摘要：	There is a growing interest in California in smart-growth land- use and transportation strategies designed to provide mobility options and reduce demand on automobile-oriented facilities. This study focuses on models and tools available for use by cities and counties in California for assessing the potential effects of smart-growth strategies. The majority of regional agencies and local jurisdictions in California currently use a version of the Urban Transportation Modeling System (UTMS), commonly referred to as the four-step travel demand model. This study provides a review of the steps in the UTMS process to identify where sensitivity to smart-growth strategies may be limited during the modeling process, and suggests ways that improvements could be made. The greatest degree of modeling smart-growth sensitivity was found among UTMS models used by larger Metropolitan Planning Organizations (MPOs) or Congestion Management Agencies (CMAs). Several larger MPOs in California are also implementing new types of models, such as activity-based travel models or integrated land use/economic/transportation models. Some local jurisdictions also already use advanced models or travel demand models with high levels of smart-growth sensitivity. The report suggests that if local jurisdictions are already using models with moderate to high levels of smart-growth sensitivity, they should continue to enhance their models. However, many local jurisdictions models have very little sensitivity to smart-growth land use or transportation strategies. In such cases, the study suggests the appropriate use of a planning tool and/or post-processing application that incorporates 4D elasticities (e.g., Density, Diversity, Design and Destinations). The report finds that 4D elasticities tools can be used as part of local planning, public participation, and decision-making processes, such as: reviewing major land-use development proposals, preparing updates to city and county general plans and specific area community plans, and during regional visioning and other public participation processes.
