Traffic Volume vs Traffic Capacity
Definition:
Traffic volume refers to the number of vehicles that pass through a particular section of a road during a specific time. Traffic capacity refers to the maximum number of vehicles that can pass through a particular section of a road during a specific time.
Explanation:
The correct statement is option 'B' which states that traffic capacity should always be more than traffic volume. This is because if the traffic volume exceeds the capacity of a particular section of the road, it will lead to congestion and delays. This can cause frustration for drivers and lead to increased travel times, air pollution, and accidents. Therefore, it is important to ensure that the traffic capacity is always greater than the traffic volume.
Spot Speed vs 85th Percentile Speed
Definition:
Spot speed refers to the instantaneous speed of a vehicle at a particular location on a road. 85th percentile speed is the speed at or below which 85% of the drivers are traveling on a particular road section.
Explanation:
The statement that "spot speed is the average speed of a vehicle at a specified section" is incorrect. Spot speed refers to the instantaneous speed of a vehicle at a particular location on a road. The correct definition of average speed is the total distance traveled divided by the total time taken.
The statement that "85th percentile speed is more than 98th percentile speed" is incorrect. The 85th percentile speed is the speed at or below which 85% of the drivers are traveling on a particular road section. The 98th percentile speed is the speed at or below which 98% of the drivers are traveling on a particular road section. Therefore, the 98th percentile speed is higher than the 85th percentile speed.
