In high school math, we learn that average speed is calculated as the ratio of distance traveled to time elapsed. For decades, the thinking behind transportation policies was anchored in this equation: it was believed that the goal was to increase system efficiency, which simply required reducing travel times by increasing average speed. Consequently, the distance variable was deemed less important, since building unimpeded transit systems—such as subway lines, BRT corridors, or expressways—could maintain or reduce travel times over increasingly longer distances.
