The Truth About Speed Cameras: They Don’t Work
 
<b>NMA Article: The Truth About Speed Cameras: They Don’t Work</b><br/><br/><p><img class="alignnone size-full wp-image-526" style="margin-bottom: 8px;" title="photo-enforcement-zone" src="http://www.motorists.org/blog/wp-content/uploads/2009/08/photo-enforcement-zone1.jpg" alt="photo-enforcement-zone" width="525" height="200" /><br />
Anyone who believes that speed cameras have a large impact on the speed of the vehicles on a freeway should check out <a href="http://radartest.com/article.asp?articleid=100619">this study published last month</a>.</p>
<p>In order to evaluate how effective speed cameras are at reducing driver speeds, Craig Peterson of RadarTest.com conducted an experiment using the speed cameras in Arizona.</p>
<p>Here’s an excerpt from his findings (emphasis added):</p>
<blockquote><p><em>Over a period of weeks this spring I conducted traffic surveys near speed vans and fixed cameras in several locations around the metropolitan Phoenix area. I did the same in Mesa, Glendale, Prescott Valley and Star Valley, Arizona. </em></p>
<p><em>To create before/after speeds, I first measured speeds one half mile before the camera, then at the same distance after the camera. If the speed camera tub-thumpers are right, the </em><em>after speeds should be noticeably slower.</em></p>
<p><em>I conducted the surveys using accepted Institute of Transportation Engineers (ITE) methodologies [...] I sampled cars equally from each travel lane and to make the statistics even more unimpeachable, I recorded the speeds of at least 200 vehicles at each location, twice the number dictated by ITE guidelines. [...]</em></p>
<p><em>Interestingly, the numbers from every site were nearly identical. </em></p>
<p><em><span id="more-514"></span>In [the] composite chart of representative results [included below] from four of the freeway locations, it can be seen that far from slowing traffic, the cameras had no effect on freeway speeds. </em></p>
<p><em>In fact, at some locations average speeds were </em><em>higher after the cameras. Okay, the small increases are statistically insignificant. </em></p>
<p><em><strong>But the numbers are clear: speed cameras do not decrease highway speeds.</strong> </em></p>
<p><em>Aside from a brief dab at the brakes by a few drivers in reaction to fixed speed cameras—frequently resulting in screeching tires from cars behind—most seemed oblivious to them. Hardly any slowed in reaction to the speed vans.</em></p></blockquote>

<p>As Mr. Peterson points out at the end of the article, if speed cameras have no impact on driver speed, then what are they good for?</p>

<p>Oh, right.</p>
