JOURNEY describes public transport vehicle's run on a given ROUTE through the city. Typically the run occurs at the same time on multiple days during a week. For example a certain JOURNEY on given ROUTE could start 10:00 AM on Mondays, Tuesdays, Wednesdays, Thursdays and Fridays. DAY TYPE, attached to a JOURNEY, classifies the conditions on which kind of days the JOURNEY occurs. Conditions can be week day names, but other kind of conditions can apply too (such as "busy day" or "all weekdays"). DAY TYPE EXCEPTION provides mechanism to temporarily deviate from conditions imposed by a DAY TYPE. For example if a JOURNEY would occur on all weekdays, public holidays could be modeled as DAY TYPE EXCEPTIONS. In other words we could say "This JOURNEY runs on every week day except 21.5.2014, because this day is Labor Day". | JOURNEY describes public transport vehicle's run on a given ROUTE through the city.

On a given time on a given DAY TYPE or a given ROUTE, the JOURNEY stops on certain STOP POINTS from where passengers can board or alight the vehicle. A CALL groups together the STOP POINT where the vehicle stops, and the time when the vehicle stops on that STOP POINT. Since the vehicle stops multiple times during a JOURNEY, a CALL also contains the order of the stop. | On a given time on a given DAY TYPE or a given ROUTE, the JOURNEY stops on certain STOP POINTS from where passengers can board or alight the vehicle. A CALL groups together the STOP POINT where the vehicle stops, and the time when the vehicle stops on that STOP POINT. Since the vehicle stops multiple times during a JOURNEY, a CALL also contains the order of the stop. CALLs on a certain JOURNEY follow a JOURNEY PATTERN. JOURNEY PATTERN is in essence a sequence of STOP POINTS on which the JOURNEY stops. In other words: ROUTE describes the vehicle's path through road network, and a JOURNEY PATTERN "overlays" it with a sequence of STOP POINTs. Consider a ROUTE as continuous drawn line and STOP POINTs as drawn circles on top of the line. STOP POINTs must follow the drawn line since those have to be on the vehicle's route. Single ROUTE can, however, have multiple JOURNEY PATTERNs: for example one for express line (which skips some of the stops) and one for the normal line which stops on every STOP POINT. | ||
