Question 1.
Define what a phase is in traffic signal design.
Show hintHide hint
Think about what happens during a traffic signal change.
Question 2.
What is the significance of grouping non-conflicting flows?
Show hintHide hint
Consider the relationship between efficiency and safety.
3Question 3.
What does a phase in a traffic signal refer to?
- Only the green light
- The complete cycle of lights
- The green interval and change intervals
Show hintHide hint
Consider what happens when lights change.
4Question 4.
Two-phase signals are most effective when:
- True
- False
Show hintHide hint
Think about the flow of cars.
Question 5.
Design a two-phase signal for an intersection where there are two through lanes, one left-turn lane and one right-turn lane. Discuss how you would group the flows and any potential conflicts.
Show hintHide hint
Consider how traffic flows intersect and potential accidents.
Question 6.
Evaluate a scenario where high left-turn traffic is present at a two-phase signal. What adjustments would you recommend?
Show hintHide hint
Think about how turning movements affect all vehicles at the intersection.
