If London is more spread out than Paris, why don't Londoners travel more than Parisians?

摘要

London and Paris are two megalopoleis with much in common but one main distinguishing feature, their densities: London is considerably more spread out than Paris. Since so many of their other features are similar, such as their population, their household structure, their employment structure, their household incomes, their car ownership levels, their public transport systems, their road networks, this separating characteristic allows a good test of some of the current theories about the relation of travel to land use, and about the influence of travel on the expansion of cities and especially about the changing relation between the central city, the inner core and the outer ring.
