dvbpy
An unofficial python module giving you a few options to query a collection of publicly accessible API methods for Dresden's public transport system.
Want something like this for another language, look no further
The documentation is located here.
Get dvbpy from PyPi :)
pip install dvbAnd then just import it.
import dvbMonitor a single stop
Monitor a single stop to see every bus or tram leaving this stop after the specified time offset.
import dvb
stop = 'Helmholtzstraße'
time_offset = 0 # how many minutes in the future, 0 for now
num_results = 2
city = 'Dresden'
dvb.monitor(stop, time_offset, num_results, city)[{
'line': '85',
'direction': 'Striesen',
'arrival': 5
},
{
'line': '85',
'direction': 'Löbtau Süd',
'arrival': 7
}]You can also call monitor() without city, num_results or
time_offset. City will default to Dresden.
Find routes
Query the server for possible routes from one stop to another. Returns multiple possible trips, the bus-/tramlines to be taken, the single stops, their arrival and departure times and their GPS coordinates.
import dvb
import time
origin = 'Zellescher Weg'
city_origin = 'Dresden'
destination = 'Postplatz'
city_destination = 'Dresden'
time = int(time.time()) # a unix timestamp is wanted here
deparr = 'dep' # set to 'arr' for arrival time, 'dep' for departure time
dvb.route(origin, destination, city_origin, city_destination, time, deparr){
'trips': [{
'interchange': 0,
'nodes': [{
'line': '11',
'mode': 'Straßenbahn',
'direction': 'Dresden Bühlau Ullersdorfer Platz',
'path': [
[13.745754, 51.02816],
[13.745848, 51.028393],
...
],
'departure': {
'time': '18:01',
'stop': 'Zellescher Weg',
'coords': '13745754,51028160'
},
'arrival': {
'time': '18:14',
'stop': 'Postplatz',
'coords': '13733717,51050544'
}
}],
'duration': '00:13',
'departure': '18:01',
'arrival': '18:14'
},
...
}],
'origin': 'Dresden, Zellescher Weg',
'destination': 'Dresden, Postplatz'
}Everything besides origin and destination is optional and only needs to be included if necessary. City for origin and destination defaults to Dresden, time to now and is handled as the departure time.
The path property contains a list consisting of all the coordinates describing the path of this node. Useful for example if you want to draw it on a map.
If you use recommendations for interchanges, each of the nodes (except
the last one)in every trip will have a recommendation field. The
field will tell where you should enter this route to get an optimal
interchange experience. This is of course only if there are any
interchanges. The positions are 0 for front, 1 for middle and
2 for back. If there are no recommendations available None is
returned.
Find stops by name
Search for a single stop in the network of the DVB.
import dvb
dvb.find('zellesch')[{
'name': 'Zellescher Weg',
'city': 'Dresden',
'coords': [51.028366, 13.745847]
}]The fields city and coords are optional as they are not
available for every stop. So don't forget to check for their existence
first.
[stop for stop in dvb.find('Post') if 'city' in stop if stop['city'] == 'Dresden']Find other POIs with coordinates
Search for all kinds of POIs inside a given square.
import dvb
southwest_lat = 51.04120
southwest_lng = 13.70106
northeast_lat = 51.04615
northeast_lng = 13.71368
pintypes = 'stop'
# can be poi, platform, rentabike, ticketmachine, parkandride, carsharing or stop
dvb.pins(southwest_lat, southwest_lng, northeast_lat, northeast_lng, pintypes)pintypes defaults to 'stop' if no other input is given.

]Look up coordinates for POI
Find the coordinates for a given POI id.
import dvb
dvb.poi_coords(33000755){'lat': 51.018745307424005, 'lng': 13.758700156062707}Address for coordinates - WIP
Look up the address for a given set of coordinates.
import dvb
lat = 51.04373
lng = 13.70320
dvb.address(lat, lng){
'city': u'Dresden',
'address': u'Kesselsdorfer Straße 1'
}Other stuff
Stop names in queries are very forgiving. As long as the server sees it as a unique hit, it'll work. 'Helmholtzstraße' finds the same data as 'helmholtzstrasse', 'Nürnberger Platz' = 'nuernbergerplatz' etc.
One last note, be sure not to run whatever it is you're building from
inside the network of the TU Dresden. Calls to dvb.route() and
dvb.find() will time out. This is unfortunately expected behavior as
API calls from these IP ranges are blocked.
