Earlier this spring, two national organizations that study public transportation teamed up to create a giant map showcasing how hundreds of cities' transit networks cater to different neighborhoods.
It also ranked cities on a ten-point scale based mostly on the accessibility of routes, along with how effectively they get people to where most jobs are located. Houston scored a 6.9, compared to Chicago's high-ranking 9.1, Philly's 8.9 and San Antonio's 5.7, for example.
