The Des Moines Police Department says automated traffic cameras are helping reduce collisions on metro roads.
Cameras were put in place in June 2011 at five intersections and eastbound I-235 to address red light violations and speeding.
The intersection that’s seen the biggest reduction in collisions is MLK and School Street. In 2009, there were 16 wrecks reported and in 2010, there were 22.
In 2011, that went down to 10, and then last year, when cameras were operating for an entire year, there were only five.
The other four intersections with red-light cameras saw between three and five wrecks in 2012.
