fasttrips.FastTrips

class fasttrips.FastTrips(input_network_archive, input_demand_dir, input_weights, run_config, output_dir, input_functions=None, logname_append='', appendLog=False)

Bases: object

This is the model itself. Should be simple and run pieces and store the big data structures.

__init__(input_network_archive, input_demand_dir, input_weights, run_config, output_dir, input_functions=None, logname_append='', appendLog=False)

Constructor.

Reads configuration and input files from input_network_dir. Writes output files to output_dir, including log files.

Parameters:

• input_network_dir (string) – Location of network csv files to read
• input_demand_dir (string) – Location of demand csv files to read
• input_weights (string) – Location of pathweight file
• run_config (string) – Location of run configuraiton file.
• output_dir (string) – Location to write output and log files.
• logname_append (string) – Modifier for info and debug log filenames. So workers can write their own logs.
• appendLog (bool) – Append to info and debug logs? When FastTrips assignment iterations (to handle capacity bumps), we’d like to append rather than overwrite.

Methods

__init__(input_network_archive, …[, …])	Constructor.
read_configuration()	Read the fast-trips assignment and path-finding configuration
read_input_files()	Reads in the input network and demand files and initializes the relevant data structures.
run_assignment(output_dir)

Attributes

DEBUG_LOG	Debug log filename.
INFO_LOG	Info log filename.

read_configuration()

Read the fast-trips assignment and path-finding configuration

read_input_files()
