Which of the following is known as design capacity ?
A. basic capacity
B. theoretical capacity
C. possible capacity
D. practical capacity
Answer: Option D
Solution (By Examveda Team)
Option A: Basic capacity This statement is incorrect. Basic capacity refers to the maximum number of vehicles that can pass through a highway under ideal conditions without considering any real-world constraints like traffic flow, congestion, or operational conditions. It is not the design capacity.Option B: Theoretical capacity This statement is incorrect. Theoretical capacity refers to the maximum possible flow under perfect conditions, similar to basic capacity. However, it does not account for real-world factors such as traffic behavior or road conditions, which are taken into account when determining design capacity.
Option C: Possible capacity This statement is incorrect. Possible capacity is often used interchangeably with theoretical capacity, representing the maximum flow under idealized conditions, but it does not represent the real-world design constraints that affect the capacity of a road.
Option D: Practical capacity This statement is correct. Practical capacity refers to the design capacity of a highway, considering real-world conditions such as traffic patterns, vehicle behavior, and road geometry. It represents the maximum number of vehicles that can be efficiently and safely accommodated on the road under typical conditions.
Therefore, the correct answer is Option D: Practical capacity, as it accurately represents the design capacity of a highway considering real-world factors.

If aggregate impact value is 20 to 30 percent, then it is classified as
A. exceptionally strong
B. strong
C. satisfactory for road surfacing
D. unsuitable for road surfacing
right ans is D
" D " is a right answer as explain below:
Basic capacity: The basic capacity is the maximum numbers of passenger cars that can pass a given point on a lane or a roadway during one hour under the most ideal roadway and traffic conditions that can possibly be attained.
Possible capacity: It is the maximum number of vehicles that can pass a given point on a lane or roadway during one hour under the prevailing roadway and traffic conditions.
Practical Capacity: It is the maximum number of vehicles that can pass a given point on a lane or roadway during one hour with creating unreasonable delay under the prevailing roadway and traffic conditions.
Design capacity: it is the practical capacity or a smaller value determined for use in designing the highway to accommodate the design hourly volume.
Theoretical Capacity: It is the number of vehicles passing any point in one hour per lane.
Possible capacity > practical capacity
So, Answer: Possible capacity
Ans c
It's practical capacity
Practical capacity is the right answer
Design capacity is the practical capacity or a smaller value determined used for designing highway to accommodate the design hourly volume.
Desing capacity is taken as practical capacity
Practical capacity is right
Only practical capacity
It's a practical capacity.
design = practical capacity
D is right
Basic/theoretical capacity
