We propose a theory-inspired measure of the accessibility of a city's center: the size of the surrounding area from which it can be reached within a specific time. Using publicly available optimal-routing software, we compute these "accessibility zones" for the 109 largest US and European...

Road transport will account for a large share of developing countries' future energy demand. This paper reviews the trends in road transport energy consumption in 12 countries (Group of Seven (G7) and BRICS) over the period 1973-2010. We report several stylised facts: road transport energy use...
