Answer:
527
Step-by-step 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
