For many bus services, real time information is available online which shows when the bus will depart from the stop of your choice. When this real time information is not available, timetable information shows the time the bus is scheduled to depart the stop.
You can access this information through the YourNextBus website. Search for the specific stop, for example, the nearest stop to your business. This URL can then be saved for future use by bookmarking. You can also add this as a link on your website or intranet.
