Myror i rusningstid
I Nature-artikeln Ants avoid traffic jams berättas om myrors lösning på trafikstockningar: knuffa undan andra myror på en annan väg.
When it comes to traffic congestion, ants prefer the no-nonsense approach - they barge others out of the way, forcing them to take an alternative route.
...
[P]roblems can arise when too many ants try to use the route, says Vincent Fourcassié of the Université Paul Sabatier in Toulouse, France. His team found that ants are surprisingly good at avoiding congestion, simply by shoving each other off the main highway and on to back streets.
Det finns praktisk nytta med dessa studier.
Similarly simple rules could be used to manage the flow of data through networks such as telephone systems, says Peter Bentley, a computer scientist at University College London. "Congestion is a big issue," he says. "You have to work out the best route for data."
Many scientists rely on the behaviour of ants or other natural systems to give them clues as to how to design computer systems that avoid overcrowded networks.
Trots detta ska vi vara snälla mot varandra i trafiken.
