One explanation for Dallas’ standing as the top car-free big city in Texas is its AllTransit score from the Center for Neighborhood Technology. The score measures a city’s public transit connectivity, access, and frequency.
Dallas has the highest AllTransit score — 6.8 — among the state’s five major cities. Next is Houston, with a score of 6.2, followed by San Antonio at 5.7, Austin at 5.5, and Fort Worth at 3.1.
