GTFS

Creating bundles

Unfortunately, we were not successful with building a OneBusAway transit data bundle for the full CTA GTFS feed and we had to prune to specific routes. Here is the command used to prune with GTFS Transformer CLI:

java -jar onebusaway-gtfs-transformer-cli-1.3.2-20130709.205351-10.jar \
    --transform='{"op":"retain","match":{"file":"routes.txt", "route_id":"6"}, \
    "retainBlocks":false}' \
    archives/chicago-transit-authority_20130320_0324.zip \
    pruned/pruneToRoute6_gtfs20130320

And this is the command to build the transit data bundle with Transit Data Federation Builder:

java -jar onebusaway-transit-data-federation-builder-1.1.10-withAllDependencies.jar \
    pruned/pruneToRoute6_gtfs20130320 bundles/pruneToRoute6_gtfs20130320
