I'd like to know if it's possible to set-up a speed alert, that will function whenever driving on a specific road, highway or freeway (eg. US101, SR35, Howard Ave, First Street, etc.).
Something like US101@65.csv or First Stret@25.csv., so whenever the GPSr recognizes you're driving on "that" road, the speed alert will function.
Thanks for your time.
Alerts are only done based on specific locations with longitude and latitude identified.
You could set up a bunch of points along a specific road as a POI file and have them alert, though.
Too bad the GPSr itself doesn't have a feature built-in to the software, that would allow the user to "manually" select a non-POI based speed alert.
Are you listening Garmin???
It's called cruise control !!!!! (joke)
Cruise is not practical in city driving...my grandparents' old Buick Electra 225 - 1970s vintage - had a speed alert function, where you could set a target maximum speed, and when you hit that, there would be a loud beep...if car makers could do that then, they certainly could do it now.
As they say down South "I was jus funnin !"
I don't use it in traffic but I do use it as low as 30 mph (in my van) on some of the lower traffic, scenic roads down here where they really bang you for going over 30-35 mph.
BTW - 70 era Buicks are not vintage to us "over 70" folks - they are CLASSICS
Yeah, I use cruise control all the time in the city. There is are many spots where it is soooooooo easy to speed. There is one stretch of road that is 45, can you can get up to 60 easy. So I set my cruise control to 53.
I wish that the GPSr would tell you the speed of the road based on the type of road, although it wouldn't be perfect, it would be a start.
This device may achieve your purpose, but I am not sure.
That's a little over the top for me.
MrKenFL actually got it right, when he suggested I use cruise control.
OTOH (on the other hand) it would great if that feature was incorporated into the Garmin software.
Oh well, I can always dream...
I am not sure, but I don't think that navalert can give the PSL of a particular road. Could be wrong though.
tailspin, I imagine that that function would be much more complicated to implement than it may seem at first.
why? All interstates are 65 (some higher). All neighborhoods are 35 or 25, depending where. I don't see why it would be so hard. Of course, it wouldn't be perfect. But the DOT usually assigns a speed limit by the type (and where) the road is.
Well, let's see ... to start with, there are probably millions (several millions?) of miles of roadways in the US alone for which this would have to be programmed. Every single segment of every single street would likely have to be programmed individually.
As far as we know, the current map database does not include that actual speed limit of roads in the data, so all of this information would have to be collected and then maintained. A huge undertaking.
Localities set the speed limit on most surface roads. What happens when they change it (which they do sometimes randomly for political reasons)?
The speed limit changes on many roads in many places, so all of the change points (in both directions) would need to be known, cataloged and programmed.
All interstates are certainly not 65mph. Around me they vary from 55 to 60. Isn't part of I-95 around the north part of Richmond 50mph? It used to be anyway. What about ramps?
Some residential streets are 15 mph.
I'm not trying to argue. I'm just pointing out some of the things that come to mind. Think about how much people complain now that the ROADS are not in the database. Imagine the outcry if (when) the speed limit data wasn't updated.
I am not aruging either, and I didnt take your valid points as arugement, but rather conversation.
However, they could assign speed limits to the type of road (which they already have in the maps). It wouldn't be perfect, but at least it would give you a sense of what the speed is...of course, dummies would rely on that and get speeding tickets...lol
...of course, dummies would rely on that and get speeding tickets...lol
And if it wasn't 100 percent accurate, people would be in here screaming about it.
Ok Ok, I give in, it isn't a good idea without a lot of time, effort, and money involved. LOL.
My c530 is incredibly accurate in calculating my estimated time of arrival. How does it do that if it does not kow the speed limits of the roads on the selected route? Last year on a trip from Wisconsin to Tennessee, the c530 estimated time of arrival was within 3 minutes of its first prediction when I left home. I found that to be amazing.
There is a formula they use - that involves the kind of roads you're on and their speed limits, and an overall average speed for the whole route - and predicts a time - it will adjust that time as you drive, based on your driving habits - like going faster than the average it expects will shave off a few minutes here & there as you travel...or add time when you stop, or get stuck in slower than expected traffic.
What I'm suggesting is a simple "user set" alarm, activated by the GPSr and independent of any map, road, street or highway. When the "satellite" detects your "vehicle" traveling above a user preset speed, no matter what road you're traveling, an alarm or reminder would sound.
I hope this makes sense...
Your assumption is correct.
Road speed is already in the map data. Otherwise, your ETA can not be calculated. Some GPSr manufactures chose to display them, while Garmin decided otherwise.
Now newer maps also contain historical speed data for major roads. So, if you're traveling below that speed. It will know there is a traffic congestion and reroute you.
Yeah, we sorta got off subject there for a bit. I would take either.
Actually, my Audi A6 (2003) has a speed alert setting through the onboard computer. You can set a maximum speed and the computer will get mad at you when you go over that speed by blasting an annoying beep. The first time I used it, I couldn't figure out how to turn it off and I had the max speed set for 35mph but got on an interstate going 65 and had the damn thing screaming in my ear until I could pull off, get out the manual and shut the alarm off.
Needless to say, I haven't used it since!!!
Well, obviously that would be a bit more simple to implement. I was just commenting on your original question having to do with being on a specific road and having it programmed with the speed.
a '72 Electra, and that was a nice feature for night driving. Turn the dash lights out and the buzz would alert you when the set speed was obtained. BTW, you could be a shade-tree mechanic on those cars then too.
The answer is yes! This exists out there already. This exact topic was brought up not too long ago. Here's what I wrote:
It can be done using a PocketPC. I've tried a free program that works very well and has many features, called GPSAuto by Roman Nepsinsky. You can define separate, custom visual and sound alerts for up to 8 speeds, day and night colors, metric and imperial units, tracks trip and total distances, etc.
Other than that, TomTom's safety features offer something similar. They include blocking most buttons when in motion (forcing you to pull over to take care of more distracting stuff) and hiding the map display above a certain speed (you still hear the voice alerts), to prevent you from taking your eyes off the road. Both features can be enable or disabled by the user.
TripMaster for TomToms does it
I know this does not help you, but if any TomTom owners are out there they may be interested in it.
One my wife's car, if you go past 65, it starts to shake, so I guess I have the same thing as the audi...lol.
Hey, whatever works from getting a ticket. I sounds like you should get that car in for service on the front end before it starts to "rattle and roll". Did I really say that? LOL.
Heck, it is 11 years old. We are going to get a new one soon (hopefully, we are trying to get a house too).
