A bus schedule shows the times when buses are expected to arrive at each stop along a route. Schedules help riders plan their trips, knowing when to be at their stop. Service frequency varies—some busy routes run every few minutes during rush hour, while others may have hourly service in quieter areas or times. Schedules are published online, in apps, and at major stops. Real-time arrival information using GPS tracking increasingly supplements schedules, showing actual bus locations. Transit agencies must balance demand for frequent, reliable service against operating costs, making scheduling a key element of transit planning.
