Definitions & Glossary Access Management
Capacity (Macro-Level) The maximum volume of traffic a roadway can accommodate under specified operating conditions. Capacities in this document are associated with LOS-E thresholds and provide a starting point for cross-section assignments. Comfort Threshold A volume threshold below the theoretical LOS-E capacity that reflects practical operating conditions in Fort Worth, including driveway spacing, signal operations, multimodal activity, and corridor context. Comfort thresholds guide cross-section decisions in the Master Roadway Network. Collector (Major / Minor) Roadways that connect local streets to the arterial network and balance access and mobility. ■ Major Collectors are mapped in the Master Roadway Network and carry higher volumes with more limited access. ■ Minor Collectors are not mapped and are established through subdivision design. Cross-Section The adopted arrangement of lanes, medians, sidewalks, shared-use paths, buffers, and other elements within the right-of-way. Cross- sections define the ultimate build-out condition for each roadway segment in the network.
Cross-Section Assignment The specific cross-section applied to a roadway segment based on functional classification, forecasted demand, operational considerations, and multimodal needs. Cross- section assignments determine right-of-way preservation requirements. Dedication (Right-of-Way Dedication) The requirement that property owners convey right-of-way to the City through the subdivision or development process to achieve the A hierarchy that groups roadways based on their intended role—mobility, access, and connectivity functions—within the transportation system. Functional classifications include freeways, arterials, collectors, and local streets. Grade Separation A roadway or railroad crossing in which travelways operate on different vertical levels (e.g., overpasses, underpasses). Grade separations improve safety and mobility and may require larger right-of-way footprints. Interim Cross-Section adopted ultimate cross-section. Functional Classification A temporary roadway configuration constructed before the ultimate cross-section is built. Interim cross-sections must preserve the full right-of- way and not preclude future expansion.
A set of strategies used to regulate the spacing, location, design, and operation of driveways, medians, and intersections to preserve mobility, safety, and the functional integrity of roadway corridors. Administrative Adjustment A minor modification to the adopted Master Roadway Network or cross-section assignment that may be approved by City staff without City Council action. Administrative adjustments are limited to changes that do not materially affect right-of-way needs, functional classification, or mobility outcomes. Alignment The horizontal and vertical location of a roadway centerline. In the Master Roadway Network, alignments represent planning-level centerlines that may shift during engineering design. Arterial (Major / Minor) Roadways that provide mobility across large portions of the city, connect major activity centers, and carry higher traffic volumes than collectors. ■ Major Arterials emphasize mobility and longer-distance travel. ■ Minor Arterials balance mobility and access within subareas of the city.
