ssim2gtfs

ssim2gtfs converts IATA SSIM flight schedule data into a GTFS zip containing trips, stops, stop times and calendars.

Usage

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

Notes

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/
