A group of Germans have come up with an ingenious way to prevent jaywalking and entertain pedestrians at the same time. It's called Streetpong, and the idea is already at work in the real world at one lone intersection.


In the US, the four-way-stop intersection is king, with little competition from roundabouts. In Europe, things are reversed, and the roundabout is much more common than four-way-stop intersections. While it has been said before that the roundabout is a more efficient way to handle traffic at a busy intersection, Mythbusters aims to find out the truth.


You might question whether a diamond-shaped yellow sign will make drivers keep an extra eye out for motorcyclists, but if it saves a life, who's to argue?

Once in a while, though, we see the two changing hats, as automakers produce their own brand magazines and magazines build their own kit cars and whatnot. But this collaboration, for better or worse, brings the two that much closer. And if any publication was going to break the mold, we suppose it would have to be Intersection.


It seems most studies of amber lights focus on whether cities are using them to gather revenue. The theory – and let's face it, sometimes the fact – is that the light time is so short that drivers end up tripping the red light camera and getting a fine. Conversely, a new study by the University of Cincinnati and Ohio Department of Transportation has taken a look at how drivers behave when they encounter a yellow light no matter how long it's illuminated.


Every city in the world has at least one intersection that its residents avoid at all costs. My commute back in college, for instance, included a seven-way intersection that contained no right angles. We can all thank our lucky stars, however, that we don't live in Moscow and have to make a left turn from Rosanov Street onto Khoroshev to get where we're going. In order to complete the manuever a driver must go through approximately nine right turns and two left turns that involve swirling around
