"Any highlighting of the speed camera was purely coincidental," a spokeswoman said.

All the sites that received new cameras were identified as having a high crash risk based on analysis from independent traffic experts on fatal and injury crashes.
At the time of their introduction Inspector Peter McKennie, the operations manager of road policing, denied that speed cameras were used to collect revenue, pointing to the fact that money from camera infringements goes to the Crown's consolidated fund, not to police.
International research showed speed cameras encouraged drivers to slow down and reduced speeds helped reduced injuries and fatalities on roads, he said.
"Road crashes have devastating impacts on families and communities," McKennie said.
"We're only interested in the impact the cameras have on encouraging people to slow down to safe and appropriate speeds, so they get to their destination safely."
McKennie said the expansion programme would be backed by other measures, including a highly visible police presence on high risk routes.
