The SHSP table below illustrates the overlapping causes of crashes and the need for a multi-discipline approach that involves engineering, education, enforcement and emergency response.
The chart plots all the Emphasis Areas in the Strategic Highway Safety Plan. Areas of yellow, orange and red show a stronger relationship between the crash types.
Example: In the top, left-hand corner, you will see that between 2006 and 2010, Ohio had 2,197 Roadway Departure fatalities where a driver left the road and hit an object, such as a tree or utility pole. As you move across the top row to the right, you will conclude that many of the roadway departure fatalities also involved excessive speed, alcohol and unbelted drivers and passengers. This information demonstrates the need to pool our resources across safety disciplines.
