The Traffic Congestion Forecast Map (Factored V/C Ratios) Map has been updated. You can find this app at https://wfrc.org/traffic-vc-map/.
This map provides an estimate of potentially congested areas for WFRC/MAG 2023 Regional Transportation Plan (RTP) scenarios.
The metrics shown on this map are useful for planning and prioritization as comparative measures of travel demand and do not necessarily reflect anticipated conditions at the highest factored V/C ratios.
The congestion is based on volume-to-capacity ratios using the following components:
- AADT forecasts for scenarios as prepared using output from the Wasatch Front travel demand model,
- Volume calculated for various weekday time-of-day combinations using factors from UDOT continuous count stations and the travel demand model,
- Roadway capacities for each scenario as calculated in the travel demand model.
Version 9.0.1 (April 2024) of the travel demand model was used to prepare the data for this web app. MAG Forecasts shown are currently draft.
Additionally, after selecting a roadway segment, there are useful factors and details available by clicking Calculation Details at the bottom of the sidebar.
Corresponding roadway volume forecasts can be found here. Socioeconomic forecasts can be found here.

The following scenarios are included in the map:
| Scenario | Description |
|---|---|
| 2019 Base | Base year of the v9.0.1 model for both roadway and transit network and socioeconomics. |
| 2023 Base | Opening year, or base year of RTP. Roadway and transit network represent existing 2023 conditions. Socioeconomics is forecast for 2023. |
| 2028 TIP | Represents roadway and transit network with Transportation Improvement Program (TIP) funded projects included and matching socioeconomics forecasts for 2028. |
| 2032 Fiscally Constrained | Represents roadway and transit network with RTP Phase 1 Fiscally-Constrained Projects and matching socioeconomics forecasts for 2032. |
| 2042 Fiscally Constrained | Represents roadway and transit network with RTP Phase 2 Fiscally-Constrained Projects and matching socioeconomics forecasts for 2042. |
| 2050 Fiscally Constrained | Represents roadway and transit network with RTP Phase 3 Fiscally-Constrained Projects and matching socioeconomics forecasts for 2050. |
| 2032 SE on a 2028 Network | Represents a no-build scenario where roadway and transit projects include up to the 2028 TIP funded projects and socioeconomics forecasts are for 2032. |
| 2042 SE on a 2028 Network | Represents a no-build scenario where roadway and transit projects include up to the 2028 TIP funded projects and socioeconomics forecasts are for 2042. |
| 2050 SE on a 2028 Network | Represents a no-build scenario where roadway and transit projects include up to the 2028 TIP funded projects and socioeconomics forecasts are for 2050. |
| 2042 SE on a 2032 Network | Represents a no-build scenario where roadway and transit projects include up to the RTP Phase 1 (2032) funded projects and socioeconomics forecasts for 2042. |
| 2050 SE on a 2032 Network | Represents a no-build scenario where roadway and transit projects include up to the RTP Phase 1 (2032) funded projects and socioeconomics forecasts for 2050. |
| 2050 SE on a 2042 Network | Represents a no-build scenario where roadway and transit projects include up to the RTP Phase 2 (2042) funded projects and socioeconomics forecasts for 2050. |
| 2032 Needs-Based | Represents roadway and transit network with RTP Phase 1 Needed Projects and matching socioeconomics forecasts for 2032. |
| 2042 Needs-Based | Represents roadway and transit network with RTP Phase 2 Needed Projects and matching socioeconomics forecasts for 2042. |
| 2050 Needs-Based | Represents roadway and transit network with RTP Phase 3 Needed Projects and matching socioeconomics forecasts for 2050. |
| 2050 Needs-Based MAG | Represents roadway and transit network with RTP Phase 3 MAG Needed Projects and matching socioeconomics forecasts for 2050. |
