Hello,

Does anyone have the exact GPS coordinates for the six speed enforcement cameras on the Loop 101 freeway in the Scottsdale, Arizona area? I just drove by all of the cameras and marked them with my 10 year old Garmin device. Unfortunately, traffic was too heavy for me to stop at each location and get an accurrate reading. I did my best to mark the locations as I drove by.

Now that I have exported the data into various map programs, I see that these coordinates are off by 100 feet and have manually adjusted them according to the landmarks that I remember. It would be nice to compare with someone else's data.

Hello,

I finally got around to replacing my old Garmin GPS device and have made another run up/down the Loop 101 Freeway (in Scottsdale, Arizona). Here are more exact coordinates for each of the automated speed enforcement locations, taken within three feet of the first camera of each set:

>> Inaccurate data. Removed. See next post where this data has been corrected. <<

Note, a GPS device should handle these coordinates very accurately. However, I found varying degrees of minor inaccuracies with the travel map programs that I tried (WinDoze and Mac). Google Earth was the most inaccurate by about 90 feet. Regardless, it still gives you a good idea of where these cameras are located.

Knowledge is power and driving should never be mindless.

Hello,

It looks as though there were some inaccuacies in my previous data. While the POI's were in the ballpark, they just weren't good enough to make a home run past the ol' traffic camera with. I have since loaded up my car with more microchips than NASA and made another run up/down the Loop 101 Freeway. Here are the updated coordinates:

-111.890753, 33.581397, "Loop 101- Northbound 1"
-111.891327, 33.597205, "Loop 101- Northbound 2"
-111.906522, 33.654515, "Loop 101- Northbound 3"
-111.92386, 33.657683, "Loop 101- Southbound 1"
-111.89132, 33.62039, "Loop 101- Southbound 2"
-111.891263, 33.581858, "Loop 101- Southbound 3"

What device are you guys using to store your POI's? Does your device alert you of an upcoming location or do you have to be looking at the display?

tbone,

I personally use a Garmin GVN52. It is connected to the screen of my factory navigation system via a video switcher from AVElectronics, Inc. The database that I use is from GPS POI US, LLC and seems to be the most comprehensive source for stationary automated red light and speed enforcement locations in the USA. Here are the links for you to read up on everything yourself:

http://www.gps-poi-us.com/index.html

I am still tweaking a few details on this setup and have had some problems with the advanced notice of the POI's that I have loaded. This Garmin unit really just lets you know when you are in the vicinity of a POI, without regard for direction of travel or speed. But, it does merge a great navigation system with the ability to input your own POI's and gives a visual reference on whatever size screen you use it with. It also incorporates XM Radio's Instant Traffic and Weather service, almost a necessity for my commuting.

Now, I have been recently testing the premier device from NavAlert, Inc. and I am extremely impressed. It is a GPS based device specifically designed for the warning of such camera locations and has a host of features that are seamless to drive with. The best thing about this product is that it can be easily updated with the latest software adjustments and POI's from any PC with an Internet connection (no Mac support at this time). I have also done some POI accuracy work for the developer and he is very proactive in keeping this database up to date with camera location, camera view direction, speed zone, and other details. Here is the link for NavAlert:

At last count, there were just shy of 3000 stationary automated red light and speed enforcement locations in the USA. I have considered a radar detector as mandatory driving equipment for years. Since I live in the Phoenix, Arizona area and the place that has the highest concentration of such cameras in the USA (as well as the first such cameras on a multi-lane freeway), it looks as though a GPS based device will also become mandatory.
