Abstract:
1. A traffic control system for updating and communicating at least one condition to at least one receiving vehicle upon a thoroughfare link, wherein the condition presents link specific data, said system comprising: a traffic information center configured to determine and store a first value of the condition; and at least one probe vehicle communicatively coupled to the center, and configured to determine a probed value of the condition; said center being configured to transmit to said at least one probe vehicle the first value of the condition, said at least one probe vehicle being further configured to compare the first and probed values of the condition, so as to determine a condition discrepancy, and transmit the probed value to the center, where the discrepancy is greater than a pre-determined discrepancy threshold, said center being further configured to modify the first value of the condition upon receipt of the probed value from said at least one probe vehicle, and transmit the modified first value to said at least one receiving vehicle, wherein each probe vehicle is configured to determine and transmit to the center a current time, location, and heading, and said first value of the condition is based on the current time, location and heading, wherein the condition is the anticipated travel speed of a vehicle traveling upon the thoroughfare link, each probe vehicle is configured to transmit a destination input to the center, and the center includes a map database, and is configured to determine an average travel speed for a plurality of thoroughfare links within the database, the current location of the probe vehicle, a recommended route based on the current location and destination input, and the estimated total travel time of the route.
