The Georgia DOT just got their GA-511 system upgraded and back online, and
they provide an RSS feed for incidents on Georgia roads.  Since it's RSS,
it's really XML, and uses standard fields for various data items.  Here's a
<![CDATA[ GA 400 Southbound<br>N OF KEITH BRIDGE RD ]]>
Vehicle Fire.<br>All lanes blocked.<br>Forsyth Co.<br>Expected clear: today

Tennessee REALLY has it going on, with a great looking XML format you can
see here:
Of course, a "real programer" could do this in three lines of Perl.  I'll
probably do it in 10, but I like to add comments.  :)   Does this seem like
a worthwhile addition to a "tactical information network"?
