Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the formula for time mean speed?
- v = sum(v_i)/n
- v = sum(v_i * q_i)/Sum(q_i)
- v = 1/(n * spacing)
💡 Hint: Focus on how average calculations are performed.
Question 2
True or False: Space mean speed is always greater than time mean speed.
- True
- False
💡 Hint: Review the definitions carefully.

Challenge Problems
Push your limits with challenges.
Question 1
A stretch of road has a time mean speed of 30 m/s with 100 vehicles traveling. If the headway is recorded as 2s, what is the space mean speed?
💡 Hint: Apply definitions and remember how each speed type is derived.
Question 2
In a test scenario, two sets of vehicles with average speeds of 10 m/s and 50 m/s, find the relationship between flow and density given the speed of incoming versus outgoing vehicles.
💡 Hint: You may want to break down speeds by their mean methods and establish flow parameters.
