Abstract:Communities throughout the U.S. are pursuing land use and transportation plans that locate ; high density, mixed-use development near high quality rail and bus transit service. The ; objective of these plans is to meet important community goals, such as economic development, ; reduced congestion, greater transportation choice, and improved public health. These plans ; may also be critical to managing the growth in passenger travel necessary to meet greenhouse ; gas (GHG) reduction goals and avoid the most devastating damage to human and natural ; systems from climate change. Increasingly, however, there is concern that these plans may ; have unanticipated consequences that could undermine the well-being of low-income groups ; and GHG reductions. This study uses a spatial economic model developed for the Sacramento ; region (Sacramento PECAS) and an advanced travel demand model to simulate a land use and ; transportation plan from 2014 to 2030. We examine the plan’s effect on population, housing, ; rents, and consumer surplus by location and income class over time and changes in travel ; behavior. We use the EMFAC emissions model with the travel behavior output to measure ; changes in on-road vehicle GHG emissions. In addition, a lifecycle assessment model uses the ; economic activity output from the simulated scenario to estimate changes in upstream and ; downstream GHG emissions.
