iv. Spot speed study
A linear relationship is observed between speed and density on a certain section of a highway. The free flow speed is observation to be 80 km per hour and the jam density is estimated as 100 vehicles per km length. Based on the above relationship, the maximum flow expected on this section and the speed at the maximum flow will respectively be
