How Speed POI Works

 

Regarding the speed camera POI, I was wondering how it works. Forgive me if this topic has already been covered, but I do have a few questions.

When loading the Speed Camera POI using POI Loader, it asks for a trigger speed above which the POI's will be announced. I usually set mine at 25 so that I get notifications of all cameras if I'm going over 25 mph. What that does is make it so that when I get a warning, it also displays 25mph. The speed camera POI has the speed limit listed in it. I was told that thid speed should be displayed at the individual locaiton of each POI, effectively showing the speed (65, 55, or whatever) at each location coded in the file. Is this information correct? If it is supposed to work like this, then what is the correct method for using POI Loader so that my default trigger speed is not shown on-screen during the alert?

Thanks,
Bill

I think

If you look at the speed file from this site, you will see how it is done.

My understanding is that the poi loader will automatically take the mph in the 3rd column and use it as the speed. I have not tested it as we do not have any here in ks, and I have not made any of my own.

When in manual mode you get the choice between proximity or speed alert. Choose speed and don't put any value in. Then it gets the value from the third column.

For csv POIs, in order for the speed alert to work with the speed entered in the Name (3rd) column, it has to contain an @

Example: Longitude,Latitude,Name@30,Comment

When the alerts are set this way, there is no overriding. Manual mode or number in the file name does nothing for that particular alert. POI Loader's Help section has a lot of good info on this.

variable speed camera!?

There's a fixed camera on Watkins Mill Rd, Montgomery Vilalge, MD which is on a school zone.

There's a 35mph sign posted right before the camera, and also a post with the blinking yellow lights when it's school time with a posted sign of 25mph.

Has anyone seen this before? Is the camera setup smart enough to change speed limits during the day, and between a school and non-school day?

I Think So

I believe these cameras can self-calibrate tied to a timer function.

We also have school zones

A small suburban community I must go thru every day has a general speed limit of 35 MPH but a school speed of 25 MPH during certain hours from one end of town to the other. The hours are posted on a small sign about 5" x 7" on the speed sign. How strangers are supposed to read it is a mystery to me, but it must bring in money to the town. They have a sign that blinks during the 25 MPH hours but is easy to miss. The other thing is you can go thru the town most any time and not see anybody walking because most of the kids are bused. I doubt you could write a POI for that unless you just set the speed for an all the time limit of 25MPH.

Another place in the main town has a much smaller area around a high school that does the same thing. They have had students killed there however and have a high population of kids on the road. They have significant signals for the time of the lower speed This seems to be a life saving limit as opposed to the first situation.

There are no cameras however.
