A traffic management system |
摘要 |
A method and system for managing traffic via a plurality of traffic signs positioned sequentially along a stretch of roadway. Each traffic sign in the plurality of traffic signs is capable of displaying more than one different traffic message. The method comprises receiving at a first traffic sign in the plurality of traffic signs a wireless control signal indicative that the plurality of traffic signs are to display a new message, and then causing each traffic sign in the plurality of traffic signs to display a new traffic message. The new traffic messages displayed by the plurality of traffic signs provide information relating to a roadway condition downstream of at least the front-most traffic sign in the plurality of traffic signs.
