligent vehicle highway system collects and provides real-time traffic data to a vehicle traveling on a continental roadway network. A digitized continental roadway network has nodes interconnected by links that define a digitized representation of the continental roadway network. To enable intelligent data collection and navigation over large expanses of the continental network, which would otherwise be computationally onerous, the digitized continental roadway network is partitioned into a plurality of digitized roadway subnetworks. The onboard vehicle navigation device has a processor for executing an application that instantiates a subset of the digitized roadway subnetworks in a vicinity of a current position of the vehicle to collect and provide relevant real-time traffic data to the vehicle in a computationally efficient manner.
