You can ask google about your next bus schedule by specifying your route name and direction.
Example: WS inbound, DCL inbound.
This is based on the schedule that was released by OCCT at https://www.occtransport.org/schedule and not the real-time bus location.
Ideal use of this app is when you are getting ready to travel, situations where before taking a bath to ask for the schedule and plan the speed that you want to get ready. From the library/gym ask for the schedule and plan accordingly to catch a bus.
