marta-python

Python library for accessing MARTA real-time API

Testing

# Install tox
pip install tox
# Run tests
tox

Installing

python setup.py install

Using

The MARTA Python library expects your API key to be stored in the MARTA_API_KEY environment variable:

On Windows:

set MARTA_API_KEY=<your_api_key_here>

On Mac/Linux:

export MARTA_API_KEY=<your_api_key_here>

Optionally, you can also set the cache timeout (default 30 seconds):

Windows:

set MARTA_CACHE_EXPIRE=15

Mac/Linux:

export MARTA_CACHE_EXPIRE=15

There are two primary API wrapper functions, get_buses() and get_trains(). Each method takes keyword arguments to filter results.

from marta.api import get_buses, get_trains

# Get all buses
buses = get_buses()

# Get buses by route
buses = get_buses(route=1)

# Get buses by route and stop_id
buses = get_buses(route=1, stop_id=900800)

# Get buses by route and vehicle_id
buses = get_buses(route=1, bus_id=1405)

# Get buses by route and timepoint
buses = get_buses(route=1, timepoint="West End Station")

# Get buses by route, stop_id and vehicle_id
buses = get_buses(route=1, stop_id=900800, bus_id=1405)

# Get all trains
trains = get_trains()

# Get trains by line
trains = get_trains(line='red')

# Get trains by station
trains = get_trains(station='Midtown Station')

# Get trains by destination
trains = get_trains(destination='Doraville')

# Get trains by line, station, and destination
trains = get_trains(line='blue', station='Five Points Station', destination='Indian Creek')

# Get trains by line, station, and direction
trains = get_trains(line='gold', station='Five Points Station', direction='north')

Results

The library includes very basic objects to represent Trains and Buses. Below are dictionary representations of each.

The get_buses() and get_trains() functions return lists of Bus and Train objects, respectively.
