Could These Crazy Intersections Make Us Safer?

Everybody knows, that four-way intersections are dangerous. So, what are the alternatives? Head over to The Atlantic Cities Blog to see some interesting proposals for alternative intersections.

“Geometry tells us that the traditional four-way intersection is inherently dangerous. When you plot all of the potential points of conflict on a diagram – and transportation engineers actually do this – it turns out that vehicles have 32 distinct opportunities to collide into one another at the nexus of two two-lane roadways. Cars can crash into each other while merging or diverging from a given lane. Then the worst action happens right in the middle of the interchange, at that perilous point where vehicles turn left across oncoming traffic. […] Engineers concocted some much more intricate intersection designs – and in a few cases actually built them – to improve road safety, save states money and generally stall the inevitable expansion of highways.

    Interesting. But long slabs of concrete taking up more space.
