Transportation needs are increasing all over the world in developed regions seeking to grow their economies while reducing carbon emissions, and in developing regions where vast numbers of people are, for the first time, accessing global markets. A call for advanced 21st-century networks of roads, airports, shipping facilities, train routes, and public transportation is resounding in cities, small communities, and rural areas alike. Investment in transportation infrastructure is surging globally, with money going into the development of new transportation systems as well as upgrades and extensions of older ones. At the same time, the transformation of the global economy through digitization is driving new patterns of transport for both goods and people.
In both urban and rural communities around the globe, the challenge of moving people and cargo efficiently, safely, and sustainably while providing transportation for all segments of society, not just the wealthy remains a problem begging for new solutions in our increasingly globalized, urbanized, digitized, and environmentally compromised world. Long-established theories and techniques of planners and policy-makers must evolve if they are to help sort out our ever more complex transportation infrastructure. We must embrace new methods and new technologies if we are to build and operate transport systems that deliver these goals while functioning inclusively, to the benefit of all.
