The McDonnell administration has released its “Transit/TDM Vision Plan” for Northern Virginia. The document projects population, employment and traffic trends for the region through 2040 and recommends investments in transit-oriented  and TDM (transportation demand management) to accommodate the changes.

I’ve got a lot on my plate right now, so I don’t know if I’ll get a chance to review the study or not. A big concern I expressed in a previous post was the utility of making 30-year population, employment and transportation-demand projections based upon past trends that in my humble opinion are not likely to continue on the same trajectory.
