In May 2007, Montgomery County, Maryland,
implemented the state's first automated speed enforcement program, with camera
use limited to residential streets with speed limits of 35 mph or less and
school zones. Changes were made to the program over time. In 2009, a state
speed camera law increased the enforcement threshold and restricted school zone
enforcement hours. In 2012, the county began using a corridor approach, in
which cameras were periodically moved along the length of a roadway segment.
Results:
- 59 percent reduction in the likelihood that a vehicle was traveling more than 10 mph above the speed limit at camera sites.
- When interviewed in fall 2014, 95 percent of drivers were aware of the camera program, 62 percent favored it.
- The overall effect of the camera program . . . was a 39 percent reduction in the likelihood that a crash resulted in an incapacitating or fatal injury.
