I-40 WB near Airport Blvd Fatal Crash rates for intersections are typically reported as the number of crashes per million entering vehicles (MEV) and are commonly calculated with the following equation: 3/8/2016 10:04 PM

1,000,000 x NUMBER OF CRASHES 365 x NUMBER OF YEARS x ENTERING AADT

CRASH RATE =

Table 2-7 shows the crash rates for intersections in Morrisville where AADT data are available. Intersection crash rates are useful in gauging the relative safety of an intersection in comparison to other intersections in the study area. The crash rates are based on 2013 AADTs and 3-year crash data from June 2013 to May 2016. The average crash rate of studied intersections is 0.79 crashes per million entering vehicles. Despite an average entering AADT, the intersection of NC 54 and Morrisville-Carpenter Road has the highest crash rate, due to its higher than average number of crashes.
