42.3. Pedestrian Crossing Requirements

Try these first

1. 1.

   What is the minimum pedestrian green time formula?

   Hint

   Use the formula provided in class.

2. 2.

   What is the significance of startup lost time?

   Hint

   Consider why we can't start moving immediately at a green signal.

3. 3.

   What does 'G_p' stand for in the pedestrian crossing formula?

   • Startup lost time
   • Pedestrian green time
   • Crossing distance

   Hint

   Recall the formula discussed.

4. 4.

   True or False: Start-up lost time only applies to vehicles.

   • True
   • False

   Hint

   Think about what happens at signal changes.

5. 5.

   Design a conceptual plan for a busy urban intersection, detailing the pedestrian signal phases needed for various traffic levels. Explain how the startup time and pedestrian walking speed influenced your signal timing.

   Hint

   Use the suggested formulas and consider local pedestrian behaviors.

6. 6.

   Analyze an existing intersection in your community. What features facilitate pedestrian safety? Based on your analysis, recommend improvements and justify your choices.

   Hint

   Reflect on observations from the intersection.
