6.2. Transportation Supportive Index The TSI is a geospatial decision-making tool designed to identify areas in Fort Worth most supportive of new or infill development from a transportation readiness perspective. Its purpose is to guide strategic investments by highlighting locations where infrastructure improvements will yield the greatest benefit in terms of connectivity, efficiency, and alignment with growth objectives. By focusing on areas with existing transportation assets and high development potential, the TSI helps minimize capital and maintenance costs, reduce vehicle miles traveled (VMT), and improve access to jobs, schools, and services.
6.2.1. Methodology & Key Indicators The TSI methodology integrates environmental, infrastructural, and demographic variables into a composite scoring system. Analysis districts were created by aggregating over 5,000 Traffic Analysis Zones (TAZs) into approximately 1,000 standardized districts, creating consistency across all indicators. Each district was evaluated on six key inputs: ■ Population and Employment Density: Higher densities indicate greater potential for efficient transportation service. ■ Trip Density: Based on origin-destination (OD) data for peak travel periods, highlighting areas with concentrated travel demand. ■ Land Use: Incorporates zoning, future land use plans, and designated growth centers to identify areas predisposed to higher- density development.
■ Infrastructure Proximity: Evaluates adjacency to city boundaries and ETJs for future infrastructure integration. ■ Transportation Network: Assesses connectivity and capacity for transit, active transportation, and private vehicles using metrics such as intersection density, ridership, and volume-to-capacity (V/C) ratios. ■ Environmental Constraints: Accounts for parks, floodplains, and water bodies to avoid prioritizing areas with significant natural barriers. Each input was scored from one to five, weighted according to stakeholder priorities: transportation network conditions (50%) and all other factors (10% each). The maximum composite score per district was thirty points.
