Are you conducting a safety effectiveness study of a particular treatment, countermeasure, strategy or a combination of these? By developing a crash modification factor (CMF) from your research, you can provide valuable data to be used in safety, design and analysis decisions. The better the research, the better the “real-world” result – reliable CMFs help transportation practitioners make more informed decisions. This tip sheet provides information to help ensure your CMF is high quality and free of common biases.
