Big-City Transportation Systems Too Complex For Our Brains?

A bunch of physicists and mathematicians recently teamed up to study our ability to comprehend big-city transportation systems. The results, as you might imagine, are not very encouraging.

After analysing the world's 15 largest metropolitan transport networks, the researchers estimated that the information limit for planning a trip is around 8 bits. Using journeys with exactly two connections as their basis (that is, visiting four stations in total), the researchers found that navigating transport networks in major cities آ– including London آ– can come perilously close to exceeding humans' cognitive powers.
