<font color="blue">"...I won't disagree that Houston has really bad traffic (I lived there for a number of years), however, I'm not as convinced as you that the zoning (or lack thereof) is the major culprit...."</font>
You're likely right. Traffic congestion is a problem prevalent in many American cities and some of it may be zoning related; a good majority of it though is likely associated with general growth in auto ownership, growth in VT (vehicle trips), and VMT (vehicle miles travelled) as a mobile conscious society continues to rely on the private automobile to an increasing degree for general transportation needs. The point I was originally making though was when zoning controls are not in place or when there is quasi-zoning of some degree, then there is the likely potential for transportaion networks to develop in an uncoordinated fashion that does not optimally take into full account potential future traffic growth.
<font color="blue">"...How a number of variables (including zoning) come together paint the picture as to what traffic patterns would/should be. To me, areas such as this are “fuzzy science,” in that while some mathematical models may be relatively accurate in predicting traffic patterns, they’re just that - models. Since there is more than one model out there, it suggests to me that various modelers weigh the variables differently (including zoning). Unfortunately there is no “perfect equation” (such as 1+2=3) when it comes to predicting traffic patterns..."</font>
Exactly....this is what we wrestle with all the time in our traffic models when we try to predict future transportation impacts. Variables are numerous and the magnitude or weight of these variables on known constants are debatable.
Ranchman.....you sure you weren't a transportation planner by profession? You use jargon very similar to what we planners use in the trade. If not, you are a very well read person. I do appreciate your contributions in these forums. /forums/images/graemlins/wink.gif
