Beyond traffic 2045

The first part discusses the major trends shaping our changing transportation system. These include both trends originating from the transportation sector, such as improvements in freight logistics, and external trends impacting the transportation sector, such as population growth and climate change. The second part discusses the implications of these trends for each mode of transportation: highways, transit, pedestrian and bicycle, aviation, intercity and freight rail, maritime and pipeline. The third part presents a description of a baseline future scenarioÑa future that may emerge from the trends analyzed previously. It concludes with a discussion of policy options based on the implications of these trends.
