TransNet Generator

TransNet Generator is a Python library for generating transport networks from GTFS data. The library provides a convenient and efficient way to generate transport network graphs from one or multiple GTFS directories to a graph in Pajek or GML format, which can be used for network analysis and visualization.

Installation

To install TransNet Generator, you can use pip:

pip install transnet-generator

Usage

To use TransNet Generator, you can import the transnet_generator module and use the generate_graph function:

from transnet_generator import generate_graph

input_GTFS = ["path/to/gtfs/directory1", "path/to/gtfs/directory2"]
output_path = "path/to/output/graph"

generate_graph(input_GTFS, output_path)

The generate_graph function takes two required arguments:

input_GTFS - A list containing the paths to the directories containing the GTFS files.
output_path - The path to the output graph file.

Supported Output Formats

TransNet Generator supports the following output formats:

Pajek (.net)
GML (.gml)

To specify the output format, simply pass the desired format as a string to the output_format parameter of the generate_graph function.

Examples

Here's an example of how to generate a graph file in Pajek format from one GTFS directory:

from transnet_generator import generate_graph

input_GTFS = ["path/to/gtfs/directory"]
output_path = "path/to/output/graph.net"

generate_graph(input_GTFS, output_path, format="pajek")

Here's an example of how to generate a graph file in GML format from three GTFS directories:

from transnet_generator import generate_graph

input_GTFS = ["path/to/gtfs/directory1", "path/to/gtfs/directory2", "path/to/gtfs/directory3"]
output_path = "path/to/output/graph.gml"

generate_graph(input_GTFS, output_path, format="gml")
