Speed cameras

Baltimore Sun staff writers Scott Calvert and Luke Broadwater spent more than six months investigating the proliferation of speed cameras in the region. They obtained detailed citation data from Baltimore City, Baltimore County and the State Highway Administration, which oversees the state's highway work zones. 

The public records requests yielded data on more than 2 million government-issued citations, including the date, location, tag number and recorded speed for each. The Sun could then, for example, track trends at certain locations and document multiple ticket recipients.

As of mid-October 2012, the city -- with the largest traffic camera system in North America --  has issued 1,552,967 automated speed citations.
