1.5.1. Methodology The updated Master Roadway Network, as shown in , requires a consistent, transparent approach for assigning functional classifications to all roadway links. The methodology summarized in Figure 1.2 combines attributes from the 2050 Travel Demand Model with local access characteristics to produce a simplified, planning-scale classification system that aligns with Fort Worth’s future mobility needs. The process consisted of three primary steps: Step 1: Spatially joining new Master Roadway Network links to 2050 Travel Demand Model links Newly developed Master Roadway Network segments were first joined to corresponding links in the 2050 Travel Demand Model. This join allowed each link to inherit key model attributes, including daily volume (DAYVOL) and number of lanes (TOTLANE), that serve as the foundation for classification. Where multiple model links intersected a single roadway segment, the most representative link attributes were selected based on alignment and continuity.
Step 2: Assigning simplified functional classifications using Travel Demand Model attributes Using DAYVOL and TOTLANE values, each roadway segment was initially categorized into a simplified functional classification, Principal Arterial, Major Arterial, Minor Arterial, or Major Collector. These thresholds reflect typical ranges associated with each facility type and align with TxDOT’s Functional Classification System for facilities classified as Major Collector or above. The classification at this stage provides a first-pass, model-informed assignment based on expected traffic demand and lane configuration.
Step 3: Applying quality control based on access characteristics For roadway segments that did not cleanly match Travel Demand Model links, or where volume-based classification conflicted with observed access patterns, additional refinement was performed using access methodology. This included evaluating: ■ Degree of access control (full, partial, or uncontrolled) ■ Connections to freeways or higher-order arterials
■ Corridor continuity and context ■ Adjacent land use and spacing of intersections/driveways
Approximately 80 unmatched or ambiguous links were evaluated through this step to create consistency with both modeled demand and functional expectations.
