Studies were conducted at two sits on rural roads with similar characteristics. The first site was 7.5 miles in length with an Annual Average Daily Traffic (AADT) of 7,400. Over the year-long study period, 42 crashes occurred on this portion of roadway, 5 of them resulting in fatalities. The second site was a 14-mile section with an AADT of 4,700. There were 67 crashes in this section with 5 fatalities. Determine the appropriate crash rates for both locations, and discuss the implications.
