Graded A+
1. The primary function of a collector road is to:
A. Provide high-speed long-distance travel
B. Connect local streets to arterial roads
C. Limit access to properties
D. Serve only industrial areas
Answer: B. Connect local streets to arterial roads
Rationale: Collector roads balance access and mobility, linking local streets to
higher-capacity arterial roads.
2. The design speed of a roadway is mainly used to determine:
A. Pavement thickness
B. Horizontal and vertical alignment
C. Number of lanes
D. Traffic volume
Answer: B. Horizontal and vertical alignment
Rationale: Design speed influences curve radii, superelevation, and sight
distance for safe vehicle operation.
3. Which factor most influences stopping sight distance (SSD)?
A. Lane width
B. Vehicle speed
C. Shoulder type
D. Pavement type
Answer: B. Vehicle speed
Rationale: Higher speeds require longer distances for perception, reaction, and
braking.
,4. The main purpose of superelevation is to:
A. Reduce vehicle speed
B. Counteract centrifugal force on curves
C. Improve sight distance
D. Increase friction
Answer: B. Counteract centrifugal force on curves
Rationale: Superelevation tilts the pavement to help vehicles safely navigate
horizontal curves.
5. The Highway Capacity Manual (HCM) defines Level of Service (LOS) based
on:
A. Pavement type
B. Traffic flow quality
C. Accident frequency
D. Vehicle mix
Answer: B. Traffic flow quality
Rationale: LOS measures operational conditions like speed, density, and delay
to assess traffic performance.
6. The design hourly volume (DHV) is generally what percent of the Average
Daily Traffic (ADT)?
A. 10%
B. 30%
C. 50%
D. 70%
Answer: B. 30%
Rationale: DHV is often taken as the 30th highest hourly volume in a year for
design purposes.
7. The main function of highway drainage is to:
A. Reduce pavement cost
B. Improve aesthetics
C. Prevent water accumulation and damage
D. Reduce friction
, Answer: C. Prevent water accumulation and damage
Rationale: Proper drainage prevents weakening and failure of pavement and
subgrade.
8. Flexible pavements are preferred over rigid pavements because:
A. They are stronger
B. They distribute loads over a wider area
C. They are more rigid
D. They require more maintenance
Answer: B. They distribute loads over a wider area
Rationale: Flexible pavements bend under traffic loads, spreading stresses to
the subgrade.
9. Resilient modulus in pavement design refers to:
A. Permanent deformation under load
B. Temporary elastic response of the subgrade
C. Asphalt shear strength
D. Concrete compressive strength
Answer: B. Temporary elastic response of the subgrade
Rationale: Resilient modulus measures the elastic response of soil or pavement
under repeated loads.
10. A roundabout is safer than a traditional intersection because:
A. Speeds are higher
B. Traffic signals control flow
C. Conflict points are reduced and speeds are lower
D. Pedestrian crossings are eliminated
Answer: C. Conflict points are reduced and speeds are lower
Rationale: Roundabouts reduce angle and head-on collisions by lowering
speeds and eliminating perpendicular conflicts.
11. Geometric design of a roadway includes:
A. Horizontal alignment
