STV was hired by the New York City Department of Transportation to develop Real Time Passenger Information (RTPI) signs for select bus stops, from conceptual design through prototype evaluation. The RTPI signs utilize existing GPS tracking technology called MTA Bus Time, which provides riders with wait-time information for city buses and projects this data onto an easy-to-see LED display.

The RTPI sign prototypes are both line-powered and solar-powered. The latter signs are capable of gathering enough energy to power the signs 24 hours a day, seven days a week. The RTPI pilot program consists of two solar-powered signs that were installed at bus stops on Staten Island and one line-powered RTPI sign in Manhattan.
