Vehicle Miles Traveled (VMT) was down significantly in 2010 due to the great recession, and gas prices were nearly $4/gallon. People were consolidating trips, using other means, and driving less in general. If these intersections were a grade "E" in level of service (LOS) in 2010, it's a virtual certainty that they're an "F" today (for a simple chart showing each grade and the delays involved, open the CMS report and turn to page 3).
As seen in this FHWA trend above, national VMT dropped significantly in 2010. The result was gasoline "demand destruction", which triggered a surplus resulting in the record low (adjusted for inflation) pump prices we are seeing today. VMT has since returned to where it left off, and has continued to new record highs. Delaware's improving economy, along with Meyer's fierce pro-development stance will further add to it.
