Penta’s WavWriter is an ADA-compliant voice and visual passenger information system includes redundant servers, IP based user workstations, and local transit station controllers. The system alerts passengers over public address displays, monitors, big boards, small kiosks, and smartphones of train arrivals, departures, and schedule information. Our software suite accepts real-time train information data and automatically processes that data into vital information for customers, riders, operators and users of any form of passenger transit.
