Red Light Camera POI

I had noticed this routing behavior as well and thought it was a problem with the particular POI I was approaching though I eventually figured out what was going on. If you are driving "free" without any route, the alerts will go off if you are heading towards an RLC. If you are following a route and you are approaching an RLC, but your route does not intersect the RLC, then it will not go off.

This is at least what I am seeing on my 765T at an RLC in New Hyde Park, NY. The intersection has a channelized right turn which bypasses the intersection and the RLC. My 765T routes me on that channel and the alert does not go off because I never actually intersect that RLC. When I drive back, the alert does go off because I have to drive through the intersection and make a left turn.

My understanding is that when not navigating a route, you will get the alert if the point is on the street you are driving on. When navigating a route you will get the alert if the point is on your route.

This is pretty much accurate for my 255WT too.

That is the way it already works!

The intersection is not at a right angle. It has an oblique angle. You make a right turn by going on a short ramp that bypasses the main intersection where the POI is located. Even though the POI was moved closer to the ramp, Aardvark still doesn't get an alert because his active route goes through the ramp rather than the main intersection. This is a one-in-a-million problem.

My 1490 and 265 alert on the set distance from the intersection no matter which way I am traveling. They even alert on parallel streets if they are within the set distance. This is on a route or not.

Same here, except i will get a large white screen telling me the address if i'm not on a specific route otherwise it just alerts me and gives me a small something or another on the screen which i can't read.

Should the speed and red light camera POIs be loaded at the same time? If so, why?

At the same time? They are two different files and notify you at different distances. You can set your own distance if you wish, like i do. I personally use 100 meters for the RLC's, and 400 meters for the speed cams. So that's about, 3 feet to a meter, you can do the conversion. But you don't have to load them both if you don't want to. Hope that answers your question

The speed and red light camera files operate independently. One, or the other, or both can be loaded at the same time.

They don't have to be loaded at this same time. But if you are loading them with POI Loader new data is overriding old one. So if you will load RLC file and then speed file you will lose RLC data. That's why it is better to load everything together. I'm not sure how it works with newest POI Loader, but older versions works this way.

Practically best way to load POI's is to make folder (for example named POI_files) and then inside it make folders with appropriate POI data (for example folder speed_camera, and place data with speed cameras in it. same with any other POI data). This way you will have order in files and will be able to load them all without loosing any data.

I get alerts on my 885t regardless of wether I'm traveling a "Route" or not. And I get the alerts even when I get kinda close to the instersection and am not on a road that will pass thru that particular intersection. It's a simple proximty alert.

Same here, I get the warning irrespective of whether or not I'm travelling on a route.

I have a new 1490T. The red light alerts come on whether I am on a set route or just driving with the 1490 on. I manually set the alert with POI Loader to come on in 800 feet of the camera intersection which is just about right for a red light warning. You should get the audible alert and also see the icon on the screen at the intersection. If you stop at that light, when I start up and go through it, the audible alert comes on again which is just fine.

Robert, that is what I do except that I set the distance at 600 feet because most locations in my area have a speed limit lower than 55 mph. Glad to hear it's working well for you.

My streetpilot 7200 has the red light camera poi, and in menu and audio (or alerts?) there is a way to enable/disable audio and visual alerts for custom poi's.

When it's on - and as I'm driving around, it will tell me I'm approaching a red light camera - which TO ME, got annoying after a couple of weeks... especially since I pass several on my daily route..... I actually turned that option OFF... so now I don't hear the message constantly.

That is why I set the alert distance at 600 feet using POI Loader in manual. At this short distance, I get one audio alert. An alert distance of 1320 feet produces four audio alerts.

Either way, if you stop-and-go, there is an additional audio alert.

dobs108

What are the standard set points of audio alerts? If 600 ft is 1, what are the next few?

Using POI Loader in manual, the alert distance can be set to any value. The first alert happens at that distance. I don't know whether the alerts after the first one happen at specific distances or if they are based on time inside the alert distance.

This comment is very interesting. I agree that stop and go creates additional alerts. I am not sure whether or not I have to have come to a complete stop or whether it is just being below a certain speed.

However, I do have the default 1/4 mile (1320 feet)alert set and I get only 1 alert tone on my 765T.

Wonder what the difference is?

I don't know what the difference is, but it may be my nuvi 760 vs. your 765. They are different units with different firmware.

In every case when I load RLC POIs at 1320 feet, either in manual or express mode, there are four audio alerts before reaching any RLC POI, when driving at a normal speed of 30 to 40 mph. When I shorten the alert distance fewer alerts sound.

It may be a setting on whether alerts repeat or not.

I get alerts for red light and speed cameras when just driving with no route set and also when on a route.

an alert is an alert regardless of whether you are just looking at the map screen or are navigating a route.

That should be the way it works, you shouldn't need to be on a calculated route to get an alert - I know my 760 alerts me regardless.

I have the alert set for 500 feet. Normally I only get one alert approaching an intersection, but if the light goes red and I have to stop, I'll get another alert just before I enter the intersection. I've always assumed it had something to do with the time interval as well as the distance.

And when I'm on the Long Island Expressway, and there is an RLC at an intersection on the service road, I'll sometimes get alerts as well. It really confuses passengers, wondering why there is an RLC on the expressway.

Traveling I-95 through the center of Providence, there's one section near exit 22 (leading to Hartford, CT) where there are four red light cameras on the roads that go over the highway at that point, two on the left and two on the right. My RLC distance is set at 528 feet (.1mi/.16km). All four go off at once, leading to a cacophany of noise as I get Star Trek's red alert siren echoed.

Even going over highways that runs near a redlight camera sets off the alerts in my 360
