The agency's "My Bus" system enables riders to text to find out when a bus is arriving at more than 19,000 stops.
All that's needed is a five-digit ID for their bus stop. Those are available online at njtransit.com.
Passengers text the five-digit ID to MyBus to receive the route and arrival times.
NJ Transit executive director James Weinstein says the service is part of an ongoing effort to use technology to improve access to travel information.
