FIGURE 10. Program Results for Addressing Lane Departure and Speeding-Related Fatalities – Long Description

Figure 10 is a graph displaying annual traffic fatalities. The horizontal axis unit is the year, ranging from 2004 to 2010. The vertical axis unit is the count of traffic fatalities, with an axis range from zero to 600. Three series are present in the graph: Total Fatalities, Lane Departure, and Involving Aggressive or Speeding Driver.

The chart highlights that the HEAT Program was initiated in Spring 2006 with sustained enforcement through July 2007. This is accompanied by a drop from 151 traffic fatalities in 2006 to 115 traffic fatalities in 2007 among the crashes involving an aggressive or speeding driver.

It is noted that in 2009, there was expanded implementation of shoulder rumble strips and rumble stripes. Between 2009 and 2010, traffic fatalities related to lane departure crashes correspondingly decreased from 117 to 103.

In 2009 there was also a renewed intensity in enforcement levels for aggressive driving. Between 2009 and 2010 there was no change in the number of traffic fatalities involving aggressive or speeding drivers, with 86 of such fatalities each year.

Total fatalities demonstrates an overall downward trend, with 567 traffic fatalities in 2004 decreasing to 411 traffic fatalities in 2010.
