gtfs-realtime-tools

A set of utilities for interacting with GTFS-realtime feeds.

Set up

• Install Python 3 and pip3 (sudo apt install python3-pip).

• Install the protobuf compiler (also can be downloaded here):

  sudo apt install protobuf-compiler
  

  I think brew install protobuf might work on Mac.

  Run protoc --version to confirm that version 3 or higher is installed.

• Install the protobuf Python library:

  sudo pip3 install protobuf
  

Building

Run the build script:

./build.py

Tools

• gtfsrt2text.sh: Renders a GTFS-RT feed file in a human-readable text format for debugging.
• get_timestamp.py: Extracts the timestamp field of a GTFS-RT feed file.
• format_timestamp.py: Converts a POSIX timestamp (like the output of get_timestamp.py) to a human-readable format.
