Road markings are used to guide drivers on the road by indicating lanes, directions, and stopping points. These markings ensure safe driving, helping drivers navigate intersections, curves, and pedestrian crossings.
What does highway capacity refer to?
A Road material
B Intersection design
C Traffic volume
D Road width
Highway capacity refers to the maximum number of vehicles that can pass a point on a highway during a given time period. It is essential for designing roads that can handle expected traffic volumes efficiently.
What is the goal of road safety measures?
A Speed regulation
B Accident prevention
C Increase road width
D Improve aesthetics
Road safety measures aim to reduce the likelihood of accidents. These measures include proper signage, traffic calming techniques, road design improvements, and regular safety audits to ensure roads are safer for all users.
What is the purpose of intersection design?
A Control traffic speed
B Increase road capacity
C Facilitate safe vehicle movements
D Improve lighting
Intersection design focuses on creating efficient and safe vehicle movements at junctions. Proper lane width, signalization, and clear markings help prevent accidents and improve the flow of traffic at intersections.
What is the main feature of freeway design?
A Multiple lanes
B Pedestrian access
C Low cost
D Narrow lanes
Freeway design incorporates multiple lanes to accommodate high speed, uninterrupted traffic. This design ensures a smooth flow of vehicles and helps avoid bottlenecks, making it ideal for long distance travel and reducing congestion.
What is the function of noise barriers in highways?
A Increase speed
B Prevent flooding
C Reduce accidents
D Block sound
Noise barriers are placed along highways to reduce the impact of traffic noise on nearby communities. By absorbing or reflecting sound, they help improve the living environment for those who live near busy roads.
What is the primary function of roadside expressways?
A Reduce traffic
B Facilitate high speed travel
C Provide pedestrian access
D Improve aesthetics
Roadside expressways are designed for high speed traffic. They provide a route for vehicles to travel long distances quickly, with limited access points and no intersections, allowing for efficient travel and reducing travel times.
What does transport policy in highway engineering aim to achieve?
A Improve aesthetics
B Increase vehicle speed
C Sustainable transportation systems
D Prevent accidents
Transport policy aims to create an efficient, sustainable transportation network that balances economic growth with environmental concerns. It includes strategies for reducing congestion, promoting public transport, and using eco friendly road technologies.
What does public private partnership (PPP) in road construction achieve?
A Government control
B Increase toll fees
C Improve road design
D Faster project completion
Public private partnerships combine the efficiency of the private sector with public investment to accelerate the construction and maintenance of roads. PPPs help deliver infrastructure projects faster and more cost effectively.
What is the purpose of quality control in highway construction?
A Increase traffic flow
B Ensure material strength
C Speed up construction
D Enhance aesthetics
Quality control ensures that construction materials meet the required standards for strength and durability. This prevents failures such as cracks, deformations, and road surface issues, ensuring the road lasts longer and performs well under traffic.
What is the primary aim of road widening?
A Prevent accidents
B Improve road safety
C Accommodate more vehicles
D Add more lanes
Road widening is typically done to increase the road’s capacity to handle more vehicles. This can be achieved by adding lanes, widening shoulders, or improving intersections to reduce congestion and improve traffic flow.
What is one major focus of highway construction techniques?
A Efficiency and safety
B Cost reduction
C Aesthetic appeal
D Increase tolls
Highway construction techniques prioritize efficiency to reduce time and cost while ensuring safety during both construction and after completion. These techniques involve using durable materials and designs that ensure long term performance.
What is the role of road markings on highways?
A Control traffic speed
B Prevent accidents
C Indicate lane positions
D Improve visibility
Road markings play a critical role in maintaining lane discipline by visually indicating the boundaries of lanes, stopping points, pedestrian crossings, and directions. Proper markings ensure smoother traffic flow and reduce confusion.
What is a primary concern in the design of intersections?
A Pedestrian access
B Road aesthetics
C Material cost
D Traffic volume
Intersection design must consider traffic volume to ensure that the road can accommodate the number of vehicles using it. Proper design reduces congestion, improves traffic flow, and minimizes delays at junctions.
What is the goal of pavement rehabilitation?
A Restore surface integrity
B Add new lanes
C Increase road width
D Improve aesthetics
Pavement rehabilitation restores the functionality of roads by addressing surface damage such as cracks, potholes, and rutting. This process extends the life of the road and ensures it remains safe for traffic.
