I remember once when when driving I was pleased when it occurred to me that I should be seeking to minimise the third derivative of distance with respect to time for the comfort of my passengers. That was the sum total of calculus's contribution to my adult life. Not sure it was worth it.
- ThrustVectoring 10y agoCurves in freeways are designed that way as well - they don't just start turning suddenly, but gradually transition into and out of the curvature.
- 0xCMP 10y agoGood ones at least.
- ThrustVectoring 10y agoDon't quote me on this since I don't remember why I believe it, but I think it's part of the legally mandated design requirements for the US interstate system.
- 0xCMP 10y agoNo I'm sure there are requirements, but sometimes there are also space or budget constraints (I assume) since some curves are definitely safer and easier than others for the same highway (I-95 for me). I wished they were more consistent
- LgWoodenBadger 10y agoOne of my calculus classes in college involved calculating the required spline for a curve of a theoretical portion of interstate in order to meet the interstate requirements/regulations. It was pretty interesting.
