Service and route builder
Operators build what they sell on a map and a calendar rather than in a form, and see the shape of it before committing.
A service is a place, a duration and a set of rules about when it can run. The builder puts the first two on a map and a calendar, so an operator sees the distance, the travel time and the gap between two departures while they are setting them, instead of finding out from a customer complaint. Multi-leg routes carry their via points, and each leg keeps its own duration.
