The General Transit Feed Specification (GTFS) [1] is a standard de facto for public transportation schedules and related geographic information. This format allows developers to build applications quite easily.
GTFS defines a set of files and their content. These files are simple CVS files that can be edited using a text editor or a common spreadsheets application. Some files are mandatory while others are optional.
Matera municipality released bus timetables as opendata [2]. Unfortunately, these data are not in a machine readable format. The challenge is to translate [2] into GTFS.
We are going to focus only on required files at this stage, that is:
- agency.txt
- stops.txt
- routes.txt
- trips.txt
- stop_times.txt
- calendar.txt
We have a Google Spreadsheets [5] for this.
Moreover, we would like to create also shapes.txt file that shows how to draw bus routes on a map. In this case, we collect gps tracks using smartphones or other devices. Some people helped us to collect data for some lines. Collected tracks are stored in [3].
We use Trello [4] for coordinating our activities. If you are going to help, Trello is the first place you should visit.
We need help for:
- Collecting gps tracks
- Editing tracks with JOSM
- Filling up core GTFS files with Google Spreadsheet [5]
- Writing documentation/amending typos
Work in progress
- How to track routes with your smartphone
- How to simplify routes
- How to edit tracks with JOSM
- How to upload tracks on OSM
- How to create shapes.txt from gpx files
