"The biggest thing we love ... is we place those (cameras) by collision statistics," said Sgt. Joerg Gottschling of the Calgary Police Service traffic section. "If we do a new site, if we are going to install a new camera, the next site is always selected by the next highest crash site.

"Our intersection locations are all determined where we are trying to eliminate collisions."

Gottschling said they've had up to a 50 per cent reduction in collisions in some areas where those cameras are stationed.

With Google Maps, he noted, all drivers approaching the fixed camera intersection get the warning.

"That camera is only facing one way," said Gottschling. "Let's say it's only facing northbound, but you can approach southbound or eastbound ... you are still going to get Google telling you caution.

"So you're going to go slowly and cautiously through there which, lo and behold, is actually what we want."
