Even the best of the models used by MPOs, rarely account for the impact of highway expansions on land use! This is a problem!
"study of models.. found underestimation of induced VMT up to 102% and overestimation of reductions in travel time up to 236% when feedback to land use was not included"

New UC-Davis primer on induced demand:
"Studies arrive at the same conclusion: the long-term elasticity of VMT w.r.t. lane miles centers around 1.0. This means that a 10% increase in lane miles is likely to increase VMT by 10% in the long run (within 3 -10 years)."
