Acura 2009 RDX Navigation - Manual (Page 22)

22 Navigation System
Getting Started
Real-Time Traffic Display
The navigation screen can display up-
to-the-minute traffic information when
available, including flow (traffic speed),
accidents, and construction on freeways
in more than 40 major metro areas. See
page
129 for a list of the current U.S.
cities that offer traffic information.
The display of traffic flow and incidents
on your map screen is optional and can
be turned On/Off by selecting the
“Traffic” icon on the Icon bar
(see Showing Icons on the Map on
page
65 ).
The current metropolitan areas that have
traffic coverage can be seen on
page
129 . For more current metro
coverage information, go to
www.acura.com/realtimetraffic. This
link offers additional information on
real-time information, including the
following:
• The latest list of metro areas that have
NavTraffic
• Detailed coverage information for
each metro area showing what roads
have traffic speed, traffic icons, or
both
• An XM NavTraffic demonstration
• Frequently asked questions (FAQs)
NOTE:
Real-Time Traffic relies on a satellite
signal. It will not work correctly in
Hawaii and Alaska.
Viewing Flow Data
Traffic flow data is displayed as colored
bands on either side of the freeway (see
Traffic Display Legend on page
21 ).
The different colored bands represent
the average road speeds as determined
by “under-road sensors.”
While driving to your destination on a
road that has traffic flow data, your
route line color is used to display the
traffic flow data. This means that when
the map scale is set to one of the traffic
scales (1/2 through 5 mile scale), your
blue route line may appear as alternating
orange, red, or blue segments (see
Traffic Display Legend on page
21 ).
NOTE:
A blue route line segment on a freeway
can mean one of two things:
• Under-road sensors, GPS probes,
cell phone probes, and other methods
used to collect traffic speed
information indicate free flow traffic.
• The road has no sensors, and traffic
conditions are unknown (they could
be congested).
