Abstract:
1. A traffic information system adapted for use by a mobile probe device spaced from a plurality of remotely traveling vehicles, and for updating at least one traffic condition and transmitting the traffic condition to at least one receiving entity, said system comprising: a traffic information center configured to store a first value of the traffic condition; and at least one mobile probe device communicatively coupled to the center, including at least one exterior sensor configured to concurrently detect remote vehicle conditions for each of said plurality of remotely traveling vehicles including the current time, location, speed, and heading of each of said plurality of remote vehicles, configured to determine at the device a probed value of the traffic condition based in part on the detected remote vehicle conditions, and transmit the probed value to the center, wherein the probed value is based on the average speed of remote vehicles having generally congruent headings; said center being communicatively coupled to said at least one probe device and said at least one receiving entity, and further configured to modify the first value of the traffic condition upon receipt of the probed value from said at least one probe device, and transmit the modified first value to said at least one receiving entity.
