Fork for own city

[janpio]

I am looking into forking this for my city (Berlin).

I found an equivalent to what you have in google_transit.zip (although I have to filter it down as it also contains busses, trams, regional trains, ...).

What about schedules/?

Anything else missing besides running the commands you listed in README?

PS: Nice project by the way!

Hi there! /schedules is actually generated by gtfs_json.py. You might need to modify the paths in that file a bit, but it shouldn't need to many changes!

(make sure to unzip your google_transit.zip file in the directory before running the script)

Thanks! Will do and let you know how it goes.

Finally got to it.

This is my data source: http://www.vbb.de/de/download/GTFS.zip Some information about it: https://transitfeeds.com/p/verkehrsverbund-berlin-brandenburg/213

generate_routes_json.py:

• 8 MB routing_graph.json
• 1 kb subway.json :(

I also had to edit line 178 to this:

    if not xfer['min_transfer_time'] == "":
        time = float(xfer['min_transfer_time'])
    else:
        time = float(0)

Seems some min_transfer_time are missing in my dataset.

gtfs_json.py:

• 4 Gig of RAM, needed to install 64bit python (Windows)

• schedules/transfers.js is 3.5Mb
• all the other files in schedules are 1kb :(

I would be happy with part of the data, but don't know how to filter the dataset locally: https://transitfeeds.com/p/verkehrsverbund-berlin-brandenburg/213/latest/routes?type=400

Any pointers or ideas to any of my issues?

Ok, found a way to filter/extract some stations: https://gis.stackexchange.com/a/219398/111548 http://developer.onebusaway.org/modules/onebusaway-gtfs-modules/current-SNAPSHOT/onebusaway-gtfs-transformer-cli.html

Generating the schedules still doesn't really work, but the other files look good.

Let's try if it can render something:

• rename subway.json to subway.js
• add subway = at the beginning of the file
• update map.js: let defaultStop = '127'; // times sq (line 33) and replace "127" with one of my stops

Whee I see something!

• Map seems to be rotated 15-20 degree counter clockwise

So I got it working for the default loading state: https://janpio.github.io/subway/

Compare this to Google Maps: https://www.google.de/maps/@52.5183954,13.4724959,10.56z/data=!5m1!1e2 (only the green lines are in the data set right now)

See my commit for the changes that were necessary: https://github.com/janpio/subway/commits/master And some notes and research at the end of the README: https://github.com/janpio/subway/commits

Now on to fix the schedule stuff...
