Ducklite is correct, our schedules are very dynamic. Depending on our current demand, and other conditions, our dispatches have the flexibility to change. Busses will run in 5-18 minute intervals, on average, depending on demand and location.
They will give you when you arrive a transportation guide that will tell you where the busses or boats go and how to get to locations that may require switching somewhere (you should look at those or ask question to assure you don't head to the bus stop when the transportation to where you are going is by boat). They also tell you generally that busses run every 15 to 20 minutes -- but during rush times they have a lot of manuevering going on to pick up as quickly as possible where the need is and you can see them quicker.
