COMPUTERS CONTROL CHANGEABLE MESSAGE SIGNS

The Wisconsin Department of Transportation is using its new changeable message signs in one of the most aggressive quick-response traffic information systems in the country. Each sign is numbered and equipped with a cellular telephone link. As state patrol troopers call in their central dispatcher, the dispatcher can instantly issue an advisory message to a nearby sign for display to approaching motorists. Wisconsin is among the first states to use these sophisticated signs on rural interstate construction zones where phone lines may not be readily accessible. At a 12-mile long construction zone on I-90 near Janesville, the signs are providing the high percentage of tourist traffic route options through the single lane bottlenecks.
