Crash Rate for Intersections exercise
Overview
An example of how to calculate the crash rate for an intersection
Calculate the crash rate for the intersection
In this assignment you will practice how to calculate the crash rate of a given intersection. Analyzing the crash rate provides traffic engineers the necessary information needed in order to address the risks of the intersection. Please solve the following problem:
The number of crashes reported for the following intersection in 3 years is 12. Compute the crash rate.
Solution
For Intersections
Where,
R = crash rate (crashes/million entering vehicles)
C = number of crashes
AADT = average annual daily traffic volume (vpd = vehicles per day)
ny = number of years during which the crashes occured (years)
TEV = total number of vehicles entering the intersection (vpd = vehicles per day)
