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 possible speeds (in km/h) from the options given below (round off to two decimal places).
The speed-density relation on a one-way, single lane road is shown in the figure, where speed $u$ is in km/hour and density $k$ is in vehicles/km. The maximum flow (in vehicles/hour) on this road is

The figure presents the time-space diagram for when the traffic on a highway is suddenly stopped for a certain time and then released. Which of the following statements are true?

A plot of speed-density relationship (linear) of two roads (Road A and Road B) is shown in the figure.

If the capacity of Road A is CA and the capacity of Road B is CB, what is $\rm \frac{ C_A}{C_B }$?
