TSPLOST supporters will tell you that Dallas and Denver will steal business from Atlanta because of our traffic problems. TSPLOST supporters will also tell you that Dallas and Denver have a competitive advantage over Atlanta because they have light rail systems. There are also things they won’t tell you.

Both cities have longer average commute times than Atlanta.
