What is an important consideration in the design of drainage systems for highways?
A Vehicle speed
B Road alignment
C Pedestrian traffic
D Drainage capacity
The capacity of a drainage system is crucial to ensure that water is efficiently removed from the road surface. Proper drainage prevents flooding, reduces road erosion, and ensures safety by maintaining road conditions during adverse weather.
What is the purpose of road user behavior studies?
A Understand driver actions
B Improve fuel economy
C Design better roads
D Reduce traffic congestion
Road user behavior studies analyze how drivers respond to various traffic conditions, signs, and road features. Understanding these behaviors helps in designing road systems that are intuitive and reduce the likelihood of accidents.
What is the environmental benefit of rail transport over road transport?
A Increased emissions
B Lower fuel consumption
C Higher congestion
D More road wear
Rail transport is more energy–efficient compared to road transport, as trains can carry more passengers and cargo with less fuel per unit. This leads to reduced emissions and lower overall fuel consumption, making rail a more environmentally friendly option.
What is a common challenge in maintaining highways?
A Road aesthetics
B Traffic management
C Pavement degradation
D Pedestrian facilities
Pavement degradation due to heavy traffic, weather conditions, and natural wear is a common challenge in highway maintenance. Regular inspections and repairs are essential to maintain road quality and prevent further deterioration, ensuring safe driving conditions.
