Overview

Version 9.1.1 of the Wasatch Front Travel Demand Model includes key updates across the network, access to opportunity (ATO) metrics, and socioeconomic inputs. The highway network was revised to reflect WFRC’s Amendment #3 to the 2023–2050 RTP, incorporating minor changes to support improved connectivity, mobility, and consistency with fiscally constrained project phases.

The ATO calculation methodology was expanded to include additional travel modes (bike, walk, and drive-to-transit) and now uses distance-based factors tailored to each mode. These updates create a more robust and intuitive metric for evaluating accessibility. Additionally, a secondary household and population forecast was added for Utah County, accounting for growth from 2019 to 2025. This alternate dataset offers users an option to explore how recent development trends may influence future travel demand.
