1. What is the primary objective of transportation planning?
A. To minimize the cost of transportation
B. To ensure safety for all users
C. To balance traffic demand with available infrastructure
D. To improve air quality
Answer: C) To balance traffic demand with available infrastructure
Rationale: Transportation planning seeks to align traffic demand with infrastructure
capacity, ensuring efficient movement and reducing congestion.
2. Which of the following is not a factor in highway geometric design?
A. Sight distance
B. Pavement texture
C. Roadway cross-section
D. Climate conditions
Answer: B) Pavement texture
Rationale: Pavement texture is related to skid resistance and friction, but it is not part
of the geometric design, which involves layout, curves, and other physical features of
the road.
3. In a transportation system, the 'Level of Service' (LOS) refers to:
A. The environmental impact of the system
B. The safety of transportation infrastructure
C. The quality of service provided to users
D. The economic cost of implementing transportation projects
Answer: C) The quality of service provided to users
Rationale: LOS is a measure of the efficiency and effectiveness of a transportation
system, typically in terms of speed, congestion, and safety.
4. Which of the following is a design parameter for horizontal curves on highways?
A. Stopping sight distance
B. Super-elevation
C. Cross slope
D. Roadway width
Answer: B) Super-elevation
Rationale: Super-elevation is the banking of the roadway on curves to counteract the
centrifugal force on vehicles, improving safety and comfort.
5. What does the term "traffic volume" refer to?
A. The total number of vehicles that pass a point over a given time period
B. The maximum number of vehicles a road can accommodate
C. The number of accidents at a specific location
D. The average speed of traffic on a highway
Answer: A) The total number of vehicles that pass a point over a given time period
Rationale: Traffic volume measures the flow of traffic at a specific point, usually
expressed as vehicles per hour (vph).
6. The primary purpose of the design of intersections is to:
A. Minimize vehicle speeds
, B. Maximize traffic flow efficiency and safety
C. Ensure adequate parking space
D. Reduce the number of lanes on the road
Answer: B) Maximize traffic flow efficiency and safety
Rationale: Intersections are designed to facilitate the smooth flow of traffic while
minimizing conflicts and ensuring safe operations.
7. What is the most commonly used method for designing the alignment of a highway?
A. Lagrangian method
B. Minimum curve radius method
C. Transportation mode analysis
D. Horizontal alignment method
Answer: B) Minimum curve radius method
Rationale: This method is used to determine the minimum radius for curves to ensure
safe vehicle navigation without exceeding frictional limits.
8. In terms of traffic flow, which of the following is most often used to measure
congestion?
A. Volume-to-capacity ratio
B. Pavement roughness index
C. Roadway surface type
D. Vehicle emissions level
Answer: A) Volume-to-capacity ratio
Rationale: The volume-to-capacity ratio indicates the degree of congestion, showing
how much traffic is flowing relative to the available capacity.
9. What is the primary purpose of traffic signal design at intersections?
A. To reduce vehicle emissions
B. To minimize travel time for vehicles
C. To improve safety and regulate traffic flow
D. To reduce fuel consumption
Answer: C) To improve safety and regulate traffic flow
Rationale: Traffic signals are used to control traffic movement at intersections to ensure
safe and orderly flow of vehicles and pedestrians.
10. The required stopping sight distance is determined by the vehicle’s:
A. Speed and reaction time
B. Speed and stopping time
C. Braking distance and reaction time
D. Total travel time
Answer: C) Braking distance and reaction time
Rationale: Stopping sight distance depends on the reaction time of the driver and the
vehicle’s braking distance at a given speed.
11. Which of the following is not a type of intersection?
A. T-intersection
B. Y-intersection
C. Roundabout
D. Median strip
Answer: D) Median strip
A. To minimize the cost of transportation
B. To ensure safety for all users
C. To balance traffic demand with available infrastructure
D. To improve air quality
Answer: C) To balance traffic demand with available infrastructure
Rationale: Transportation planning seeks to align traffic demand with infrastructure
capacity, ensuring efficient movement and reducing congestion.
