THURSDAY, July 28 (HealthDay News) -- Speed cameras installed on
major highways are a cost-effective method of preventing traffic
accidents and motor vehicle deaths, researchers say.
Traffic accidents claim about 1.3 million lives worldwide every
year, according to the study published online in the journal
Researchers did a financial analysis of speed cameras mounted on
major access routes in Barcelona between 2003 and 2005.
They found the expenses associated with the cameras
(installation, operation, ticketing and police time) were easily
outweighed by the costs stemming from traffic accidents that
occurred in Barcelona between 2003 and 2004 (medical treatment,
damages to property and lost productivity).
The researchers also projected that in the first two years of
operation the speed cameras would result in 364 fewer accidents and
507 fewer injuries.
Fewer accidents and injuries, the study concluded, translated to
big cost savings. The researchers calculated the net savings
resulting from the speed cameras totaled $9.8 million over two
"Our results show that the installation of speed cameras on the beltways of Barcelona has net benefits for society even under fairly conservative assumptions," the study authors wrote.
