Rather than looking year-by-year, here is a graph of the complete 3 1/2 years, showing that 2015 has barely nudged off the moving average of 17.1 incidents per month (The lowest moving average, 14.7, occurred in August, 2013):

The downward trend of 2015 seems to occur in the first half of every year.

- Which intersections have accidents during peak commuter times?
- Are there intersections that are dangerous for under 25-year-olds on weekends?
- Do lighting conditions make a difference?
- How about the pattern of paint?
Intersections are complex, and the problem will persist until the complexities are accounted for. Arithmetic just isn”t enough.
