The new Subregional Modeling Tool (SMT) greatly simplifies the creation of subregional models. The SMT fully automates the development of all aspects of a subregional model. The Tool is used by transportation commissions, counties, subregions, and cities wishing to create subregional models based on SCAG’s new Regional Model. The new Tool promotes model consistency between the Region’s various model agencies and greatly reduces the cost and effort required to create subregional models.
