Why frequency is the service

How often a vehicle comes is the service a rider can actually use, not the line's existence.

When the purchase is complete, return to the original window. It will refresh.

From the opening

Frequency is how often a transit vehicle arrives on a route, usually talked about as the gap between trips. For the rider it is the service, because a line that exists on a map but comes rarely cannot be used without planning a life around a timetable. The opening covers the gap between vehicles is the product, a short gap forgives a miss, and rare service demands a timetable.

The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
