Algorithms.TBTR.rtbtr.rtbtr(SOURCE: int, DESTINATION: int, d_time_groups, MAX_TRANSFER: int, WALKING_FROM_SOURCE: int, PRINT_ITINERARY: int, OPTIMIZED: int, routes_by_stop_dict: dict, stops_dict: dict, stoptimes_dict: dict, footpath_dict: dict, idx_by_route_stop_dict: dict, trip_transfer_dict: dict, trip_set: set) → list[source]
Parameters

  • SOURCE (int) – stop id of source stop.

  • DESTINATION (int) – stop id of destination stop.

  • d_time_groups (pandas.group) – all possible departures times from all stops.

  • MAX_TRANSFER (int) – maximum transfer limit.

  • WALKING_FROM_SOURCE (int) – 1 or 0. 1 means walking from SOURCE is allowed.

  • PRINT_ITINERARY (int) – 1 or 0. 1 means print complete path.

  • OPTIMIZED (int) – 1 or 0. 1 means collect trips and 0 means collect routes.

  • routes_by_stop_dict (dict) – preprocessed dict. Format {stop_id: [id of routes passing through stop]}.

  • stops_dict (dict) – preprocessed dict. Format {route_id: [ids of stops in the route]}.

  • stoptimes_dict (dict) – preprocessed dict. Format {route_id: [[trip_1], [trip_2]]}.

  • footpath_dict (dict) – preprocessed dict. Format {from_stop_id: [(to_stop_id, footpath_time)]}.

  • idx_by_route_stop_dict (dict) – preprocessed dict. Format {(route id, stop id): stop index in route}.

  • trip_transfer_dict (nested dict) – keys: id of trip we are transferring from, value: {stop number: list of tuples

  • form (of) –

  • trip_set (set) – set of trip ids from which trip-transfers are available.

Returns

out (list): list of trips required to cover all optimal journeys Format: [trip_id] elif OPTIMIZED==0:

out (list): list of routes required to cover all optimal journeys. Format: [route_id]

Return type

if OPTIMIZED==1

Examples

>>> output = rtbtr(36, 52, d_time_groups, 4, 1, 1, 0, routes_by_stop_dict, stops_dict, stoptimes_dict, footpath_dict, idx_by_route_stop_dict, trip_transfer_dict, trip_set)
>>> print(output)
