Hyptbtr implementation.

Parameters

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

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

  • D_TIME (pandas.datetime) – departure time.

  • 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.

  • stop_out (dict) – key: stop-id (int), value: stop-cell id of key (int). Note: stop-cell id=-1 denotes cut stop.

  • trip_groups (dict) – key: tuple of all possible combinations of stop cell id,

  • value – set of trip ids belonging to the stop cell combination

  • 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

List of pareto-optimal arrival Timestamps

Return type

out (list)

Examples

>>> output = hyptbtr(36, 52, pd.to_datetime('2019-06-10 00:00:00'), 4, 1, 1, stop_out, trip_groups, routes_by_stop_dict, stops_dict, stoptimes_dict, footpath_dict, idx_by_route_stop_dict, trip_transfer_dict, trip_set)
>>> print(output)
