Speed & Redlight Cameras

 

I was just wondering, on the 2 camera files, are the coordinates for the speed and redlight cameras locations always given at the center of the intersection even though there is only one camera? I always use the location at where the actual camera road sensor is. This way, the GPS indicates with a dot on which corner of the intersection it's sitting at.

camera pOI location

All of the red light camera POIs I have submitted have been at the center of the intersection. In my area there are no intersections with only one red light camera of the four possible locations. There have been several with two cameras on one street and none on the other street.

The center of the intersection gives the most reliability to insure the POI actually alerts. Changes are always made and a two-camera intersection could become a three or four-camera one.

When we had school-zone speed cameras, all of them were installed in pairs, one for each direction. They were not near each other but at opposite ends of the school zone, which is limited to 440 yards or 402 meters. The POI was placed at the midpoint between the two cameras. Because of the long alert distance inherent in the speed cameras in running POI Loader, there is more than sufficient alert distance.

Globe Turtle does not take the coordinates we submit without confirming them on Google Earth. She can and does modify them based on their policy.

The members who report these camera locations have done the job in a conscientious manner. I have approached many in locations all over the U.S. and the POIs have all been properly located.

New Camera Locations

Most of the intersections here are single camera. I've submitted camera locations before and have always used the road sensor as the location to indicate that corner or lane(s)using Google Earth Pro coordinates. I have noticed that the location was entered in the files as the center of that intersection even though there is only one camera there. I was just wondering why that is. Thanks for the explanation, for future installs it would make sense.

Here we go again

In one form or another this topic keeps rearing its ugly head.
You do know that some Cameras can be turned inside the housing to change where it points to. Also, as your driving do you really want to take your eyes off the road and look at the gps to see where that camera is, not that i think you could see where it is anyways, unless you have intersection views. The idea is not too run the light. Your hinting you want to run a red light, by wanting to know where that Camera is.

All I asked a was simple question for submitting 7 new camera locations. Unbelievable!

The accuracy stated by Garmin is 10 meters (30 feet) so the centre of an intersection would make the most sense.
