PRESENTATION DESCRIPTION
The Chittenden County Regional Planning Commission (CCRPC) adopted the VisionEval Regional Strategic Planning Model (VERSPM) to evaluate the impacts of hundreds of policy and planning strategies on the Interstate 89 corridor through Chittenden County. This strategic travel demand model was used to explore multiple policy, land-use, and demographic futures for the CCRPC planning area and surrounding commuter shed for a 2050 horizon year.
The goal of this VERSPM application was to identify investments and strategies that would reduce vehicle miles traveled (VMT) and transportation-associated greenhouse gas emissions within the project area. The VERSPM exploratory model inputs were grouped into six policy “packages” on the following topics: land use and community design; bike infrastructure and transit service; demand management and paid parking programs; pricing policies; income and equity; and electric vehicle adoption and ride-hailing services.
The VERSPM scenario modeling process combined different levels of the policy packages categorically and resulted in 432 unique scenarios. VERSPM users could then filter scenario results to examine general trends through an interactive browser-based tool to “goal seek” scenarios with favorable outcomes; a secondary viewer filtered for specific household characteristics. The VERSPM will inform a follow-on effort to adjust a traditional four-step travel demand model to proxy the VMT reductions in the strategic model.
