900 West (North Temple to 1700 South) One-Year-After Crash Analysis

A Simple Before-After Crash Study was performed for 900 West between North Temple St and 1700 South. Three years of before project crash data was compared to one year of after project crash data. The construction period for the project was July 1, 2017 – December 31, 2017. Crashes that occurred during the construction period are not included in the analysis since they likely do not represent typical roadway conditions.

Before and after years for the study are as follows:

“Year -3” = July 1, 2014 – June 30, 2015
“Year -2” = July 1, 2015 – June 30, 2016
“Year -1” = July 1, 2016 – June 30, 2017
“Year +1” = January 1, 2018 – December 31, 2018

The Crash Types graph above indicates that for Year +1, all crash types either decreased or remained about the same, as compared to the previous three years, except for rear-end crashes which show a pronounced increase. To better understand the principal causes of these crashes, rear-end crashes for all years were analyzed.
