ADS-B traffic operation is similar to other traffic systems, but ADS-B adds additional 

symbology.  The symbols used to display ADS-B traffic are shown in  the table below.  The 
traffic identifier and altitude are displayed below the traffic symbol.  A small up or down 
arrow next to the traffic symbol indicates that the traffic is climbing or descending at 
a rate of at least 500 feet per minute. The vector line that extends beyond the point of 
the traffic arrow is just further indication of the aircraft's track.
