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.

Abstract: A system for testing and evaluating driver situational awareness incorporates a device for displaying road and traffic images to a subject being tested, road and traffic image data for simulating operation of a vehicle to be outputted on the display device, instruction data to be outputted at least on the display device, input devices for inputting response data from the test subject in response to road and traffic image data generated on the display means, and a control device for controlling the operation of the system. The control device incorporates a vision test component for conducting a vision test of the subject and a driving reaction test component for conducting a driving reaction test of the subject.

Abstract: A communication system includes a digital network and an audio network such as a telephone system. An audio network server communicates with client work stations in the digital network and with the telephones in the telephone system. The audio network server stores, and plays back, digital representations of voice objects from, and to, a telephone handset. An instruction set accessible from the digital network controls operation of the audio network server and thus the telephone system to record and play back audio information stored on the audio server. The communication system may also include a caching capability to temporarily store compound documents or component objects in a media presentation server.

Abstract: A communication system includes a digital network and an audio network such as a telephone system. The digital network includes a digital network server that communicates with client work stations in the digital network, and the telephone system includes a telephone system server that communicates with the telephones in the telephone system. Either the digital network or the telephone network server includes a memory that stores digital representations of voice objects received from the telephone handset. The digital network server includes a digital network server instruction set that operates the telephone system server to associate stored audio information received over the audio network with digital information of the digital network.
