a) 2
b) 5
c) 3
d) 4
Answer: c
Clarification: There are 3 types of highway capacity defined by Highway Capacity Manual (1950). They are basic capacity, possible capacity, and practical capacity. Highway Capacity Manual was introduced by O.K Norman.

b) Possible capacity
c) Practical capacity
d) Traffic capacity
Answer: c
Clarification: Practical capacity is considered as design capacity. Practical capacity is the highest number of vehicles that can cross a given point in the roadway in an hour when the traffic density does not cause any risk or unwanted delay.

4. Which of the following parameter is not dependent on highway capacity?
a) Class of highway
b) Lane width
c) Number of lanes
d) Gauge width
Answer: d
Clarification: Gauge width is the parameter that is not dependent on highway capacity. Class of highway, lane width, number of lanes, and intersections are the parameters dependent on highway capacity. Development of traffic management measures, geometric elements, and traffic control devices can also be achieved with the aid of studies on highway capacity.

6. Which of the following is not a factor affecting traffic capacity?
a) Lane width
b) Lateral clearance
c) Gradient
d) Traffic control devices
Answer: c
Clarification: Traffic control devices is not a factor affecting traffic capacity. Roadway conditions such as lane width, lateral clearance, gradient, and shoulders affect traffic capacity.

Answer: a
Clarification: Maximum flow rate is the worst 15 minutes of the peak hours. Capacity is the maximum flow rate that the road facilities can bear in prevailing condition.

10. Capacity is measured as a reasonably expected value and not the maximum flow rate observed in the facility. Why?
a) Because capacity at a given location varies from day to day
b) Because capacity at a given location doesn’t vary
c) Because capacity at a given location varies from year to year
d) Because capacity at a given location decreases simultaneously
Answer: a
Clarification: Capacity is measured as a reasonably expected value and not the maximum flow rate observed in the facility. This is because capacity at a given location varies from day to day due to various factors like local driving habits.
