MTA Bus Time, stylized as BusTime, is a Service Interface for Real Time Information, automatic vehicle location (AVL), and passenger information system provided by the Metropolitan Transportation Authority (MTA) of New York City for customers of its bus operations under the New York City Bus and MTA Bus Company brands. First tested in late 2010 and officially launched in early 2011, MTA Bus Time was installed in all MTA bus routes in New York City by 2014.
The software uses Global Positioning System (GPS) technology equipped in buses to relay real-time location information to passengers via internet-enabled devices (particularly smartphones), SMS messages, or countdown clocks installed at bus stops. Since 1996, the MTA had tried to install positioning technology for buses through numerous pilot programs, which were implemented in various stages.
