An intersection had 13 crashes last year. The 4 legs of the intersection had 2-way ADT values of 9671, 2893, 9506, and 2611 vehicles last year. Calculate the RMEV for this intersection?

527

Explanation:

Data provided in the question:

Number of crashes per year at the intersection = 13

The 4 legs of the intersection had 2-way ADT values:

9671, 2893, 9506 and 2611 vehicles last year.

Now,

ADT = 9671 + 2893 + 9506 + 2611

= 24,681 vehicles

Rate per Million Entering Vehicles, (RMEV)

= [ (crashes per year) : (Approach ADT per year) ] * 10⁶

or

RMEV = [ (13) : (24,681) ] * 10⁶3

or

RMEV = 526.721 ≈ 527
