| gpspassion: The ETAs with IQRoutes I asked for seem very good, much more like the values expected from real life driving. Thank you very much! |

Well that's good news and shows that IQR works in Europe too, in France I'm only seeing small non signficant adjustements to ETA, not that I'm surprised because the currents ETAs had steadily improved with the TeleAtlas maps released after 2006.
@cgavula - will check your routes later this week, sorry for the delay ! |

No concerns.
My guess is that the error will still exist since the maps are still incorrect on the Teleatlas web site.
I've placed tickets with Teleatlas to remove the offending (non-existent) streets, but we certainly won't see that change for another map revision or two (at least not until they can verify my claim).

I see in your post you spelled Alion with 2 "l"s. It only has 1 "l". It may be listed as Tillman's Corner rather than Mobile. I know some data sets seem to show it that way.
It's interesting. GM seems to use Navteq maps, which are correct (TA maps are wrong). That route isn't the fastest or shortest, but it is on roads that are rated at higher speeds (40MPM-45MPH) which is proably why they were selected. Can't fault it for that.
The route I mention starts on the same roads, but then you turn right (east) onto Helton, north onto Hillview, east onto Wigfield, north onto Travis (Travis Ext.), then lastly east onto Three Notch Road.
TA version of the maps show a bunch of roads, including Alion, that aren't there in reality. Alion DOES exist but it's really a bit further to the east (where you see another instance of it on TA maps). |

Just completed building the itinerary for our road trip that starts tomorrow (see http://www.gpspassion.com/forumsen/topic.asp?TOPIC_ID=110142 ) using the 920T as well as the 930 with IQR on and with it turned off. In all cases the route includes using toll roads and on the 930, HOV lanes. If the results are accurate it appears like we can save a few hours on the road using IQR:
920T
930 IQR on
930 IQR off

We are about to hit the road so I'll check on the roads used by the various routes later today and report back.
I have done the same with the Nuvi 760. I built the route in 2 sections, one to by brother's home in Ontario and one from there back to our home. The 760 has a problem however, it runs out of internal memory about 3/4 of the way through the return home route calculation. Although I can see the overview map it simply draws a straight line from the last calculated waypoint through the remaining ones to the finish, thereby screwing up any time and mileage readouts.. Not sure how far the 760 would have gotten before giving up if I'd built the itinerary as on large route like I did with the TomTom's.

| The IQR on the 930 is certainly a big improvement over the rest of the TT line. Depending on time of day, the 930 is actually more accurate in it's time estimate than my nuvi760. At off-peak drive times, such as mid afternoon, early mornings, or after evening rush, the 760 is usually closer to the actual time. Where IQ really shines is it's routes, which now more closely mirror the nuvi routing, which has always been good. There have even been a couple of instances, especially rush hour, where the 930 has recommended a slightly faster route. Those trading up to the 730 or 930 from an older TomTom will likely notice some very good changes. Those moving from the nuvi platform would probably notice little improvement outside some specific areas and times, IMHO. |

Just a note that IQRoutes will not be exclusive to TomTom's. Mio, HP, any manufacturer purchasing TA mapsets, will have access to it, and several will likely do so.

That part "the company will launch a new generation of products including maps that carry TomTom's data on driving conditions" ?
Yes it makes sense for TomTom to make the data available to existing TeleAtlas customers, in a way it's the answer to Navteq's Traffic Pattern data that's only been used on the Intellinav iNav v3 AIO as far as I know and not very successfully |

| Great feature once it is broken day by day and time of day. I'm assuming they need more data to make those breakdowns. |

Well, for an old TomTom user it is already a great feature since the unit now calculates the estimated remaining time much more precisely than before.
If they had to break it down into time by day you also have the problem with different seasons and different weather affecting the speed. One smaller road that is fast during summer can be very slow in winter due to snow or ice. |

Sorry I said that wrong, it will be an even better feature once they are able to break it down by time and day.
I'm really referring to rush hour variables but your are correct. Eventually they will accumulate enough data to do this by time and day of year to account for other variables such as the seasons.
Its just a matter of time and continued collection of data.
TomTom is on a roll. |

I was checking a route from my home to another address with which I am very familiar with.
Letting my GO730 with its IQ do its thing it gave the route as 35 minutes for 34.8 km.
I did a "Find alternative" then chose "Travel Via" and selected a certain Hwy (this Hwy did not appear at all on the previous IQ route).
Well to my surprise this route shows as 33 minutes for 35.1 km .
Isnt this a contradiction? i.e. an IQ route should always show as the fastest?
