Master Transportation Plan Medium-Term Modeling Analysis
• PMLN_AB / PMLN_BA : PM peak hour lane counts in AB and BA directions • OPLN_AB / OPLN_BA : Off-peak lane counts in AB and BA directions • SPLT_AB / SPLT_BA : Speed limits in AB and BA directions A summary of the projects considered, including project names, descriptions, and whether they were coded into the travel demand model (TDM), is provided in Appendix 1. All scenarios were run using the same 2036 demand matrices and consistent land use and control total assumptions. This structured approach enabled a direct evaluation of the operational and mobility benefits associated with progressively higher levels of infrastructure investment. 3.4 Modeling results This section presents the results of the model runs conducted for the medium-term analysis. The discussion focusses on the following key metrics:
• Volume on roadways • Volume to Capacity Ratio (V/C Ratio) • Difference in Volumes between scenarios • Travel Time Index, Speed, and Level of Service (LOS)
A summary of key takeaways is provided at the end of the section, highlighting implications for overall system performance and informing project prioritization.
3.4.1 Volume
Figure 19, Figure 20, and Figure 21 show the AM, PM, and Daily volumes on the network for the Baseline. As expected, PM volumes are higher overall, with I-35W, I-820, and the eastern portion of I-20 carrying substantial demand (~20,000 vehicles) during both AM and PM periods. This highlights these corridors as critical components of the City of Fort Worth’s network. Daily volumes follow similar patterns, reinforcing the prominence of I-820 and I-35W. Figure 22, Figure 23 and Figure 24 present the AM, PM, and Daily volumes on the network for Scenario 1. Compared to Baseline, AM volumes on secondary streets are reduced, reflecting improved connectivity to interstates, FM roads, and other major corridors. These benefits are particularly evident in the Northeast and Northwest (around Saginaw, outside I-820), and in the Southwest near I-30. While PM benefits persist, they are more concentrated within the loop due to increased congestion. Daily volumes show the same trends of strengthened connectivity.
Figure 25, Figure 26, and Figure 27 show the AM, PM, and Daily volumes for the Scenario 2 scenario. Results are consistent with Scenario 1 but with additional reductions on secondary roads. This
