Zumo/Map source route time difference
- Thread starter dave hendy
- Start date
Well, let's see.Realy? And what ZUmo do you have??
I suggest you ask dave a copy of his route an try it out yourself..
Earlier you said roadspeeds are set to USA maximums. No .... They .... Are ..... Not!
You then went on to say that A USA "Highway" can even be a dirtroad! A Highway in the States is a main road, one linking towns or cities. I'm sure you can find one example to support your position, but I doubt it's common and humbly suggest that this has little to do with Dave's problem. Note that Mapsource breaks down Highways into sub-categories.
Finally you mentioned that The Zumo actualy "learns" from its Master. Yes, well, so does the 2610. But can this explain an error of 2.5 hours in Dave's route calculation? I think not. Minutes, maybe.
There's little point in asking for a copy of Dave's route, since the error may only be apparent on the Zumo.
I am, however, interested in your response to John's theory; when you say the Zumo 'calculates' the route, what exactly do you mean? On pre-Zumo units, a downloaded Mapsource route would not re-calculate unless the map data was different. In this instance, the GPS unit would offer a re-calculation or draw straight lines between waypoints.

Screenprint from mapsource settings
Speed in KM/h
Speed in Mp/h
It is very UNlikely that these speeds match the speeds of similar roads in the rest of the world. I.e. in the Netherlands there is in general only one "Highway" and certainly not a catagory "other highway"
If Dave's route has a lot of what Mapsource thinks are "other highway's" but he can in fact drive much faster then these settings, why could this not be --A-- (not the) source of difference then?
Indeed: On my holliday in the US, we traveled about 50 miles on a "highway" that was that dirtroad. Ok, maybe it was the only one in the US..
As to your final remark. I understand that you do not have a Zumo. When you do, you can easely mistake the zumo's proces after connecting. It say's "calculating" in the screen. What it does is it just converts the Mapsource data to .gpx dat, but exactly on the mapsource roads.
In that way it does not recalculate that it holds in account the roadsettings and avoidences as they are in the zumo. Only after you force it to recalculate or (when driving) you have set it to recalculate when going off route, it will do so and make a new route based on its internal settings.
Offer: If Dave is willing to send me his route by email, I am willing to look closer to it and even post a few piccy's here to see for all.

Since I was playing with my Norway routes anyway (for an upcomming holliday) I paid extra attention to this phenomena.
Home (Netherlands) to Kiel Germany.
Route settings all the way to max highway / fastest etc
In MS as in the Zumo
Distance 583 km
Time
Mapsource : 5:46
Zumo after importing as well as after forced recalculation: 4:52
Independent internet routeplanner: 5:17
After adjusting some time settings in Mapsource: New time 4:58
So go figure it out

I have mapsource V9 with all updates done except some betta update I have seen recently. I have a Zumo 550 purchased from E-Buyer with (as far as I am aware) full European mapping.
I will have a go at emailing one of the routes (I will pick one with the biggest time difference) when I get home from work. Do you want the mapsource version or the GPX version I had to do to put on my SD card?
I will let you know my speed settings although I changed them to some posted at the weekend.

Mapsource says its version 6.12.4. The maps zoom into 80ft so they must be the full version.
My speed settings in mapsource are 67/55/45/30/20 mph.
My avoid's are set for unpaved roads, U turns and carpool lanes.
My calculation setting is for faster time.
Attached is one of the routes its 154 miles. Mapsource says it will take 6hrs 4 mins. The Zumo says 3hrs 43 mins!

I will have a go at it.
At what position exacltly is your slider in the routepreference set?
Favour set max to highway or to the other way ?
Your Mapsource version is ok.

Ok Dave.
This is what I have found.
First I checked the route for any anomoly's like off road waypoints and things like that. Well, your route is absolutely 100% fine!
Second I duplicated your route to have 1 original and a copy (you can do that within mapsource: rightclick on the selected route in the "routes" tab and select "duplicate"
I then checked your settings and copied that (using default speed settings)
Still within Mapsource, the time changed from 6:04 original to 4:28 !!!
After this I checked the route in detail to see if there are any "shortcuts" or different roads now: There was non. The route is exactly the same.
So my first conclusion (guess) would be that this route probably comes from another source or older version of Mapsource. That 6:04 time that was embedded is not correct to start out with.
Next step was to speed up the settings in Mapsource. That gave a time estimate of 4:11.
As a last test I loaded both routes in my Zumo: Original & copy gave both the same time of 3:41.
So the gap has been narrowed down to half an hour. This COULD be explained by my own units internal learned speed settings.. (I do drive fast , --or at least 2 minutes faster then you ;-o --- )
I suggest you follow the same steps and recalculate your routes in Mapsource. Check if there are any small differences in the route. Correct them and then upload them in your own Zumo. See what that comes up with.
Good luck!

I have planned these routes from scratch (using the road book) over the last 2 weeks or so. As I have only had the Zumo since the 14th July I have only ever had/used this version of mapsource so not sure how it has come from an older version.
I will have a play with copying the route and see what happens. Thanks for your time and effort

I too got a Mapsource time of 4:28. However, when I first re-calculated, I got some strange detours & odd times. At one stage, Mapsource had defaulted to Bicycle timing. Try re-selecting Car/Motorcycle as the vehicle.
Oh, and try de-selecting 'Avoid U-turns'; hairpin bends can sometimes be recognised as u-turns.
All was going well as I started to recalculate the routes I have planned with my newer speed preferences. The first 2 routes dropped by about 1 hour each then the third increased by over 1.5 hrs
When I looked at the map of this route it had added an extra excursion
So at this point I have decided to give up and go by an average of the 2 times and will see how it goes on holiday
I doubt whether I will have time to experiment much before I go away.
At the weekend I may copy the route with the biggest time difference back from the Zumo and follow the route in detail in mapsource to see if it has changed from when I planned it.

As a final suggestion (regarding your time left) I would say; set your recalculation off in the zumo, and simply ride your routes.
The ETA in the Zumo is probably the most accurate. And you know in real life you get to meet unsuspected delay's or extra stops anyway....
Just enjoy them :cool

Another thing to check is the custom avoids - I found my 2610 was finding all kinds of "interesting" shortcuts in the Pyrenees because the unpaved highways avoidance box wasn't ticked. Fine on a GS, but not on a K1200S

This is a must if you ride through mountain passes. What we call hairpin bends the Yanks call a U turn.
Following our trip in September (Yes I know its December now!!) I would like to report back that the times the Zumo calculated were the most accurate by far.
Turning the U-turn avoidance off helped any route planning although some of the tight u-turns did seem to confuse the Zumo from time to time, with it saying to turn round until it sorted itself out
I am still unsure why there's a difference in the times between the computer and the Zumo but hey I can live with it.
My only real gripe with the Zumo is the lack of volume when conected to my autocom
