Abstract
We need to be much more aware of trends that surround us—trends in population distributions, demography, public tastes and preference, and economic behavior—as we seek to respond to public needs for infrastructure and services. It is easy to miss broad sweeping trends when in the middle of them. So it is that the broad trends affecting national transportation patterns and growth have not been recognized. Awareness of the social and economic trends that will shape the size and character of future transport demand should be heightened. This article examines some of the past trends missed and their effects. It looks at emerging trends that will be forces of change in the future that cannot afford to be missed. It also suggests a list of investment directions that derive from these trends.
