Build Transfer Patterns¶

Builds structures related to transfer patterns

builders.build_transfer_patterns.initialize() → tuple[source]¶

Initialize variables for building transfer patterns file.

Returns: print line breaker G: Network graph of NETWORK NAME stops_list (list): CORES (int): Number of codes to be used WALKING_LIMIT (int): Maximum allowed walking time start_time: timestamp object USE_PARALlEL (int): 1 for parallel and 0 for serial MAX_TRANSFER (int): maximum transfer limit for which transfer patterns will be built. WALKING_FROM_SOURCE (int): 1 or 0. 1 indicates 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. GENERATE_LOGFILE (int): 1 to redirect and save a log file. Else 0 USE_TBTR (int): 1 to use TBTR for generating transfer patterns. 0 for RAPTOR CHANGE_TIME_SEC (int): change-time in seconds.
Return type: breaker (str)

builders.build_transfer_patterns.post_process(runtime, CORES, HUB_COUNT, NETWORK_NAME) → None[source]¶

Post process and print the statistics realted to transfer patterns.

Parameters

runtime (float) – total runtime in minutes
CORES (int) – Number of codes to be used
HUB_COUNT (int) – number of hub stops NETWORK_NAME (str): name of the network

Returns

None

builders.build_transfer_patterns.remove_older_files(NETWORK_NAME, HUB_COUNT) → None[source]¶

Creates a new (empty) directory for saving transfer patterns.

builders.build_transfer_patterns.run_raptor(SOURCE)[source]¶

Generate transfer patterns in parallel using RAPTOR. Transfer patterns are saved locally.

builders.build_transfer_patterns.run_tbtr(SOURCE) → None[source]¶

Generate transfer patterns in parallel using TBTR. Transfer patterns are saved locally.
