The goal of rfars is to facilitate transportation safety
analysis by simplifying the process of extracting data from official
crash databases. The National Highway
Traffic Safety Administration collects and publishes a census of
fatal crashes in the Fatality
Analysis Reporting System and a sample of fatal and non-fatal
crashes in the Crash
Report Sampling System (an evolution of the General
Estimates System). The Fatality
and Injury Reporting System Tool allows users to query these
databases, and can produce simple tables and graphs. This suffices for
simple analysis, but often leaves researchers wanting more. Digging any
deeper, however, involves a time-consuming process of downloading annual
ZIP files and attempting to stitch them together - after first combing
through immense data dictionaries to determine the required variables
and table names.
rfars allows users to download the last 10+ years of
FARS and GES/CRSS data with just one line of code. The result is a full,
rich dataset ready for mapping, modeling, and other downstream analysis.
Codebooks with variable definitions and value labels support an informed
analysis of the data (see
vignette("Searchable Codebooks", package = "rfars") for
more information). Helper functions are also provided to produce common
counts and comparisons.
You can install the latest version of rfars from GitHub with:
# install.packages("devtools")
devtools::install_github("s87jackson/rfars")or the CRAN stable release with:
install.packages("rfars")Then load rfars and some helpful packages:
library(rfars)
library(dplyr)The get_fars() and get_gescrss() are the
primary functions of the rfars package. These functions
download and process data files directly from NHTSA’s
FTP Site, or pull the prepared data stored on your local machine, or
(as of Version 2.0) pull the prepared data from Zenodo. The data files
hosted on Zenodo are stable, have DOIs, and replicate the data that
would be produced by get_fars() and
get_gescrss(), but in a fraction of the time.
get_fars() and get_gescrss() take the
parameters years and states (FARS) or
regions (GES/CRSS). As the source data files follow an
annual structure, years determines how many file sets are
downloaded or loaded, and states/regions
filters the resulting dataset. Downloading and processing these files
can take several minutes. Before downloading, rfars will
inform you that it’s about to download files and asks your permission to
do so. To skip this dialog, set proceed = TRUE. You can use
the dir and cache parameters to save an RDS
file to your local machine. The dir parameter specifies the
directory, and cache names the file (be sure to include the
.rds file extension).
Executing the code below will download the prepared FARS and GES/CRSS databases for 2014-2023.
myFARS <- get_fars(proceed = TRUE)
myCRSS <- get_gescrss(proceed = TRUE)get_fars() and get_gescrss() return a list
with six dataframes: flat, multi_acc,
multi_veh, multi_per, events, and
codebook.
The tables below show records for randomly selected crashes to illustrate the content and structure of the data. The tables are transposed for readability.
Each row in the flat dataframe corresponds to a person
involved in a crash. As there may be multiple people and/or vehicles
involved in one crash, some variable-values are repeated within a crash
or vehicle. Each crash is uniquely identified with id,
which is a combination of year and st_case.
Note that st_case is not unique across years, for example,
st_case 510001 will appear in each year. The
id variable attempts to avoid this issue. The GES/CRSS data
includes a weight variable that indicates how many crashes
each row represents.

The multi_ dataframes contain those variables for which
there may be a varying number of values for any entity (e.g., driver
impairments, vehicle events, weather conditions at time of crash). Each
dataframe has the requisite data elements corresponding to the entity:
multi_acc includes st_case and
year, multi_veh adds veh_no
(vehicle number), and multi_per adds per_no
(person number).

The codebook dataframe provides a searchable codebook
for the data, useful if you know what concept you’re looking for but not
the variable that describes it. rfars also includes
pre-loaded codebooks for FARS and GESCRSS
(rfars::fars_codebook and
rfars::gescrss_codebook). See
vignette('Searchable Codebooks', package = 'rfars') for
more information.
See vignette("Counts", package = "rfars") for
information on the pre-loaded annual_counts dataframe and
the counts() and compare_counts() functions.
Also see vignette("Alcohol Counts", package = "rfars") for
details on how BAC values are imputed and reported in Traffic Safety
Facts.
