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:

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

2016

CRASH RATE =

Table 2-6 shows the crash rates for intersections in Morrisville where AADT data is available.

MARCH 8 10:04 PM

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

MAY 2016

54 and Morrisville-Carpenter Road has the highest crash rate, due to its higher than average

number of crashes.
