PTNA: news for Public Transport Network Analysis

Yay! I hope it goes well. @mcliquid, any and all feedback on this feature would help us improve it!

If any more information can be gleaned from the GTFS feed that would be useful for filtering, we can make that happen. For example, the Israel GTFS feed names the city of each bus stop. This is used to create a list of cities each route stops in.

Example can be seen here: https://ptna.openstreetmap.de/en/testcsv.php?network=IL-HA-Haifa

- catalog_number: '35030', city: 'זבולון,קרית אתא,רכסים', internal: 'yes'
30;bus;מק״ט: 35030 ([https://markav.net/line/35030/ מר קו]);קרית אתא - מרכז;;אגד;IL-MOT;28562

The ‘city’ hidden variable lists the 3 cities this route stops in: זבולון, קרית אתא, רכסים

DE-BW-bodo currently does not have any hidden variables. Hidden variables are only visible in the injection test page, not in the final CSV uploaded to the wiki.

If you have any more questions, feel free to ask.

@bergaufsee I think we will do DE-BE-VBB next. (Actually, @ToniE, do you think we can do it right now too?)
