Photograph of two cars wrecked in a crash.

speaker notes:

This is an approximately 30 minute presentation on the topic of red-light running (RLR). Topics covered include:


slide 2

Traffic Signals

slide 3

Intersection Fatalities

Pie chart indicates that 65 percent of fatalities occurred at unsignalized intersections, 31 percent occurred at signalized intersections, and 4 percent were unknown.

speaker notes:

Major Points to Make:

Even though signalized intersections make up only 10% of intersections in the U.S., signalized intersections account for nearly a third of the fatalities that occur at intersections.

Intersection Definition

Aerial photograph shows the center part of a 4-way signalized intersection highlighted in red. The red shading also covers the areas on the approaching travel lanes between the edge of the stop bar and the square that is the intersection proper, including those segments of crosswalks that run between the stop bar and the center of the intersection.

Safety Facts About Red-Light Running

Line graph depicts red-light running fatalities from 2000 to 2007. Fatalities are slightly lower in 2007 than they were in 2000.

Safety Facts About Red-Light Running

Line graph depicts the total number of red-light running crashes, number of persons injured, and number of injury crashes for each year from 1997 to 2004. The data trends are roughly parallel as they edge downward over time.

Types of Crashes

Iconic images depicting a right-angle crash, where vehicles approaching the intersection at right angles intersect in a crash; a rear-end crash, where one vehicle cannot stop for the light in time and crashes into the vehicle stopped in front of it; and a left-turn crash, in which an oncoming vehicle is hit by a vehicle attempting to cross its path.

Types of Red-Light Runners

Graphic indicates there are two types of red-light runners: unintentional, which can be mitigated by engineering countermeasures, and intention, which can be mitigated by enforcement countermeasures.
