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 FARS and GES/CRSS data back to 2011 with just one line of code. The result is a full, rich dataset ready for mapping, modeling, and other downstream analysis. Helper functions are also provided to produce common counts and comparisons.
You can install the latest version of rfars from GitHub with:
or the CRAN stable release with:
Then load rfars and some helpful packages:
The get_fars() and get_gescrss() are the primary functions of the rfars package. These functions either download and process data files directly from NHTSA’s FTP Site, or pull the prepared file stored on your local machine. They take the functions 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, 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 specifices the directory, and cache names the file (be sure to include the .rds file extension).
Here we get one year of FARS data for Virginia:
myFARS <- get_fars(years = 2022, states = "VA", proceed = TRUE)
#> ✓ 2022 data downloaded
#> Preparing raw data files...
#> ✓ Accident file processed
#> ✓ Vehicle file processed
#> ✓ Person file processed
#> ✓ Weather file(s) processed
#> ✓ Crash risk factors file processed
#> ✓ Vehicle-level files processed
#> ✓ PBtype file processed
#> ✓ SafetyEq file processed
#> ✓ Person-level files processed
#> ✓ Flat file constructed
#> ✓ Multi_acc file constructed
#> ✓ Multi_veh file constructed
#> ✓ Multi_per file constructed
#> ✓ SOE file constructed
#> ✓ Prepared files saved in C:/Users/s87ja/AppData/Local/Temp/RtmpOI3o4P/FARS data/prepd/2022
#> ✓ Codebook file saved in C:/Users/s87ja/AppData/Local/Temp/RtmpOI3o4P/FARS data/prepd/We could have saved that file locally with:
Note that you can assign and save this data with one function call.
We could similarly get one year of CRSS data for the south (MD, DE, DC, WV, VA, KY, TN, NC, SC, GA, FL, AL, MS, LA, AR, OK, TX):
myCRSS <- get_gescrss(years = 2022, regions = "s", proceed = TRUE)
myCRSS <- get_gescrss(years = 2022, regions = "s", proceed = TRUE, dir = getwd(), cache = "myCRSS.rds")The data returned by get_fars() and get_gescrss() adhere to the same structure: a list with six tibbles: flat, multi_acc, multi_veh, multi_per, events, and codebook. FARS and GES/CRSS share many but not all data elements. See the FARS Analytical User’s Manual and CRSS Analytical User’s Manual for more information.
The following section decribes the results from get_fars() but largely applies to get_gescrss() as well.
The flat tibble contains all variables for which there is just one value per crash (“accident”), vehicle, or person (e.g., intersection type, travel speed, age). Each row 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.

Each tibble 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 top name-value pairs of each tibble are shown below.

The codebook tibble provides a searchable codebook for the data, useful if you know what concept you’re looking for but not the variable that describes it. The rfars package includes a codebook for FARS and GESCRSS (rfars::fars_codebook and rfars::gescrss_codebook). These tables span 2011-2022 whereas the codebook object returned from get_fars() and get_gescrss() only include the specified years. See the vignette for more information.
