A local agency expects a 14% reduction in right-angle crashes with a CMF of 0.86. If the AADT on the major street is 10,000 and on the minor street is 8,000, what improvement can they expect?

A local agency expects a 14% reduction in right-angle crashes with a CMF of 0.86. If the AADT on the major street is 10,000 and on the minor street is 8,000, what improvement can they expect?

• A. A 10% reduction in right-angle crashes
• B. A 14% reduction in right-angle crashes
• C. A 20% reduction in right-angle crashes
• D. A 25% increase in right-angle crashes

Answer: (B)

To determine the expected improvement in right-angle crashes using the given data, start by understanding the context of the crash modification factor (CMF). A CMF of 0.86 indicates that with the implemented safety measures or changes, the expected right-angle crashes will be reduced to 86% of their current level. The local agency anticipates a 14% reduction in right-angle crashes in relation to the current rate. This means that they expect 14% fewer right-angle crashes to occur once safety improvements are made. Using the CMF concept, they have effectively assessed that the expected outcome aligns with their forecasts, showing that they understand the relationship between the current data and their safety strategies. With an average annual daily traffic (AADT) of 10,000 on the major street and 8,000 on the minor street, this suggests a significant frequency of traffic interactions at the intersection where right-angle crashes might occur. The expected 14% reduction is directly linked to their analysis of current crash rates and anticipated improvements. In this context, the choice indicating a 14% reduction directly reflects the agency's forecast and understanding of the effects of the CMF on crash rates, supporting their projected safety improvements as a practical and measured estimate based on historical
