Challenge Problems
Push your limits with challenges.
Question 1
You observe a traffic stream for one hour with 180 cars passing. Two are moving at 10 m/s, five at 20 m/s, and the rest (173) at 15 m/s. Calculate the time and space mean speeds.
💡 Hint: Use the definitions of mean speeds correctly and set the equations up carefully.
Question 2
If a road can hold a maximum of 40 vehicles but sits at 30 causing slow movement, how does this reflect in a flow-density diagram?
💡 Hint: Refer back to how flow changes with density on that diagram.
