2. 2.

   What is amber time?

   Hint

   Recall the color of the traffic light before red.

3. 3.

   What is green splitting?

   • Dividing green time based on traffic volume
   • Allocating all green time to heavy traffic
   • Ignoring pedestrian signals

   Hint

   Think about fairness in traffic allocation.

4. 4.

   True or False: Effective green time includes amber time.

   • True

5. 5.

   Design a traffic signal phasing plan for a new intersection with a mixed traffic flow of vehicles and pedestrians, considering the zoning laws in your area.

   Hint

   You can use population data or traffic surveys to estimate volumes.

6. 6.

   Analyze how delays at a heavily trafficked intersection could be mitigated through signal timing changes and pedestrian phase integration.

   Hint

   Consider peak traffic hours and how they differ from off-peak.
