Question 1
Given a traffic situation with a jam density of 300 vehicles/km and a free flow speed of 90 km/h, derive the equations for flow and determine maximum flow.
💡 Hint: Utilize both maximum flow principles and Greenshield's equations.
Question 2
Calculate the speed when the density is 60 vehicles/km and the jam density remains constant at 240 vehicles/km.
💡 Hint: Insert values in the correct formula presented in your readings.
