Abstract: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.
