<p class=MsoNormal><font size=2 face=Arial><span style='font-size:11.0pt;
font-family:Arial'>I must admit that, of late, I have gotten lost in the woods
while trying to see all the trees. During these past months I have been
engaged in developing a new TAZ system for the <st1:place w:st="on"><st1:City
w:st="on">Minneapolis</st1:City></st1:place> – St. Paul MPO area that
will both serve the needs of travel demand modeling here at the Metropolitan
Council <b><span style='font-weight:bold'>AND</span></b> provide us with the
information we want from a 2010 CTPP-like product.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:11.0pt;
font-family:Arial'>This new TAZ system is substantially more refined than those
of the past and should result in reasonable travel loadings on our arterial
roadway network. However, certain issues have been raising their knobby
heads regarding zone size that probably will clash with Census Disclosure Board
rules. Does anyone have a reasonable idea as to what minimum population
or household levels a TAZ will need to attain in order to circumvent large
numbers of “blank” cells? I suspect that there is not an
easy, uncomplicated answer but would like to hear one nonetheless.<o:p></o:p></span></font></p>
