Description

This repo contains the code used to clean, process, and analyze the data used in "Measuring Racial and Ethnic Disparities in Traffic Enforcement with Large Scale Telematics Data." All figures and tables appearing in the paper were produced by knitting the main.Rmd R-markdown file.

Replication

Due to privacy concerns we are unable to release telematics data from Cambridge Mobile Telematics, which are used in main.Rmd. However, the TomTom telematics data included in this repo are sufficient to replicate our main results.

To facilitate replication, this repository uses the renv package to manage R package versioning.

First, from this directory, run

Rscript -e "renv::restore(rebuild = TRUE)"

to install the required packages. If installation fails, you may need to install the following additional libraries:

• udunits,
• GDAL.

Finally, knit the rep.Rmd R markdown file as follows:

Rscript -e "knitr::knit('rep.Rmd')"
