Here is an interesting piece about passenger trends in London’s Underground system since 2001 and how this piece of information helps us better understand how the city's economy is changing (I saw this via Iain Docherty).
One obvious change in passenger patterns captured by this chart shows the notion of 'peak time' has widened over the past fifteen years or so. As the article suggest, this is likely a reflex of some of the changes observed both in the labor market (with the increase in the number of workers that are self-employed and have more flexible time shifts) and in the housing market, where the prohibitive housings costs of London are pushing people farther from the city.
