Intent: Find the intersection in Oregon with the highest crash rate

2. Introduction Driving can be risky. Things that can go wrong:
Get distracted
Mechanical failures
Other drivers
Crashes can occur anywhere
Goal was to find the intersections with the most accidents

3. Background In 2013 Nationally:
There were 32,719 fatalities due to traffic crashes
There were 2,313,000 injuries due to traffic crashes
The fatality rate was 1.10 per 100 million vehicle miles traveled (VMT)
The injury rate was 78 per 100 million (VMT)
Both were a decrease from that of 2012

4. Background
Oregon in 2013:
There 2466 crashes involving alcohol and 530 involving other drugs

6. Results
The two intersections with the most crashes for 2013 were SE 122nd Ave. and SE Division St., and SE 82nd Ave. and SE Powell Blvd.
