Re: Google Maps traffic data in Waze

Another example of traffic missing in Waze.
Date/time: April 17, 2018 08:10 am UTC+1.
Google ETA: 14 min. Waze ETA: 6 min.
Start/end points.
Here two segments of Scholarstown Rd have the same name on both Google and Waze map, so my theory about different road names may not hold here. But one of the segments has actually two names on Google map, English 'Scholarstown Rd' and Irish 'Bóthar Bhaile Scallart'. May be the Irish one is used to correlate roads.

Road names are different on Google and Waze in this example.

Also I noticed that the exits from M50 are never red/yellow in Waze, even such heavily congested as the one above. It again can be explained by the road name differences in Google and Waze. In Google the exits are unnamed or have name "M50". In Waze all exits have names like "J12 to R113 - Knocklyon, Firhouse".

David, thanks for pushing this issue with Waze HQ.
In the meantime I fixed some street names in Waze (R115 Stocking Ln, R115 Scholarstown Rd) and trying to fix some in Google Maps (St. Colmcille's Way and Ballycullen Rd) to make the names the same and to check whether it fixes the issue with missing traffic. I will re-check traffic in Waze next week.

Agree. Hopefully it's something that can be easily fixed by tweaking some traffic import settings on Waze side.

Unfortunately I don't see any improvements. Waze still doesn't show traffic congestion on those "broken" roads and makes too optimistic ETAs during peak hours. I was hoping that we need to wait for some time until something completely updates somewhere in Waze. But now it's difficult to check the issue because traffic became super light in July and there are no congestions on my daily routes.

But there is another problem that's opposite and that's happening on the same roads. When there is a very light traffic, Waze sometimes makes very pessimistic ETAs as if there was a very bad traffic (without actually showing the bad traffic) and sometimes creates super suboptimal routes (see below). For me it looks like an indication of the same problem, namely Waze doesn't import Google traffic on those "broken" road segments.

BTW, I renamed several segments in Waze and Google to make the names the same but it didn't help.

David, can you please forward the information above to Waze HQ as well?

David, That issue happened on June 22nd 2018 at 8:54am UTC+1.
I see similar issue at the same place every working day at about 9am-9:20am. Waze usually makes ETA about 4 minutes bigger than the actual driving time when the traffic is very light. Sometimes it's even bigger which leads to those wrong detours.
The wrong ETA happens mostly on these segments.
Once I saw the same weird route at about 4am when the roads were completely empty.

Waze sees only a tiny fraction of the traffic congestion that Google Maps sees. So I have a big hope that Waze routing can be improved dramatically here because I already saw such a dramatic improvement in the city I'm from.

Thanks Aleksandr.

I've just emailed our contact in Waze HQ to ask about this. Can you say what city in Russia you're from? Does it appear here, or does it have a much higher population compared to Dublin? It'd be interesting to know whether Waze shows a better view of traffic congestion just because there are more users there.

I'll let you know what we hear back from Waze HQ.
