U-Turn Amusement.....

[f4phantomii]

I wish I could post some screenshots. This is so comical it just has me in tears.

I won't be able to take my normal route home this evening due to Superfund Site cleanup in the "Colonial" section of town. It is slated to last through this summer.

Unfortunately, when you live on an island, there aren't many alternative routes to take. Only one road on/off.

A co-worker and I have agreed to try different routes and time them to see which is going to work out better for the long term. I realized that was a perfect test of the Que's "Trip" statistics.

I went to plan the route and save it (the first time I've done so), but I absolutely cannot get the Que to stop making u-turns. I keep adding Vias in a vain effort to basically force the route. I'm up to 5 u-turns, despite the fact that I have instructed the Que to avoid them.

In fact, in addition to the u-turns, it has me going in a complete circle in two the square-a-bouts (we Americans are too silly to use the European round-a-bout)!

And two of the u-turns are on the same street! It actually wants me to go partially down a street, make a u-turn, route completely around the area and turn back onto the original street going the wrong way to pick up the via. It does this even when the two vias are only 100 feet apart! I can't believe it sends me on a 1.5 mile work-a-around to reach two vias that are only 100 feet apart on the same street!

Oh well....guess I'll just drive it and save it as a route when I get home.....and wait for Release 3.

(...still shaking head in disbelief....),

Why that old SAAB Viggen?? At least the Gripen can make U-turns

[apersson850]

I seem to recall when Gripen (Griffin) made U-turns when it better had not...

[mcvpjd3]

Are you sure this is routing for a car and not pedestrain?

[dhamments]

Have you tried setting preferences to avoid u-turns?

[f4phantomii]

Let's see....



Yes, I have "Avoid U-turns" set in the preferences.
No, I don't have it set in pedestrian mode, it is set for vehicles.
Okay, okay....if everyone is such a fan of the Gripen, then I how is this signature?

f4phantomii,

You might try playing with Routing Prefs like "avoid highways", although you may never get off the island.;) I have noticed that in the areas where I drive, if fastest route is selected, the Que seems to be drawn to main arteries like a magnet, even though you may know of short cuts. I like to often take back roads the iQue would normally not select in routing. The avoid highway setting often gets the iQue to route me exactly the way I want to go, off the beaten track. However, this setting WILL use highways when there may be no other option, such as your one way out/in. It is possible that some mapping data is incorrect regarding some of your roads, particularly if a route calculation wants you to drive the wrong way on a one-way street, etc. If that is the case, Release 3 isn't going to fix your problem, either.

I use trip to gather statistics regarding where I have driven. I do not set a route. I just reset all values and drive. Perhaps this will work for you as you try various routes you devise.

[f4phantomii]

To be clear, the iQue didn't want me to drive down a one-way street, just the opposite direction from my intended destination.

Since I couldn't do a screen shot, I've included a crude marked-up map here just to show the routing the iQue wanted me to take.

This was at the point I just gave up. I didn't need the route to do get the trip statistics, just wanted to play with my iQue. It did occur to me that turning off some of the other "Avoid" settings might do the trick, but I didn't try them.

I figured if I defined enough vias, I could force the route...guess I wasn't as smart as the iQue on that one. It followed my instructions to the letter and in order. I'm curious to see if the improvements in Release 3 make any difference.

Hopefully the map will give everyone as much of a chuckle as I got from it.

Isn't modern technology wonderful? I am doing the same thing, playing every chance I get. My wife still remarks when I take it with me to go to the milk store a mile away (of course I don't always take the most direct route). Just love tech, and have for the 37 years I've been in the business.

Guess the IQUE is determined to help you it's way, not the way you want (grin).

Be carefull when you add via's. It will want to take you through the exact spot, so if you tap on a street you want it to take you to, make sure you tap on the side of the street that you want to go down, if you select the other side it will get you to that side of the street before it continues on.

This is very true and annoying. You can of course always delete that via when you're in the area and continue on your way.

I have seen exactly the same problem as the aircraft show on his map image. I couldn't understand why it just refused to route the shortest way, straight ahead, but took a detour around the block. No matter what kind of vias or routing selections I did, did it pass a certain point. It was like the road was blocked.

Guess what. It was blocked. When I zoomed in enough, I could see that two segments of the road weren't connected on the map. They were so close, that at an ordinary zoom level, I didn't notice.

If you have European maps (CS 5 or CS 6, doesn't matter), use Mapsource and take a look at N56º 55.631 E014º 03.042.

Zoom in as much as possible and look at the intersection. On the map, the roads don't connect, but in the reality, they do.
The iQue would never route across this intersection, or course.

Then take a look at N56º 54.853 E013º 58.842. That crossing looks fine, right? But in Metroguide 4, it's the same thing as with the one above. I reported the error to NavTech, and in Metroguide 5, as well as in CS 5 and CS 6, it's correct.

Now the problem referred to above is perhaps not visible to the naked eye. The roads may very well connect on the map, but perhaps some routing attribute says that you can't pass a certain point.

I don't know, this is just a suggestion.

Hee hee. Reminds me of the time my iQue wanted me to do donuts in the midde of one of the busiest intersections in Dallas (Addison). "Make a U-turn, then make a U-turn," it told me. I suspect it was probably more a map data problem than the iQue software. Still that would have been a fun one to explain to the officer. :)

f4phantomii,

I just noticed your rma counter in your signature:) Appropriate.

Betty is really an emotional woman who pretends she is scientific and mechanical. She's nostalgic for the cruise around Main Street waiting to be picked up. Every once in a while she looses it and give a wild screech and may get sick to need the attention of a Garmin doctor.

This past weekend had betty take me skiing 3 hours away. The route took me to west point. i asked the guard with the ak47 about a road betty wants me to take. he said the road is shut down during bad weather. :) :eek: Just a little fun with our betty!
