Introduction to GreenSTEP, the RSPM, and Related Strategic Planning Models (February 11, 2016)


Date: February 11, 2016

Description: This is the first of three webinars on the GreenSTEP and RSPM strategic planning models. GreenSTEP is an open-source model that was developed at the Oregon Department of Transportation to enable state planners and policy makers to analyze the effects of alternative strategies for reducing greenhouse gas emissions from the transportation sector. The model was designed to address the many factors that affect travel and travel-related greenhouse gas emissions, and yet run relatively quickly so that analysts can run hundreds or thousands of scenarios in order to explore the decision space and test the robustness of policies to different conditions. The RSPM (Regional Strategic Planning Model) was developed from GreenSTEP to model metropolitan areas. These models operate in the middle ground between advanced travel demand models and simpler sketch planning tools. As with advanced activity-based models, GreenSTEP and RSPM model travel behavior using simulated households, but do so by modeling household travel as an aggregate quantity (i.e. annual vehicle miles traveled) rather than as daily tours. On the other hand, these models address a number of factors that are not typically considered by advanced travel demand models such as vehicle powertrains, fuel types, carsharing, and household travel budgets. This webinar will focus on:

  • The motivation for building the GreenSTEP model and the policy issues it was built to analyze;
  • Design overview and major features;
  • Other related models (EERPAT, RPAT) and their differences;
  • GreenSTEP and RSPM application examples;
  • How the GreenSTEP and RSPM models are run; and
  • How to obtain the code and technical documentation for the GreenSTEP and RSPM Models.

The following webinar will go into detail on the design and estimation of these models. The last webinar in the series will describe that new programming framework (VisionEval) that has been developed to facilitate collaboration in the further development of these and other strategic planning models.
