WebIt is mostly horizontal and vertical curves and greenshields model equations type questions. Overall - I left the exam feeling optimistic. More on the fail side because I know I flagged a lot more than I expect it to be. I felt like I could fully answer about 65-70% of the exam. Questions on my exam was using formulas I have never seen in my life. WebAn equation can be written for each, usually an ordinary differential equation (ODE). Cellular automation models can also be used, where the road is divided into cells, each of which contains a moving car, or is empty. The Nagel–Schreckenberg model is a simple example of such a model.
