Each year the Kentucky Transportation Center publishes Analysis of Traffic Crash Data in Kentucky, a report that reviews state-level crash data from the previous five years. This report summarizes crash data for 2017 through 2021. In addition to presenting a review of crash data, the report also contains safety performance functions (SPFs) for nine roadway types. Because SPFs were derived using 2017-2021 data, the models predict crashes for a five-year period. Users must adjust the model by adding a coefficient of 1/5 to models to avoid overestimating crashes by a factor of five.
