Use these scripts to reproduce the analysis contained in the paper Access to Secure Ballot Drop-off Locations in Texas authored by Alex Karner (UT-Austin) and Dana Rowangould (Univ. Vermont).

The scripts generate all required travel times, clean and prepare all demographic data, calculate required scores, and report results. Each is described below:

1. 01-transit-analysis.R: Use r5r to calculate travel times from every origin block group in Texas to the closest ballot drop-off location.
2. 02-auto-analysis.R: Process automobile travel times previously calculated using ESRI Streetmaps Premium.
3. 03-demographic-analysis.R: Retrieve relevant census data
4. 04-results.R: Generate figures and tables to include in the paper.
