Rounabouts and Status Bar

Mick_1959 · Posted: Wed Mar 11, 2009 4:44 pm Post subject: Rounabouts and Status Bar

Has anyone else experienced an interesting detail when approaching roundabouts in Ireland using DEMO mode (cannot confirm real time).

I am visiting Cork, Ireland on business, and thought I would familiarise myself with the routes I would be using, so ran them in DEMO mode.

As you can see from the screen captures below, when approaching a roundabout, the Staus Bar correctly shows the roundabout and lane to take, but at proximately 400 metres away, the Staus Bar display changes from representation of a roundabout to a wonderful array of arrows.

This does not happen for UK roads, well none that I have driven.

Can you give a location for the junction?

Well it has happened on all roundabouts around Cork I have tried.

However, the one I have give screen captures for is located at: N51.87663 W8.50520

I get arrows like that on large roundabouts where there are a number of possible lanes that could be used when negotiating the roundabout, I think its part of the lane guidance features.

Assuming that 'greyed out' means 'don't, then surely the left hand set of arrows mean take the left lane, don't turn left, don't turn right but go straight on. The centre one means don't take this lane or turn right or double back. The right hand one means don't take this lane and turn back. Confused

I have not noticed the direction arrows for a roundabout before, large or small, and the roundabout in question can hardly be considered complicated.

Only thing I can think of, is it is controlled by traffic lights. But that still does not eplain the simple rounabouts it happens on.

It is strange that a simple representation should be changed to something more interesting.

Or did the software engineer get bored and decided on having an adult joke in depicting direction - especially with the two direction figures on right divided by the lane indicator, and one of them being directed to his destination by the left hand direction figure Laughing

The arrows are part of the Lane Guidance feature the device offers, although I would say this is some error/ bug as the display is clearly confusing to say the least - What map version is installed to the unit? - Mike

Could this be another display update lag bug? It should be showing Lane Guidance, but only the status bar actually got updated? (Because the voice interrupts are being given priority?)

Before you brought this up I had never seen (or maybe noticed) this before

Travelling East on M48 you have to leave the motorway at jct 2 due to roadworks and rejoin on other side of the roundabout.

The M25 Junction 6 roundabout near my home does this and I think junction 31 at Lakeside does it too. I'm sure I've seen others as well and they seem to be all multi-lane roundabouts.

Now I'm on 8.302 (vs 8.320) I see this all the time. It is displayed in addition to the full screen Lane Guidance display. But I also see on on other major roundabouts and intersections which do not have the full screen lane display.

A bug or a feature? A "level 2" LG for smaller roads, or a partial display for intersections which have not yet got full LG display?

I can't be sure, but I think I'm also seeing it on intersections where I did see the full screen LG display on 8.320.

So I'm thinking - based on all the other interrupt/delayed processing issues of recent months - that it may be LG but the full screen display isn't making it to the screen.

It's part of the ALG, but seems to only be implemented on some roundabouts (often not very complex ones) and not on others (which are often more complex!)

In your example it is telling you to go in the left lane to go straight on at the roundabout.

In Rick-uk's example it is showing him that he can be in either lane to go right (actually straight on) at the roundabout.

You can turn on/off the main ALG screens in the main menu using the'Hide Lane lane images' option, but there is also a 'Show lane guidance' option in the Status bar options which should disable this if it is too confusing Smile

J8 of the M65 does it as well - hadn't really noticed it before 8.302 and 8.25 maps though!

Same roundabout except this time I am turning left (1st exit).

Approach road (motorway exit slip) has two lanes and road to be taken has only one lane. Hope no-one tries to turn left from the right hand lane
