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.
