                    [-d DISTANCE] [-m MODE] [-c CONCURRENT]
                    [ID [ID ...]]

• JSONFILE file containing transit stop ids and locations (see sample.json)
• GTFSDIR folder containing GTFS dataset referenced in JSONFILE
• PBFFILE OpenStreetMap PBF file of geography
• OUTFILE output geoJSON file
• DISTANCE maximum extent of walkshed
• MODE transit mode for annotating geoJSON
• CONCURRENT number of processors to use in importing PBF file (default: 2)
• ID route ids to filter for inclusion
