Ants also commute -between their nests and sources of food.The survival of their colonies depends on doing this efficiently. When humans commute,there's a point at which cars become dense (enough to slow down the flow of traffic,causing a jam.Researchers wanted to know if ants on the move could also get stuck.So they regulated traffic density by constructing bridges of various widths between a colony of Argentine ants and a source of food.Then they waited and watched,trying to find out at what point they were going to have a traffic jam. But it appeared that that never happened.They always managed to avoid a traffic jam. The flow of ants did increase in the beginning as ants started to fill the bridge and then levelled off at high density.But it never slowed down or stopped,even when the bridge was nearly filled with ants. The researchers then took a closer look at how the behaviour of individual ants impacted traffic as a whole.And they found that when ants sense overcrowding,they adjust their speeds and avoid entering high-density areas,which prevents jams.Their behaviour may be promoted by pheromones,chemicals that can tell other ants where a trail is.The ants also manage to avoid colliding (with each other at high density,which could really slow them down. Can ants help us solve our own traffic problems?Not likely.That's because when it comes to getting from point A to point B as fast as possible,human drivers put their own goals first.Individual ants have to be more cooperative in order to feed the colony.But the research could be useful in improving traffic flow for self-driving cars,which can be designed to be less like selfish humans-and more like ants. 语篇解读：研究发现，蚂蚊在往返于巢穴和食物源之间时，如果感觉到过度拥挤就会 作出调整以避免交通堵塞。它们的行为可能是由它们体内的信息素推动的。这项研究在改 善自动驾驶汽车的交通流量上可能
