GTFSFilter

About

To filter gtfs files by a polygon. It's written in R and uses the gtfsTools library. We use it for OpenTrippPlanner

Prepare data

1. Copy the GTFS files you want to filter to this project and either name it de.gtfs.zip or change the path in gtfs_filter.R
2. Copy the polygon as GeoJson to this project or use the already existing. You can download GeoJSON polygons on this page. You may want tho change the path in gtfs_filter.R. By default it uses wohle BW.

Locally I recommend to use just KVV/Karlsruhe date. Too much data will need to mach memory. Use server for big data.
