1.8. Capacity Planning & Cross-Section Framework The Cross-Section Framework translates long- range travel demand, functional classification assignments, and multimodal design objectives into the physical form of Fort Worth’s roadway network. It establishes the basis for determining ultimate ROW needs, identifying appropriate cross-section types, and supporting long- term decision-making for both public capital projects and private development. This framework builds on the functional classification methodology described in the previous section and provides the planning- level structure used to define the future configuration of each roadway segment. It integrates 2050 model forecasts, operational considerations, corridor continuity, access characteristics, and multimodal requirements into a single system for guiding cross-section selection and ROW preservation.
1.8.1. Capacity Planning & Cross-Section Assignment Planning for long-term roadway needs requires a consistent method for relating modeled traffic volumes to the roadway configurations needed to accommodate them. The 2050 Travel Demand Model provides citywide DAYVOL forecasts that indicate where additional lanes, median treatments, access management strategies, or other corridor enhancements may be required.
Methodology Forecasted 2050 volumes were compared initially to planning-level capacity thresholds that reflect Level of Service (LOS)-E operating conditions and are consistent with TxDOT and NCTCOG conventions. These LOS-E values serve as a theoretical upper bound and provide a standardized starting point for relating modeled volumes to cross-section needs. To better reflect how arterial and collector corridors operate under Fort Worth conditions, the City applied a second step using comfort- based thresholds that represent more realistic daily operating ranges. This adjustment acknowledges the influence of access patterns, signal spacing, multimodal activity, and development context, all of which contribute to congestion at volumes lower than the theoretical planning capacity.
