Answer:
Step-by-step explanation:
To calculate the crash rate on the road last year, we need to first determine the total vehicle miles traveled (VMT) on the road segment for the year. We can do this by multiplying the length of the road segment (6.1 miles) by the number of days in a year (365) and the two-way average daily traffic (AADT) of 755 vehicles per day:
VMT = 6.1 miles x 365 days x 755 vehicles per day x 2 (two-way traffic) = 5,299,435 vehicle miles traveled
Next, we can calculate the crash rate by dividing the number of crashes (6) by the VMT:
Crash rate = 6 crashes / 5,299,435 vehicle miles traveled = 0.00000113 crashes per vehicle mile traveled
Therefore, the crash rate on the road segment last year was 0.00000113 crashes per vehicle mile traveled.
