Is traffic information used to optimize navigation route?

[james203]

Here's a Garmin website that has information on the XMTraffic coverage:

And for those of you who don't get it...I am NOT saying that the Genesis unit is from Garmin....only that the Garmin site has this information. ;=)

I think the area served for a metropolitan area by XM Traffic can vary; for example I live in the DC/Baltimore area, so the area covered is pretty huge. I can get traffic reports as far east as Havre de Grace (NE of Balto) and as far south as Quantico.

I have noticed that it only gives my traffic data for interstate highways; other major highways like US 50, the Dulles toll road, MD 100, the Balto/Wash Parkway and others don't have traffic data displayed.

Mine was like yours, in that it only gave the data for Interstates, in major cities, like Dallas. The "Other" major highways did not show the data.

NOW, I not only have it in the Interstates around Orlando, but I also have it on "Other" major roads, like US-441 between Orlando and Leesburg. Will see where else I get it when I head North in three weeks.

After studying the XM Coverage Map, it appears that all roads that XM Traffic covers will give an indication if there is a "Traffic Incident", however not all roads will give "Traffic Flow" problems. The traffic flow problems seem to be given only for major highways (for example I-95 in the Baltimore area).

I have an 09 with tech. to get the re-route around congestion and or traffic, construction, accidents you have to have an active route and your key prefernces on things to avoid (ie traffic/accidents/relatives/..etc.) set in your system.

ive had good fortune with it and without a rack programed, i can still read road info, see accidents, and see other cars with sat nav, and traffic meters
