An infographics entry in the New York Times about the distribution of a commute between two arbitrary subway stations in New York City, including a comparison of the distribution of a similar (?) commute by Tube in London. Showing that in most cases, the tail is thinner in London than in New York City. (Warning: the comparison may switch scales.)

Here is a bit of an outlier:

given that the two distributions hardly overlap and still share a similar median commute time!

Statistics on train delays

An interesting item of news on the French public radio: instead of producing rail delays in terms of trains, unions created an alternative indicator per passenger. This sounds fairer, as the impact of delays is felt by every passenger rather than by the train itself! Since most delays occur at rush hour, the consequences are obviously negative for the train companies: only 36% of SNCF passengers arrive on time, while I presume it is much worse for RER passengers.
