Exploring the relationship between speed, safety, and geometry of roadways.
Although many of us are regular drivers, we rarely put much thought into roads. That’s on purpose. If you’re thinking about the roadway itself at all while you’re driving, it’s probably because it was poorly designed. There are so many factors that go into highway safety, many of which are more philosophical or psychological than pure physics and engineering. But to a certain extent, highway design is an art form.
Errata: The graphic at 6:10 shows a spiral into the curve, but not out of it. This implies that the radius is one value going into the curve and another value when coming out of it, which is incorrect except on one-way roads.
