Appendix 9: Crash Rate Comparison Crash rates are typically reported as the number of crashes 100 million vehicle miles traveled. Tables A 25 and A-26 calculate the 2008 crash rates for Branch Avenue and Naylor Road, respectively. This study used year 2008 because it was the most recent year where both crash and annual average daily traffic (AADT) data were available for comparison. Branch Avenue’s total crash rate per 100 million vehicle miles traveled (VMT) is more than two times Naylor Road’s rate.
