The Public Address Customer Information Screen system is a major component of the Metropolitan Transportation Authority's effort to substantially upgrade customer communications across its entire network and marks an important milestone in the effort to provide subway customers with up-to-date travel information employing 21st Century technology.
The PA/CIS screen provides train arrival messages in audio and video. The messages indicate when the next two trains are due to arrive at the station and their destinations. Aside from train arrivals, the system also allows NYC Transit to provide both audio and visual messages to customers, keeping them fully informed about service delays or emergency situations. PA/CIS is being rolled out incrementally with 152 stations on the IRT numbered lines operational by the first quarter of 2011. PA/CIS was first introduced along the Canarsie L line in January 2007.
The information distributed through the PA/CIS system originates from NYC Transit's Rail Control Center. From the RCC, customer service agents will be able to provide subway customers with service status and other information either as audio only, visual only or as synchronized audio and visual information. The system includes signs and speakers that are located on the platforms and in the fare control areas prior to entering the station. PA/CIS will be installed in additional IRT stations in Brooklyn, the Bronx and Manhattan throughout the city in the coming months.
