Just curious about this.... Lets say you have a route you normally go to get to someone's house, includes the freeway. Your Nav guide tells you the way to go, but tells you to get off at a different exit than you normally do. So when you drive the route, and you get off the exit you normally get off at, obviously the route guide adjusts to your change and directs you down this new route, and you arrive at your destination. Now, lets say you drive to this destination a week later. If you punch in the destination, does the Nav system "remember" your last trip at all, and give you a guide that includes exiting the freeway at the exit you usually take, or does it give you the same route as it did before? Just wondering if the nav system has this capability, or if you have to manually go through and adjust each exit/turn until it gets it right.
:lol: :lol: :lol: Good one Tony!!! I've finally got a good name for my NAV voice... "Dora". THANKS! :lol: :lol: :lol:
<div class='quotetop'>QUOTE(unruhly @ Jan 31 2007, 11:40 AM) [snapback]383343[/snapback]</div> If I remember correctly, the Nav system CAN remember a route, because it is possible to "record" a route. When you're not being guided on a specific route, you can hit "record" or "record route" at any time and it will record that route. I've never tried it, but I know that it can be done. Please correct me if I'm wrong, as I do not own a Prius. I DID, however, spend a week driving one around and noticed the "record" option.
yah I konw about that too, but what if you drive to the same destination, but you are starting from a different point? I'm asking, once you get to the freeway and drive the half hour, and get down to exit A vs exit B, when the nav originally told you to take exit B but you always get off at A, would it tell you to now get off at exit A, or will it always tell you exit B no matter how many times you get off at exit A instead?
<div class='quotetop'>QUOTE(ucsbgaucho @ Jan 31 2007, 11:22 AM) [snapback]383414[/snapback]</div> The Navigation system does not have the capacity to "learn" and improve its route based on your driving patterns. That would be nice to have... but I don't think there are any systems that can do that at this time. What you can do with the Prius, is assign presumed speeds to 3 types of roads: Residential, Major Street and Freeway. In the data base the Prius has, it identifies all of its streets into 1 of these 3 categories. When it calculates the fastest routes, it applies these presumed speeds to decide whether to take 1 road versus another. By you changing these presumed speeds, you can shift preference from one type of road to another. I hope this helps - its a pretty powerful tool which can be helpful, if you learn all of its functions.
<div class='quotetop'>QUOTE(John in LB @ Jan 31 2007, 11:47 AM) [snapback]383435[/snapback]</div> Agree. That sure would be nice. A work around I have used is to create a memory point on a particular street near the exit that I usually like to travel. Then you can add that to your route as a destination just before your final destination. The other way is to add a preferred road in a similar manner but selecting that using a map can get tedious.
That's what I figured, that you'd have to edit the route manually, point by point. It's not like I need to know how to get where I'm going, since I've been there many times, but just wondering if the system was a "smart" system. I think that would be a great development in the next generation of nav systems. It can analyze your driving patterns, whether you always avoid a certain stretch of freeway, or you prefer divided roads, or you always go a certain way because of some condition the nav system doesn't know about (construction, etc), and it'll begin to suggest routes based on those preferences.
<div class='quotetop'>QUOTE(ucsbgaucho @ Jan 31 2007, 04:25 PM) [snapback]383571[/snapback]</div> That system already exists.... Its called a SPOUSAL Hyena Intervention Protocol (or s**t). Usually the s**t system sits in the passenger seat or possibly in the back seat. Using mechanical intervention (pressing finger on your arm / shoulder), the s**t system insistently makes you ignore the NAV system and go the "smart" route.... Note: Ignoring the s**t system, will only make your lights blink and ultimately your MPG (Male Pride & Gonads) dwindle.... oops... my wife just read what I wrote... oh s**t.... :angry: <div class='quotetop'>QUOTE(ucsbgaucho @ Jan 31 2007, 04:25 PM) [snapback]383571[/snapback]</div> Seriously, I actually think the next significant advancement will be integration with live traffic information (for a monthly fee of course). With this approach, the routing will truly be optimized... (of course the philosophical question of the day is: What happens when all cars have the same system? Do they all then go the same route - resulting in a jam caused by the NAV systems themselves?... hmmm) <div class='quotetop'>QUOTE(jrfaris @ Jan 31 2007, 01:08 PM) [snapback]383489[/snapback]</div> I thought of another work around that I have never used. In your memorized locations, you are allowed to have up to 10 spots that you want the system to "avoid". What if you made the exit a point which you wish to avoid... Experiment...
I don't believe this is correct. To my knowledge it only uses the speed settings to calculate the time of arrival, but it doesn't use these to calculate the route.
<div class='quotetop'>QUOTE(Sho-Bud @ Feb 1 2007, 04:44 AM) [snapback]383810[/snapback]</div> Absolutely uses them. Quick 1 and Quick 2 are based on time of arrival analysis. They are not based on mileage (which is Shortest route).
<div class='quotetop'>QUOTE(John in LB @ Feb 1 2007, 03:27 AM) [snapback]383786[/snapback]</div> Hehe, I always have thought that too... Even when you're in the checkout line at the supermarket, and someone opens a new register and everyone in front of you rushes over to that new register, suddenly you're next in line. That's the problem with live traffic, is there's always a slight delay in what it's telling you. Just like satellite radio traffic stations, you know they actually only give you a new traffic update every 15-20 minutes, so 3 out of 4 "reports" are just replays. Easy to figure that out when you drive the route that they say an accident is on, and you drive by the spot and there's nothing left.
<div class='quotetop'>QUOTE(John in LB @ Feb 1 2007, 03:27 AM) [snapback]383786[/snapback]</div> This will work, but be advised that if you need to detour (Map View : Detour) the Nav will not detour you through the "avoid" areas. I wish there were a way to say "avoid this place, but it's OK if we need a detour."
<div class='quotetop'>QUOTE(John in LB @ Feb 1 2007, 05:02 AM) [snapback]383811[/snapback]</div> But there is a bug in that. See this Priuschat thread
<div class='quotetop'>QUOTE(aforkosh @ Feb 2 2007, 01:25 PM) [snapback]384646[/snapback]</div> No, there is no bug. I fully agree with the thread you indicated. You may not like the results, or they may not be intuitively correct. However, given all of the computing rules set up, quick 1 and quick 2 attempt to find the least amount of time options. Short is solely based on mileage.
<div class='quotetop'>QUOTE(John in LB @ Feb 1 2007, 03:02 PM) [snapback]383811[/snapback]</div> I have to disagree with you. You are right that Quick 1 and Quick 2 are based on time of arrival analysis, however it does not use the speeds which the user can set, but the speeds which are encoded in the maps. The speeds that the user can set are only used to give the estimated time of arrival, after the route has been calculated. The manual is clear about this, but you can also test is yourself. Have the system calculate any route, remember distance and time of arrival. Delete the route, change the higway speed to 5 miles per hour or so. Calculate the route to the same destination. Yo'll see that the system calculates exactly the same route, same distance. Only the time of arrival has changed (a lot).
<div class='quotetop'>QUOTE(Sho-Bud @ Feb 6 2007, 05:02 AM) [snapback]385974[/snapback]</div> Thanks for pointing that out. I didn't realize that there is more detailed road speed information in the database. That makes sense and explains some of the "bugs" others have reported. So the recommended routes are based on built in road data while the owner's speed settings are used to estimate his ETA.
