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.
Claims25
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.

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.

- 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.
