#2 The value of travel speed is not often what we think

Investments aimed at moving traffic faster have some benefits, but new research suggests increased speeds don’t offer the same benefits as shorter travel times. As societies become more prosperous, speed becomes less important and bears very little relationship to overall time spent traveling.
