Do Traffic Calming Measures Work?

"Cities are also installing textured crosswalks, traffic circles, and sidewalk "bulb-outs" that remove the shoulder and extend walkways up to the road. Speed humps and tables, however, are the most common devices used, according to a study by the Institute of Transportation Engineers.Such measures have been a fixture on many European roads since the late 1960s, according to the ITE. In the US, though, such devices didn't catch on beyond such cities as Berkeley, Calif., and Eugene, Ore."
