There are many ways to access Grand River Transit (GRT) real-time passenger information:
These applications provide information on predicted vehicle departure times so riders can get a better idea of when their bus will be leaving.
Real-time uses GPS satellite technology to track buses and provide their approximate location. Once the vehicle is located the system then predicts when the bus will depart future stops. Factors such as scheduled time, vehicle speed and distance help provide this information.
While GRT expects most predictions to be reasonably accurate, the technology is complex and relies on multiple systems, on and off the bus to work together. Because of this complexity, riders may occasionally receive inaccurate information when one system fails to communicate with the others. In some instances, if the technology cannot make an accurate prediction, it will show a scheduled departure time (~ on PID signs, * on text messaging). The mobile app shows both scheduled and real-time departure times.
Many of GRT's routes currently have detours, due to the numerous construction projects around the region, and some routes have multiple detours in effect. Real-time information is affected by detours as buses go off route and times adjust accordingly. As construction and detours end, and schedules become more accurate, so will the real-time information.
A rider should still arrive at their stop at least 5 minutes before the predicted or scheduled departure time. The closer the bus is to a stop the more accurate the prediction is likely to be. If you have made an early inquiry, recheck closer to the actual time to verify the bus departure time. Departure times can change due to influences such as traffic delays or the travel speed of the bus.
Technology is not always perfect, but real-time helps our riders manage their time more efficiently and avoid waiting for their bus longer than they need to.
