There is a Quality Rating of 0-5 stars for the reliability of the data. ODOT standard is to use only those factors with a 3-star rating or greater.
You can screen results for the star rating only if you use the Advanced Search discussed below. If there are no 3+ star rated listings, run your search again with progressively lower ratings. Often a lower rating reflects lack of depth in the research rather than poor quality control. Keep your work used to determine the crash modification factor(s) to support your choices if needed.
