2. Vehicle miles of travel (VMT) a key measure of transportation sustainability The most sustainable areas are those with the least vehicle miles of travel (VMT) “…reducing vehicle miles traveled (VMT) is an official goal of the U.S. Government policy” In 2011, SA2020 set a goal of a 10% reduction in the 2007 value of 21 miles/day/capita by 2020 In 2016, SA Tomorrow Sustainability Plan set a goal of reducing VMT from 22.4 miles/day/capita in 2013 to 16.5 in 2040 2 Black, William R.

3. VMT Urban Heat Island Impact beyond greenhouse gas emissions Cities are warmer than surrounding countryside due to impervious cover and anthropogenic heat San Antonio temperatures are increasing - impacting human health and the economy Auto-oriented development pattern creates more impervious cover 47-62% of anthropogenic heat in the summer is from VMT 3 http://www.climatecentral.org/news/sizzling-summers-20515#dangerdays www.vtpi.org/landuse.pdf Sailor, David J., and Lu Lu.
