13.2. Types of Sight Distance

Try these first

1. 1.

   What does SSD stand for?

   Hint

   Think about a safe stopping scenario.

2. 2.

   Name one factor that affects SSD.

   Hint

   Consider what changes how quickly a driver can stop.

3. 3.

   What does SSD stand for?

   • Stopping Sight Distance
   • Sight Stopping Distance
   • Driving Speed Distance

   Hint

   Consider the context of stopping distances.

4. 4.

   True or False: OSD only considers the speed of the overtaking vehicle.

   • True
   • False

   Hint

   Think about the dynamics during an overtaking maneuver.

5. 5.

   A vehicle travels at 90 km/h. Calculate the SSD if the reaction time is 2 seconds and the coefficient of friction is 0.3 on a level road. Also, how would a steep hill affect this distance?

   Hint

   Don't forget to convert speed and consider how gradient affects stopping.

6. 6.

   Two cars are heading towards each other at 70 km/h and 50 km/h respectively. Calculate the minimum sight distance required to avoid a head-on collision.

   Hint

   Break down the calculations for each vehicle and sum them up!
