This variant is intended for Check In/Check Out systems where every entry and exit of a vehicle is recorded. However, it is also possible to record entering and leaving stops, also in combination. Examples are ticketing systems where in metro or railroad stations, the entering and leaving of the stop areas is recorded, and in complementary surface transport (bus, streetcar) the entering and leaving of the vehicle is recorded.
Accordingly, the data may include information about multiple path legs. If access to the vehicles is controlled, the data collected will contain information about the line or even the individual trip. Access controls at bus stops contain location information only.
The information collected on the path legs in the vehicles is binding. During the plausibility check, only direct connections are checked that match the specifications. This means that if only the line is specified, all vehicle journeys of all line routes of the line are eligible. When specifying the line route only its vehicle journeys etc. down to the specification of the specific vehicle journey for which then no alternative is allowed. Thus, no shortest path searches are performed and the minimum walk time is not taken into account, since the data set is collected directly when the passenger boards the vehicle.
Shortest path searches are always performed for path legs that contain only location information (Plausibilization of e-ticket data collected at system boundaries).
