107 - Behaviour After Skip

Other Different Route Behaviour - After Skip
A comparison of Saved and Imported Routes

Pic 1 - A Typical Route - Demo The bike is located at a roundabout. The plotted route takes the second exit - straight on - and passes through a shaping point at a cafe in the small village.

I don't want to visit the cafe, so I take the 3rd exit which is a 3-lane by-pass. The second shaping point is located after the point where the village road and the by-pass meet.

U-turns are permitted for these illustrations (but it made no difference to behaviour) - but the by-pass is a fast 3-lane road. The XT knows this and it will not be tempted to request a U-turn here.

A Via Point at the top right is badly positioned in the middle of a field. This will be part of a later test.










Pic 2 - Normal Behaviour - A 'Saved' Route

I have just taken the the third exit at the roundabout. The XT immediately recalculates the route to the next junction and heads me back to the shaping point at the cafe in the village. It will then do a U-turn and take me to the road I have just left and then to the next shaping point on the A65.




Pic 3 - Imported Route - After Skipping a point earlier in the route

After Skip was pressed, the XT recalculated the entire route - although there is no visible difference in the roads that it has chosen. However, the behaviour of the routing is now different. The screen shot was taken with the bike in the same position as in Pic 2. The route has recalculated, but because I have ignored the route to the shaping point - the shaping point has been completely removed from the route.




Pic 4 - Mis-Placed Via Point

All Zumos will try to take you to Via Points locations - even if there is no road. It will navigate on roads as close as possible and then plot a straight line (sometimes dotted) and issue an instruction like (say) 'Navigate Off Road'.

> But what else can it do - that's where the Via Point is placed. Via Points are traditionally - 'must visit' locations.




Pic 5 - Imported Route, Skip Not Pressed - Ignore A Turn towards a Via Point

This shows the the XT screen after I have passed the turn to the Via point. It is doing two separate things - Asking me to U-turn, and asking if I want to skip "06 Off Road Via".

I ignore both requests and carry on riding. The XT keeps repeating the above sequence. The brighter magenta line is the section that the Zumo is navigating - and that is behind me - going back for the Via Point. As far as the XT is concerned, I am riding the wrong way and getting further from the end point. Repeated U turns - but this is not RUT behaviour.




Pic 6 - Imported Route - Skip Pressed Earlier

This is the same situation as above - Pic 5 - identical circumstances, except that I skipped a point earlier in the route, so the route was recalculated. The route now shows different behaviour:
  • Within 5 seconds of ignoring the route to the Via Point, the screen changed to that in Pic 6.
  • No Info. No Request to Skip.
  • The route ahead is now a bright magenta - so it is the current section.
  • The magenta line behind me has disappeared (compare Pics 2 and 3). It is as if the XT has calculated a new route from my current position through the remaining route points.
  • The Via Point flag has been removed from the route
