Build TBTR dict

Builds data structure for TBTR related algorithms

builders.build_TBTR_dict.algorithm1_parallel(route_details: tuple) → list

Collects all possible trip transfers.

Parameters

route_details (list) – tuple of format: (route id, list of trips)

Returns

list of trip-transfers format [(from trip id, from stop id, to strip id, to stop id)]

builders.build_TBTR_dict.algorithm2_parallel(trip_transfer_: list) → list

Removes trip transfers which cause U-turns.

Parameters

trip_transfer (list) – trip transfers. Format : [‘index’, ‘from_routeid’, ‘from_tid’, ‘to_routeid’, ‘to_tid’, ‘from_stop_index’, ‘to_stop_index’]

Returns

Returns the index if the trip-transfer is optimal. Else empty list

builders.build_TBTR_dict.algorithm3_parallel(trip_details: tuple) → list

Removes trip transfers that are not part of any optimal journey

Parameters

trip_details (tuple) – tuple of form: (route_id, trip_id, trip)

Returns

list of non-optimal trip transfers.

builders.build_TBTR_dict.initialize() → tuple

Takes the required inputs for building TBTR preprocessing

Returns

string CORES (int): Number of codes to be used change_time (int): change-time in seconds. GENERATE_LOGFILE (int): 1 to redirect and save a log file. Else 0 USE_PARALlEL (int): 1 for parallel and 0 for serial

Return type

breaker (str)
