Varför klustrar sig bussar?
I Nature-artikeln There's chaos on the buses diskuteras problemet att bussar tenderar att klustra sig.
You wait half an hour for an airport shuttle bus, then two show up at once. It's not bad planning, it's chaos, says Japanese researcher Takashi Nagatani of Shizuoka University.
The unpredictability of shuttle-bus services may be inherent in the shuttling process, calculates Nagatani. He demonstrates that the average number of passengers aboard a bus and the distance between vehicles can fluctuate unpredictably, resulting in a less efficient system. Chaos emerges even in a very simple set up of two buses picking up regularly arriving passengers and taking them at constant speed to one destination.
Papret som refereras är Fluctuation of riding passengers induced by chaotic motions of shuttle buses. av Takashi Nagatani. Har dock inte hittat det på en publik sajt.
