Abstract: There is provided a handheld device for navigating about a selected geographical zone. The handheld navigating device includes a processor circuit with a screen on which an image representative of a geographical map of a selected geographical zone is displayed. The geographical map of the selected geographical zone includes representations corresponding respectively with points of interest having locations and categories. The geographical map is configured so that (a) at least part of the representations corresponding respectively with points of interest are clustered within at least one viewing area, (b) the at least one viewing area is distinguished by a visible pattern having both a selected appearance and a first visual state that do not reveal the locations and the categories of the points of interest. The handheld navigation device includes a geographical position locating subsystem for determining when a selected relationship exists between the user and one or more of the points of interest.

Abstract: A computer-implemented system and method generate a representation of travel costs for an individual traveler. The method includes computing a fixed community cost component attributable to each traveler in a community, per time period, computing a fixed individual cost component for the individual traveler, per time period, and for each of a set of time periods, computing a variable individual cost component for the individual traveler. For each of the time periods in the set of time periods, the fixed community cost, fixed individual cost, and variable individual cost components are aggregated into an aggregated cost. A representation is generated for displaying the aggregated costs for the set of time periods to the individual traveler, in which the three cost components are identified.
