A linear relationship exists between the speed of traffic on an uninterrupted traffic lane and the traffic density (veh/mile), as shown in figure below:
Where : V: mean speed of vehicles (mph). K: average density of vehicles(veh/mi). A, B: empirically determined parameters. At zero density, the mean free speed = A At zero speed, the jam density = A/B
Solution: a. b.
