B Expand highways
C Increase vehicle speed
D Decrease road maintenance
Using public transportation reduces the number of private vehicles on the road, which lowers fuel consumption and reduces emissions. It helps mitigate the environmental impact of transportation by providing an efficient, eco–friendly alternative to driving.
What is the primary goal of traffic management?
A Increase car ownership
B Prevent accidents
C Reduce fuel consumption
D Improve road aesthetics
Traffic management focuses on controlling traffic flow to minimize accidents and improve road safety. Techniques like signal optimization, real–time monitoring, and congestion management help reduce collisions and improve the overall safety of road users.
What is a common method for traffic flow optimization?
A Road surface texture
B Road widening
C Signal timing adjustment
D Increasing lanes
Optimizing signal timings ensures smooth traffic flow at intersections. By adjusting the length of red, yellow, and green lights based on real–time traffic data, congestion can be reduced, and traffic delays minimized.
How does ITS improve road safety?
A Provides real–time traffic updates
B Increases traffic accidents
C Controls vehicle speed
D Reduces road signage
ITS enhances road safety by providing drivers with real–time information about traffic conditions, accidents, and hazards. This allows drivers to make informed decisions, avoid congested areas, and reduce the likelihood of collisions.
What is a key benefit of sustainable transportation systems?
A Increased car ownership
B Reduced environmental pollution
C Decreased fuel consumption
D Increased road capacity
Sustainable transportation systems, such as electric vehicles and public transit, reduce the environmental impact of travel by lowering carbon emissions. These systems contribute to cleaner air, less traffic congestion, and a more sustainable urban environment.
What is the goal of transportation demand management?
A Promote private car usage
B Widen roadways
C Increase traffic accidents
D Reduce travel demand
Transportation demand management (TDM) focuses on reducing the need for road use by encouraging alternatives like public transportation, carpooling, and biking. It helps alleviate congestion, lower emissions, and promote sustainable transport practices.
What does urban transport planning primarily aim to improve?
A Public transport usage
B Fuel consumption
C Road speed
D Road surface quality

B More vehicle lanes
C Increased traffic volume
D Reduced carbon footprint
Sustainable transport systems prioritize eco–friendly travel methods, such as electric buses, bicycles, and walking. These reduce the carbon footprint of transportation by minimizing greenhouse gas emissions and promoting cleaner, more energy–efficient travel options.
What does the term “traffic volume studies” refer to?
A Road width determination
B Weather condition analysis
C Traffic speed measurement
D Analysis of vehicle numbers
Traffic volume studies measure the number of vehicles passing a specific point over a certain period. This data is essential for planning road capacity, traffic signals, and infrastructure to accommodate growing traffic demands.
What is a major advantage of using traffic simulation in road design?
A Increase road lanes
B Improve vehicle speed
C Test real–world traffic conditions
D Predict fuel consumption
Traffic simulation helps engineers and planners evaluate how traffic behaves under different conditions. By modeling real–world scenarios, planners can assess the effectiveness of proposed road designs, optimize traffic flow, and make adjustments before construction begins.
