Master Transportation Plan Medium-Term Modeling Analysis
3.6 Key takeaways for system performance and project prioritization • Critical corridors remain central: I-35W, I-820, and I-20 continue to carry the heaviest volumes across all scenarios, underscoring their importance for regional mobility. • Scenario 1 improvements strengthen connectivity: By diverting trips from local streets to higher-capacity facilities, Scenario 1 reduces stress on secondary roads, especially in the Northeast and Southwest quadrants. • Scenario 2 provides incremental gains: Additional connectivity further reduces volumes on secondary facilities and improves overall speeds, though congestion hotspots persist. • Localized trade-offs emerge: While principal arterials experience added pressure from new connections, freeway facilities benefit from reduced LOS F mileage . • Overall system efficiency improves: Both Scenario 1 and Scenario 2 scenarios outperform No-Build and Baseline in terms of travel time index, speeds, and LOS distribution, suggesting a clear benefit to advancing these projects. • Need for targeted future investments: Remaining congestion along I-35W, near the airport, and in downtown Fort Worth indicates that complementary infrastructure strategies will be needed to sustain long-term performance. 4 Intersection Operational Analyses In addition to the systemwide travel demand modeling and medium-term analysis summarized in Section 2, detailed intersection operational analyses were conducted at two critical locations within the study area: • Old Denton Rd & Westport Parkway, and • Chapin Road & Chapel Creek Road These intersections represent “pressure points” where projected growth, land use intensity, and freight activity converge, and where deficiencies are expected to become most evident under future conditions. While the regional model provides a corridor-level view of future volumes, intersection analysis supplements this by translating forecast volumes into lane-level turning movement operations. Together, these analyses support recommendations in the Transportation Investment Program (TIP) that reflect both systemwide capacity needs and localized operational challenges. Each intersection analysis followed a consistent methodology: • Forecast Development : Directional average daily traffic (ADT) volumes for 2026, 2036, and 2050 were obtained from the NCTCOG travel demand model. Replica Network Link Analysis provided turn movement proportions based on 2024 baseline conditions, assumed to remain stable for forecast years. A K-factor of 10 percent was applied to derive peak-hour turning movement
