Crash Analysis

Top 200 Safety Improvement Candidate Locations (SICL) – Intersections

The Iowa Department of Transportation's Office of Traffic and Safety has updated a list of the top 200 intersection safety improvement candidate locations (SICL) in Iowa. This document lists all 200 sites with accompanying information used to develop the candidate list, including crashes by severity and volumes. The table below has links to information prepared for each site to aid in the analysis of the candidate sites. This table is sortable by each column and searchable by keywords within the city, county, and SICL intersections locations columns simultaneously.

To develop this list, all crashes in Iowa are used to determine an initial cut of intersections that meet the criteria of at least one crash. The intersections identified are then listed according to the number of crashes, the severity of the crashes, and the rate at which crashes occur. To read more details regarding Iowa's SICL, see Iowa SICL method.
