  If you spend any time at your car this summer, you probably sad in this traffic, maybe you are in jam right now.

If so, study another coming issue of phyical review letter might help pass the time.

According to science, building new road woundn't make traffic any lighter, could even make things worse.

What might help though is shutting a few streets down. Imagine that are two roles that take is work.

One alone wide free way and the other short wite bridge. 

 In this example, everyone's drive type would be minized if half of the moters took the bridge and others have on the high way.

of course. nobody care about the minize in the collect of commute. every driver wants to get the first.

So, some of the high way driver will switch to the bridge thinking that would be quicker.

When the bridge backs up, some one have the high way. The upshot of back and force is that everyone's commute takes longer.

In real life up to 30% longer of the physis find.

The solution they said is closed of a few carefully selected avenue to limite that two and flog.

With less choice and less choas everyone moves faster. Sounds kinds of intutide but it could be wouth to try.


[The following is an exact transcript of this podcast.]

If you spent any time in your car this summer you probably sat in some traffic. Maybe you’re in a jam right now. If so, a study in an upcoming issue of Physical Review Letters might help pass the time. According to scientists, building new roads won’t make traffic any lighter. It could even make things worse. What might help, though, is shutting a few streets down.

Imagine that there are two routes that take you to work: one a long wide freeway and the other a short, narrow bridge. In this example, everyone’s drive time would be minimized if half the motorists took the bridge and the other half the highway. Of course nobody cares about minimizing the collective commute. Every driver wants to get there first. So some of the highway drivers will switch to the bridge, thinking that’ll be quicker. When the bridge backs up, some will head for the highway. The upshot of all this back-and-forth is that everyone’s commute takes longer—in real life, up to 30 percent longer, the physicists find. The solution, they say, is to close off a few carefully selected avenues to limit all that to-and-fro. With less choice, and less chaos, everyone moves faster. It sounds counterintuitive. But it could beep worth a try.
