I'm reading Microsoft's white paper Round-Based Public Transit Routing (the RAPTOR algorithm). In this algorithm, there are some definitions that I don't understand:About trip:trip represents a sequence of stops a specific vehicle (train, bus,  subway, . . . ) visits along a lineAbout route:Each route consists of the trips that share the same sequence of  stops.So, if I understand, trip means a bus route and a route is collection of trips to make a path? If my guess is true, why does it state:Typically there are more routes than tripsAnd if a route is just a collection of trips, how can I build all routes?
