[Unlock] L5->L2 M4(W)/A4042 Newport

Post by a2bpdq
My Level: 2
Area Manager: No

Would a level 5 or above please unlock these segments to level 2 or carry out the proposed adjustment.

Thanks, Andrew (a2bpdq)

Location: M4(W)/A4042, Newport
Reason: Add Continuous Alternative Road Name
Adjustment Required:
Add Alternative Road Name "A4042 Route Continuity" to these segments Permalink (13 segments)
Sources: Many URs and Frequent Route Testing show that Waze is regularly directing traffic off the M4 at J25 instead of using the filter lane and exiting at J25A.

Justification:

A continuous alternative name along the route we want Waze to use will give that route an advantage over the alternate route which does not have name continuity. The alternate route has already had its name changed to remove any mention of A4042.

Adding the words "Route Continuity" should make it easy for editors to see the purpose of this alternative name.

Following implementation the route will be monitored to see if there is an improvement.

Please try it anyway. I don't think there are any other implications so no harm could come of it.

We've had success with other routing by using this approach of gradual adjustments.

If we don't try it we cannot for sure say it won't work in this case.

Would you kindly take another look at this. I suspect you glanced over it and may not have realised that the purpose of this change was to provide route continuity, not to trigger the detour avoidance mechanism.

Please change the alternative name of the 13 segments to provide a continuous named route off the M4 to the A4042.

Thank you for looking at this issue. I have been monitoring the situation as near 24/7 as I could manage since October 2017. Changes already made have significantly improved the off-too-early problem but it still shows up almost every day. Even one a day is one too many.

I welcome the automated monitoring which will give a baseline against which improvements can be measured. This was not available when I requested it in the past.

Regarding routing, I don't believe senior editors or anyone else outside of Waze HQ knows definitively how routing works and it's down to us editors to test out different methods to see what works best. If they did know then they would have fixed the A40/A417 roundabout issue which, in the end, was fixed by a process of gradual adjustment and testing.

It's not going to work, I'm afraid. For detour avoidance to be triggered, the preferred route must be all the same road type - and this isn't.

Note that you also can't change the final ramp segment to freeway, as that will cause routing problems for anyone with "avoid freeway" turned on.

Providing route continuity has no purpose other than triggering detour avoidance. Waze has no preference at all for a continuous name apart from that.

I presume the problem that's concerning you is users being routed off the M4 at J25 instead of J25A? If that's so, I can see the problem being shown right now on Livemap routes.

We have a system that will actually monitor problematic routes 24/7. I'm going to get that set up for this route so we can get an initial baseline before any changes.

Because of the mixed range of road types, I don't think we will be able to "unprefer" the J25 route. I suspect the solution is going to be a nested roundabout at J25 to completely prevent users leaving at J25 being directed onto the second exit from that roundabout. I'll have a look again once we have some results from the Route Monitor.
