Challenge Problems
Push your limits with challenges.
Question 1
A traffic study collected the following speeds and densities: (10 km/h, 150 veh/km), (20 km/h, 200 veh/km), and (30 km/h, 100 veh/km). Use linear regression to find a and b coefficients.
💡 Hint: Focus on organizing your data first before plugging into the formulas.
Question 2
If your calibrated model predicts a free flow speed of 50 km/h and jam density of 250 veh/km, calculate the maximum flow rate.
💡 Hint: Remember to apply the formula for max flow appropriately.
