Lovely Rita: Insights from Oakland Citation Data

Lovely Rita is set of tools for reading, cleaning, and saving parking parking citation datasets. The name pays homage to the song, Lovely-Rita, by the Beatles.

The project is a part of Oakland's Code for America brigade OpenOakland. You can read more about the project in this presentation.

With Lovely Rita, you can load historical parking citation data, clean the data (addresses and dates), geocode (turn addresses into geospatial coordinates), and save cleaned data to shapefiles for GIS analyses.

Check out our documentation for more detail.

Installation

It is good practice to use a virtual environment.

git clone https://github.com/openoakland/lovely-rita.git
cd lovely-rita
pip install -r requirements.txt
pip install . --user

Raw data format

Raw data should be provided in a .csv with the column names (in any order):

ticket_number
ticket_issue_date
ticket_issue_time
street
street_name
street_number
street_suffix
violation_external_code
violation_desc_long
state
city
badge_number
fine_amount

Command line interface

Several useful workflows can be run from the command line. Learn about the available workflows using lovelyrita --help. Learn about a specific workflow using lovelyrita <workflow> --help.

Python interface

There is also a python inferface if you want to dive deeper into the data. There are more involved examples in the notebooks folder.

Read in the data

from lovelyrita.data import read_data
citations = read_data(data_path)

Clean the data

Lovely Rita can also clean and parse addresses and dates.

from lovelyrita.data import read_data
from lovelyrita.clean import clean
citations = read_data(data_path)
citations = clean(citations)

Analyze the data

  1. Number of citations per zip code
  2. Time-series, number of citations
  3. Type of violation by zip code

Save the data

There is also support for storing the data to shapefiles

from lovelyrita.data import write_shapefile
write_shapefile(citations, 'my-shapefile.shp')
