ssim2gtfs converts IATA SSIM flight schedule data into a GTFS zip containing trips, stops, stop times and calendars.
ssim2gtfs requires node 10.x or above
ssim2gtfs is a CLI tool that can be installed via NPM:
npm install -g ssim2gtfs
It can be run by specifying the input and output files as CLI arguments:
ssim2gtfs flights.ssim gtfs.zip
Or using unix pipes:
cat flights.ssim | ssim2gtfs > gtfs.zip
The GTFS does not support many of the fields in the SSIM standard so there is a lot of information that is not retained.
- An extended route type of 1100 (air service) is used
- All timezones are converted to UTC
- Stop data is derived from ourairports.com
- Agency data is derived from openflights.org/
Issues and PRs are very welcome. To get the project set up run
git clone firstname.lastname@example.org:planarnetwork/ssim2gtfs npm install --dev npm test
