Relationship between Traffic Speed and Density:
The relationship between traffic speed and density is typically represented by a negatively sloped straight line on a graph. As density increases, speed decreases due to congestion and increased interactions between vehicles.
Maximum Flow Speed:
The speed at which the maximum flow occurs is typically denoted as VF/2. This means that the traffic flow is maximized when vehicles are traveling at half of the free-flow speed.
Explanation:
- At lower speeds, the distance between vehicles decreases, leading to a higher density of vehicles on the road.
- As speed increases, the density of vehicles decreases due to vehicles having more space between them.
- The maximum flow occurs when the speed is at VF/2 because this speed allows for an optimal balance between vehicle spacing and flow rate.
Therefore, the correct answer is option C, VF/2, as this speed represents the point at which traffic flow is maximized based on the relationship between speed and density.

Given : Relation between traffic speed and density
∴ Maximum flow occur = Vf/2
Hence, the correct option is (C).
∴ Maximum flow occur = Vf/2
Hence, the correct option is (C).
