This tool illustrates the value of crash modification factors (CMFs) in the project development process and demonstrates the practical application of CMFs. The CMFs in Practice series includes five separate guides that identify opportunities to consider and quantify safety in specific activities, including:

1. Roadway Safety Management Processes.
2. Road Safety Audits.
3. Design Decisions and Exceptions.
4. Development and Analysis of Alternatives.
5. Value Engineering.

Each guide in the series includes a step-by-step demonstration of how CMFs can be applied in a specific activity, a case study to show real-world application of CMFs, discussion of potential challenges in applying CMFs, and opportunities to overcome those challenges. The series also includes reference documents that provide background information on CMFs and safety performance functions (SPFs).
