1. A traffic information system for determining and communicating a traffic anomaly to at least one receiving vehicle, said system comprising:
- a traffic information center configured to determine and transmit an alert to at least one receiving vehicle; and
at least one probe device communicatively coupled to the center, and configured to determine a current value of a traffic condition at a point during each of a plurality of trips, and store the current values in an on-board database, so as to build a history of condition values;
said at least one probe device being further configured to compare each current value to the history of condition values, so as to determine a condition discrepancy during each trip, and transmit a notification to the center, only when the discrepancy is greater than a pre-determined discrepancy threshold,said center being further configured to generate the alert based upon the notification.

Abstract
A system and method for determining and communicating a traffic anomaly at a point to at least one receiving vehicle includes a traffic information center and at least one probe device. Each probe device is configured to determine and store within an on-board database a current value of a condition at the point during each of a plurality of trips, so as to build a history of condition values. The probe device is further configured to compare the current value to the historic values during each trip, and selectively transmit notification of an anomalous value to the center.

18. A traffic information system for determining and communicating a traffic anomaly to a remote location, said system comprising:
-
at least one probe device configured to determine a current value of a condition at a point, during each of a plurality of trips, and store the current values in an on-board database, so as to build a history of condition values, said at least one probe device being further configured to compare the current value to the history of condition values, so as to determine a condition discrepancy during each trip, and transmit a notification to the remote location, only when the discrepancy is greater than a pre-determined discrepancy threshold; and a monitoring device located at the remote location, communicatively coupled to the probe device, and configured to generate a humanly perceptible signal upon receipt of the notification.

19. A traffic control system for communicating a traffic anomaly to at least one receiving vehicle upon a link, said system comprising:
-
a traffic information center including a map database presenting a plurality of pre-defined links; and at least one probe vehicle communicatively coupled to the center, and configured to determine a current value of a condition at a point, during each of a plurality of trips, and store the current values in an on-board database, so as to present a history of condition values, said at least one probe vehicle being further configured to compare the current value to the history of condition values, so as to determine a condition discrepancy during each trip, and transmit a notification to the center, only when the discrepancy is greater than a pre-determined discrepancy threshold, said center being further configured to generate an alert based upon the notification, to determine the position of the point upon the map database, and to transmit the alert to said at least one receiving vehicle, when said position is located within a predetermined area relative to the link. - View Dependent Claims (20, 21, 22, 23, 24)
