I understand that traffic jam information is obtained by the navigation systems, among other things, by the movement of mobile phones on the road, this information is provided by the telecom providers for this purpose, I think.
So it seems that this information is not properly interpreted by the MyRoute app. TomTom seems to process this in a different way, so that you do get reliable traffic information.
Every app has its own source for Traffic information. Google is the gold standard for providing the most current/comprehensive data. Apple is slightly behind but catching up. The Tread app (Zumo XT2/XT3) uses Garmin’s traffic network, which is actually pretty accurate. There are others, but unfortunately there isn't a universal source for all to tap into.
MRA uses HERE provided traffic information. Like most things HERE, you're not getting the highest quality experience relative to the other map providers. Supposedly HERE traffic reporting is going to get better in an upcoming MRA release. Time will tell.
