Assuming that a constant travel-time budget, geographic constraints and short-term infrastructure constraints persist as fundamental features of global mobility, what long-term results can one expect In high-income regions, {{U}} (41) {{/U}} NorthAmerica, our picture suggests that the share of traffic {{U}} (42) {{/U}} supplied by buses and automobiles will decline as high-speed transport rises sharply.

In several developing regions, most travel {{U}} (50) {{/U}} in 2050 will still be devoted to nonmotorized modes.Buses will persist {{U}} (51) {{/U}} the primary form of motorized transportation in developing countries for decades.{{U}} (52) {{/U}} important air travel becomes, buses, automobiles and {{U}} (53) {{/U}} lowspeed trains will surely go on serving vital functions.{{U}} (54) {{/U}} of the super-rich already commute and shop in aircraft, but average people will continue to spend most of their travel time on the {{U}} (55) {{/U}}.
