Why Moving People is Complicated: Crash Course Engineering #41

Transportation is a big part of our world and engineers play a big role in making it happen. Today we’ll explore how transportation systems are designed and some things transportation engineers have to take into consideration, like signaling, user behavior, and traffic flow. And, of course, we’ll talk about some of the ways that transportation engineers are trying to improve the systems we already have.
