  • Abstract:
    The past year has seen the soft release of Iowa's Potential for Crash Reduction site. This site is how we display our Safety Performance Functions. As of August 31, 2021, the site includes information for intersections only. Segmental data is being crunched and is expected to be soft released in calendar year 2021. This exciting news is all due to the organization behind the Iowa HSIP. It's all part of our commitment to implementing a more data-informed approach for identifying locations and potential countermeasures for safety improvements. The Safety Analysis Incorporation (SAI) group, with representatives from various offices across the DOT, continues to oversee the development of tools and processes to advance the consideration of safety at all stages of project development. Other efforts overseen by the SAI group include: calibration of the Highway Safety Manual (HSM) safety performance functions (SPFs) to Iowa conditions, publication of an Iowa-specific list of crash modification factors (CMFs), development of a suite of HSM spreadsheet tools to evaluate project impacts and alternatives, and a brand new Safety Analysis Guide to aide designers and planners in applying these safety analysis tools. Additionally, a consultant has been hired and work has begun on developing an intersection configuration evaluation (ICE) policy and process.
