2.3. Gradient and Cross-Fall

Try these first

1. 1.

   What should be the maximum longitudinal gradient for pedestrian paths?

   Hint

   Think about how steep paths should preferably be.

2. 2.

   What is the maximum allowable cross-fall for sidewalks?

   Hint

   Consider the need for stability while walking.

3. 3.

   What is the maximum longitudinal gradient allowed for pedestrian paths?

   • 1:10
   • 1:20
   • 1:30

   Hint

   Look for the slope that is easier for navigation.

4. 4.

   True or False: Cross-fall should be greater than 1:50 to prevent water pooling.

   • True
   • False

   Hint

   Think about equitable safety.

5. 5.

   Design a hypothetical pedestrian pathway in an urban area with a gradient of 1:30 and a cross-fall of 1:40. Discuss the potential risks for users with mobility difficulties.

   Hint

   Analyze user experiences in similar scenarios.

6. 6.

   Propose solutions for retrofitting existing pedestrian pathways that do not meet the recommended gradient and cross-fall specifications, discussing stakeholder involvement.

   Hint

   Consider accessibility laws and guidelines.
