First Claim
Patent Images
1. A method for disseminating traffic information to users, comprising the steps of:
- maintaining at least one database comprising;
a plurality of trip description structures;
information regarding conditions of travel associated with at least one of the trip description structures in view of current information;
respective trip data corresponding to at least one trip for each of a plurality of users, the trip data being communicated by the plurality of users and including, for each user;
at least one geographic identification, at least one critical time selected from the group consisting of a start time for the at least one trip, an arrival time for the at least one trip, a desired start time for the at least one trip, and a day of the week when the at least one trip is to be undertaken, and at least one communication specification selected by that user, processing the trip data, at a predetermined time relative to the critical time and responsive to the conditions of travel, to identify at least one situation relating to the trip data; and
contacting at least one user at a second time relative to the critical time, responsive to the situation and in accordance with the communication specification.

Abstract
Automatic personal advisories relating to traffic conditions are provided at pre-specified times via avenues of communication specified by the users. Use is made of a map database to generate routes and various types of advisories. Traffic conditions may be evaluated by comparing current speed data against nominal speed data.

8. The method of claim 1, wherein the critical time is stored as a range of times.
-
9. The method of claim 1, wherein the trip data includes more than one critical time and a respective communication specification for each critical time.
-
10. A data processing device comprising:
-
at least one memory for embodying at least one database in a form readable by the data processing device, the database comprising;
a plurality of trip description structures;
information regarding conditions of travel associated with at least one of the trip description structures in view of current information;
respective trip data corresponding to at least one trip for each of a plurality of users, the trip data being communicated by the plurality of users and including, for each user;
at least one geographic identification, at least one critical time selected from the group consisting of a start time for the at least one trip, an arrival time for the at least one trip, a desired start time for the at least one trip, and a day of the week when the at least one trip is to be undertaken, and at least one communication specification selected by that user, at least one processor adapted to perform the following operations processing the trip data, at a predetermined time relative to the critical time and responsive to the conditions of travel, to identify at least one situation relating to the trip data; and
causing at least one user to be contacted at a second time relative to the critical time, responsive to the situation and in accordance with the communication specification;
at least one communications portal for effecting contact with users and receiving the information regarding the conditions of travel. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
the trip data further comprises identification of appropriate ones of the trip description structures; - and
processing the trip data comprises checking the appropriate ones of the trip description structures against the conditions of travel.
-
-
15. The device of claim 10, wherein the processing includes comparing current speed with nominal speed, for appropriate ones of the trip description structures.
