Background

Grant Farnsworth, UDOT’s Region Two Traffic Operations Engineer, requested this analysis on behalf of their region team, who were discussing how to prioritize improvements across different east/west road segments: a select-link analysis on 9000 South, 10600 South, 11400 South, and 12600 South, at points roughly midway between Bangerter Highway and Redwood Road, with a turnaround of about a month.

Overview

At UDOT’s request, this run set performs a select link analysis on the Wasatch Front Regional Travel Demand Model, isolating the trips that travel through four corridor crossings: 9000 South, 10600 South, 11400 South, and 12600 South. A select link analysis traces every trip in the model that uses a chosen link, showing where those trips come from and where they’re headed — which is what makes it useful for understanding how traffic on a specific segment relates to the surrounding travel pattern, rather than just how much volume passes through it.

This run uses the WF-TDM v10x-C70 model with a 2027 roadway network and 2026 socioeconomic (SE) data.

There isn’t currently an indicator on the map showing the specific segment selected for the analysis — it will be the segment with the highest volume on each roadway.

Explore the results

The full interactive results — mapped trip origins and destinations, segment volumes, and corridor-level detail for each of the four crossings — are published as a standalone interactive tool rather than reproduced here:

That tool lets you filter by direction and by select-link group, and to browse the underlying corridor and travel-shed detail interactively rather than through a static report.

Picking a corridor

Once you’re in the explorer, the Select Link Group dropdown is what switches between the four crossings (9000 S, 10400 S, 11400 S, 12600 S) — select one, or “All Groups (Total)” to see combined volume across all four.
