13.5. Sight Distance at Intersections

Try these first

1. 1.

   What does SSD stand for?

   Hint

   Think about the distance needed to stop a vehicle safely.

2. 2.

   Why is sight distance important at intersections?

   Hint

   Consider the actions needed when encountering another vehicle.

3. 3.

   What is the purpose of sight distances at intersections?

   • To allow vehicles to speed up
   • To enable perception of hazards
   • To confuse drivers

   Hint

   Focus on what helps drivers avoid accidents.

4. 4.

   True or False: SSD is influenced by the speed of the vehicle.

   • True
   • False

   Hint

   Consider how speed impacts stopping distances.

5. 5.

   You are evaluating an intersection with a posted speed limit of 60 km/h. Considering environmental factors, propose the SSD required if road conditions are ideal.

   Hint

   Convert the speed into meters per second and find coefficients.

6. 6.

   Design an intersection layout that accommodates all road users. Include sight distances for vehicles and pedestrians.

   Hint

   Think about both vehicles and pedestrian crossing needs.
