Abstract
The present invention is directed to a portable system for automatic data acquisition and processing of traffic information in real-time. The system incorporates a plurality of sensors operatively positioned upstream of a work zone or roadway incident with each of the sensors being adapted to detect current traffic conditions, at least one variable message device positioned upstream of the work zone or roadway incident, a plurality of remote station controllers, each operatively connected to the plurality of sensors and the variable message device, and a central system controller located within remote communication range of the remote station controllers, wherein the central system controller and the plurality of remote station controllers are capable of remotely communicating with one another. Each of the sensors is adapted to output traffic condition data to its corresponding remote station controller. The corresponding remote station controllers then transmit the traffic condition data to the central system controller. The central system controller automatically generates traffic advisory data based on the traffic condition data and transmits the traffic advisory data to the rem…
