dvb 3.0.0

An unofficial Python module for Dresden's public transport system (VVO/DVB)

dvbpy

An unofficial Python module for querying Dresden's public transport system (VVO/DVB).

Want something like this for another language? Look here.

pip install dvb

from dvb import Client

client = Client(user_agent="my-app/1.0 ([e-mail])")

All API access goes through a Client instance, which requires a user_agent string identifying your project and providing contact details.

Find stops

client.find("Helmholtzstraße")

[
    Stop(id='33000742', name='Helmholtzstraße', city='', coords=Coords(lat=51.03, lng=13.73)),
    Stop(id='36030083', name='Helmholtzstr', city='Chemnitz', coords=Coords(lat=50.83, lng=12.93)),
    ...
]

Monitor a stop

client.monitor("Helmholtzstraße", limit=2)

[
    Departure(
        id='voe:11003: :H:j26',
        line='3',
        direction='Wilder Mann',
        scheduled=datetime(2025, 2, 22, 14, 41),
        real_time=datetime(2025, 2, 22, 14, 43, 50),
        state='Delayed',
        platform=Platform(name='1', type='Platform'),
        mode='Tram',
        occupancy='ManySeats',
    ),
    ...
]

Stop names are automatically resolved to IDs. You can also pass a numeric stop ID directly.

Plan a route

client.route("Helmholtzstraße", "Postplatz")

[
    Route(
        duration=11,
        interchanges=0,
        price='2,30',
        fare_zones='TZ 10 (Dresden)',
        cancelled=False,
        legs=[
            PartialRoute(
                duration=11,
                line='3',
                mode='Tram',
                direction='Btf Trachenberge',
                stops=[...],
            )
        ],
        session_id='367417461:efa4',
    ),
    ...
]

Use the session_id to paginate with client.earlier_later().

Map pins

Search for stops, POIs, and other points of interest within a bounding box.

client.pins(51.04, 13.70, 51.05, 13.72, pin_types=("Stop", "Platform"))

[
    Pin(id='33000028', name='Hauptbahnhof', city='Dresden', coords=Coords(...), type='Stop'),
    Pin(id='pf:1234', name='Hauptbahnhof Gleis 3', city='Dresden', coords=Coords(...), type='Platform'),
    ...
]

Lines at a stop

client.lines("33000742")

[
    Line(name='3', mode='Tram', directions=['Dresden Wilder Mann', 'Dresden Coschütz']),
    Line(name='66', mode='CityBus', directions=['Dresden Lockwitz']),
    ...
]

Route changes

client.route_changes()

[
    RouteChange(
        id='511595',
        title='Dresden - Mengsstraße, Vollsperrung',
        description='<p>...</p>',
        type='Scheduled',
        validity_periods=[ValidityPeriod(begin=..., end=...)],
        lines=['428296'],
    ),
    ...
]

Trip details

Get all stops for a specific departure (using the ID and time from a monitor response).

departure = client.monitor("Helmholtzstraße")[0]
client.trip_details(trip_id=departure.id, time=departure.scheduled, stop_id="33000742")

Reverse geocoding

client.address(51.04373, 13.70320)

Stop(id='33000144', name='Tharandter Straße', city='Dresden', coords=Coords(...))

Raw responses

All methods accept raw=True to get the unprocessed API response as a dict:

client.monitor("Helmholtzstraße", raw=True)
# Returns the raw JSON dict from the WebAPI

Error handling

from dvb import Client, APIError, ConnectionError

client = Client(user_agent="my-app/1.0 ([e-mail])")

try:
    client.monitor("Helmholtzstraße")
except ConnectionError:
    print("Network error or timeout")
except APIError:
    print("API returned an error")

Migrating from 2.x

dvb 3.0 introduces a Client class that requires a user_agent string. This helps the DVB/VVO identify API consumers and provides them with a way to reach out if needed.

• All functions have moved from dvb.function() to client.function() on a Client instance
• import dvb + dvb.monitor(...) → from dvb import Client + Client(user_agent="...").monitor(...)
• All method signatures remain the same

Migrating from 1.x

dvb 2.0 was a complete rewrite with breaking changes:

• All functions return frozen dataclasses instead of dicts/lists
• Functions raise APIError/ConnectionError instead of printing errors and returning None
• Migrated from legacy widget/EFA endpoints to the VVO WebAPI
• Removed poi_coords() (use find()), interchange_prediction(), city/eduroam/deparr parameters
• route() uses arrival=True/False instead of deparr="arr"/"dep", pins() uses pin_types=("Stop",) instead of pintypes="stop"
• Dropped numpy
• Requires Python >= 3.10
