Why Does the "hourvmtfraction" Table in the MOVES Default Database Include Fractions for roadTypeID 1 (off-network)?
See More Frequent Questions about MOVES and Related Models. The original concept for MOVES assumed that there would be some vehicle miles traveled (VMT) not accounted for in the other four road types. This remaining VMT would be accounted for in roadTypeID=1. As the model developed, it was decided that…
