How To Solve Houston's Mobility Problems?

"The ineffectiveness of highway expansion as a sole strategy to combat congestion is the result of a well-documented phenomenon known as "induced demand." As highways are expanded, more people depend on them to make more and longer trips, negating the purpose of reducing congestion. Cities that build fewer roads have been shown to suffer no more (and sometimes less) congestion, travel delay and reduction in travel rates than cities that aggressively pursue road construction."
