Delay-inacurate traffic data

 

confused Lately I receive lots of inaccurate traffic data. I frequently have a red delay of 8-12 minutes on my nuvi 265wt. After checking the "traffic on route" to see details and then returning to "my traffic map" the delay suddenly disappeared from the map. Minutes later when I actually pass the traffic delay area, there was never any delay period. What could influence the delay to pop up?
My 265wt is up to date with the most recent software.

The traffic depends on what

The traffic depends on what reports are received by the company that transmits the FM traffic signals. I often get alerts that don't correspond to anything on the road as I am passing through that spot - and then other times they are accurate. I am not sure how "real" time these reports are and may have some lag that will not show up when there is real heavy traffic but will not show that a slow down cleared up a few minutes later.

In my area I've learned which roads can and can't be trusted, and then adjust my driving accordingly.
