What is the primary objective of intersection design?
To maximize traffic flow speed
To ensure safe and efficient movement of vehicles and pedestrians
To increase road congestion
To reduce road capacity
Which of the following is NOT a factor affecting intersection design?
Traffic volume
Land use surrounding the intersection
The cost of nearby buildings
Vehicle types and maneuverability
What distinguishes an at-grade intersection from a grade-separated intersection?
At-grade intersections use bridges or tunnels
At-grade intersections have roadways crossing at the same level
Grade-separated intersections are always controlled by traffic signals
Grade-separated intersections have no impact on traffic congestion
Which of the following is NOT a type of at-grade intersection?
T-intersection
Roundabout
Cloverleaf interchange
Four-legged intersection
What is the primary purpose of ensuring adequate sight distance at intersections?
To allow vehicles to travel at maximum speed
To minimize the need for traffic signals
To provide sufficient reaction time for drivers to avoid collisions
To make intersections more visually appealing
Which factor does NOT influence the required sight triangle at an intersection?
Approach speed
Intersection control type
Vehicle color
Traffic volume
Which of the following is a characteristic of an all-way stop-controlled intersection?
Only major roads require stopping
Vehicles on all approaches must stop and yield to other traffic
No vehicle is required to stop unless pedestrians are present
All intersections are controlled by traffic signals
What is the main difference between stop-controlled and yield-controlled intersections?
Yield-controlled intersections require vehicles to stop completely
Stop-controlled intersections allow free-flowing traffic
Yield-controlled intersections allow vehicles to proceed without stopping if no conflicting traffic is present
Stop-controlled intersections have no sight distance requirements
Which of the following is NOT an advantage of roundabouts?
Reduced vehicular conflict points
Increased vehicle speed
Improved traffic safety
Continuous traffic flow
What is a major drawback of signalized intersections?
They increase intersection efficiency
They can cause delays during off-peak hours
They eliminate pedestrian crossings
They do not require maintenance
What is the ideal intersection angle for maximum safety and efficiency?
30 degrees
45 degrees
60 degrees
90 degrees
Why do skewed intersections present a challenge in intersection design?
They require additional pavement marking
They reduce sight distance and increase crossing distances
They encourage higher-speed turning movements
They eliminate pedestrian crossings
What is a common way to reduce conflict points at intersections?
Adding multiple uncontrolled access points
Implementing roundabouts or median barriers
Increasing the number of traffic signals
Reducing speed limits only
When designing a left-turn lane at an intersection, what must be considered?
Sight distance for turning vehicles
Adequate lane storage capacity
Potential conflicts with opposing traffic
All of the above
At a two-lane roundabout, which vehicle movement has priority?
Entering vehicles
Vehicles already in the roundabout
Pedestrians only
Exiting vehicles
