Efficiency is one of the four global goals framing sustainable mobility in the Global Mobility Report (GMR). The GMR posits that efficiency is crucial to ensure that transport demand is met effectively at the least possible cost. Because efficiency cuts across multiple aspects of mobility, the GMR arbitrarily defines the scope of the efficiency goal from a macro-economic perspective. Putting in place a transport system that is efficient would mean achieving, among other things: (i) seamless integration across transport modes; (ii) optimal traffic volumes that reduce congestion and delays at borders; and (iii) minimal use of energy for moving people and goods. This would be done at the macroeconomic level—including sub-country, country, region, and world—with all actors optimizing resources such as space and energy, adopting adequate technologies, and making use of regulations and institutional capacity. Given that demand for the transport of goods worldwide is projected to triple between 2015 and 2050, the GMR claims that transport infrastructure and services will have an ever-greater role to play in meeting additional demand. Therefore, addressing inefficiencies must be a priority across the entire system of interconnected roads, railroads, ports, and airports, in any given area.
