Zusammenfassung:This study demonstrates the potential value, and difficulties, in utilizing large‐scale, location aware, administrative data together with urban modeling to address current policy issues in a timely fashion. We take advantage of a unique dataset of millions of odometer readings from annual safety inspections of all private passenger vehicles in M etropolitan B oston to estimate the vehicle‐miles‐traveled ( VMT ) implication of alternative metropolitan growth scenarios: a sprawl‐type “let‐it‐be” scenario and a smart‐growth‐type “winds‐of‐change” scenario. The data are georeferenced to 250 × 250 m grid cells developed by MassGIS . We apply a greedy algorithm to assign Traffic A nalysis Z one ( TAZ ) level household growth projections to grid cells and then use spatial interpolation tools to estimate VMT ‐per‐vehicle surfaces for the region. If new growth households have similar VMT behavior as their neighbors, then the let‐it‐be scenario will generate 12–15% more VMT per household compared to the winds‐of‐change scenario. However, even the “wind‐of‐change” scenario, will result in new households averaging higher VMT per household than the Metro Boston average observed in 2005. The implication is that urban growth management can significantly reduce GHG but, by itself, will not be sufficient to achieve the GHG emission reduction targets set by the State for the transportation sector.
