All concepts →The free flow speed of a highway is 100 km/h and its capacity is 4000 vehicle/h. Assume speed density relation is linear. For a traffic volume of 2000 vehicle/h, choose all the pos...
Relationship between traffic speed and density is described using a negatively sloped straight line. If v_f is the free-flow speed then the speed at which the maximum flow occurs i...
The speed-density relationship in a mid-block section of a highway follows the Greenshield's model. If the free flow speed is $v_f$ and the jam density is $k_j$, the maximum flow o...
The space mean speed (kmph) and density (vehicles/km) of a traffic stream are linearly related. The free flow speed and jam density are 80 kmph and 100 vehicles/km respectively. Th...
