I HEARD A disturbing statistic a while back that I can’t seem to get out of my mind. Information Display Company had loaned some radar speed signs to Feet First, a great organization all about getting kids (and their parents) to walk rather than drive to and from school. One of Feet First’s directors told me that half of school children hit by cars in school zones are actually hit by parents of students at the same school. I would think that of all the drivers on the road during school hours, these drivers would be most cognoscente of the potential hazards and therefore the most cautious. Apparently not.

Then I came across a new report just put out by Safe Kids USA that might explain this phenomenon. The report, entitled Distracted Drivers In School Zones: A National Report, highlights some statistics regarding driving behavior – particularly in school zones. What they found was that school zone drivers are often distracted and distractions have a real impact on safe driving. Consider some of these statistics highlighted in the report:

• It takes about .25 seconds for an average driver to identify a road hazard (such as a child running out into the street)
• It takes another .25 seconds for the brain to process the situation
• And another .25 seconds for the driver to determine his/her course of action

As the report lays out, if the driver is traveling 30 mph in a school zone, his car will go 33 feet before he even reacts to the hazard.  THEN…

The car will travel another 33 feet by the time the driver applies the brakes…

and another 38 feet before the car actually stops.

Total braking distance from the moment the child is spotted till the car stops…104 feet.

That is IF the road is dry and IF visibility is clear and IF the driver is totally attentive.

On the other hand, if he or she is distracted  – say, by a cell phone call, or a GPS device, or a talk show host, or grooming, or kids in the back seat, or…Well, let’s just say, stopping distance can be greatly larger.

The Harvard Center of Risk Analysis estimates that, in 2003, cell phone use by drivers was a factor in 636,000 crashes involving 12,000 major injuries and 2,600 deaths. Now, add to this other distractions like eating or reaching for that CD cover under the seat.

One more quick bit of information. In 1999, the U.S. Department of Transportation issued a report that highlighted the impact that the speed of a car has on the severity of injuries once an accident does occur. According to the report, only 5 percent of pedestrians would die if hit by a car traveling 20 mph or less. This fatality rate jumps 8X – to 40 percent – when the car is traveling just 10 mph faster, and 80 percent when traveling 40 mph.

So if there was a way to slow drivers just a bit – say from 30 to 20 mph – while driving through a school zone AND a way to draw driver attention from distractions back to their own driving speed, we can make a real impact on the number of accidents and the severity of injuries that occur in school zones.

And that, in a nutshell, is the reason why studies show radar speed signs to be so effective at increasing pedestrian safety in school zones. Long after speed limit signs and school zone posting have become all but invisible to passing drivers, radar speed signs continue to grab driver attention and refocus attention away from distractions and back on their own driving speed.

I really like Feet First’s idea of getting our children back in the habit of walking and riding their bikes to school. I like it even better when I know we are doing all we can to increase pedestrian safety around school zones. The evidence clearly points us in the required direction – eliminating driver distractions and reducing speeds.
