Abstract

A commuter route selection system (10) includes a portable device (12) for receiving a travel time for at least one preselected commuter route and disseminating the travel time to a user and a central facility (14) for storing the at least one preselected commuter route and for obtaining current traffic information for the preselected commuter route. The central facility (14) transmits a current travel time for the preselected commuter route to the portable device (12).

Claims

1. A commuter route selection system comprising:

a portable device for receiving a travel time for at least one preselected commuter route and disseminating the travel time to a user; and

a central facility for storing the at least one preselected commuter route and for obtaining current traffic information for the at least one preselected commuter route, wherein the central facility transmits a current travel time for the at least one preselected commuter route to the portable device.

2. The system of claim 1, wherein the portable device receives and disseminates a travel time for each of a plurality of preselected commuter routes and wherein the central facility stores each of the plurality of preselected commuter routes and obtains current traffic information for each of the plurality of preselected commuter routes.

3. The system of claim 1, wherein the portable device includes a display for displaying the current travel time for the at least one preselected commuter route.

4. The system of claim 3, wherein the display further displays a representation, including a plurality of route segments, of the at least one preselected commuter route received from the central facility and wherein the each route segment is coded to indicate a commute time.

5. The system of claim 1, wherein the portable device includes an audio output source for broadcasting the travel time to the user.

6. The system of claim 1, wherein there are a plurality of portable devices each receiving a current travel time for each of a plurality of preselected commuter routes from the central facility.

7. The system of claim 1, wherein the portable device includes a global positioning system unit for transmitting a present position of the portable device to the central facility such that the central facility uses each present position to calculate at least a portion of the current travel information.

8. The system of claim 1, wherein the portable device further includes a user interface for the user to input a request for the current travel time and a transmitter for transmitting the request to the central facility and wherein the central facility transmits the current travel time upon receiving the request.

9. A commuter route selection system comprising:

a central facility for storing a plurality of preselected commuter routes for each of a plurality of users and for obtaining current traffic information for each preselected commuter route;

a plurality of portable devices wherein each portable device is designated for a particular user for receiving a current travel time for each preselected commuter route for the particular user and disseminating the current travel time to the particular user; and

wherein the central facility transmits the current travel time to one of the plurality of portable devices in response to a request from the portable device.

10. A commuter route selection system comprising:

a central facility for storing a plurality of preselected commuter routes for each of a plurality of users and for obtaining current traffic information for each preselected commuter route;

a plurality of portable devices wherein each portable device is designated for a particular user for receiving a current travel time for each preselected commuter route for the particular user and disseminating the current travel time to the particular user;

wherein the central facility transmits the current travel time to one of the plurality of portable devices in response to a request from the portable device; and

wherein each portable device includes a global positioning system unit for transmitting a present location to the central facility and wherein the central facility uses each present location for determining at least a portion of the current traffic information.
