‘Sight Distance’ is considered in the design of
-
- Road intersection
- Fenestration
- Open kitchen
- Auditorium
Correct Option: A
Sight distance available from a point is the actual distance along the road surface, over which a driver from a specified height above the carriage way has visibility of stationary or moving object s. Three sight distance situations are considered for design :
⋅ Stopping sight distance (SSD) or the absolute minimum sight distance
⋅ Intermediate sight distance (ISD) is defined as twice SSD
⋅ Overtaking sight distance (OSD) for safe overtaking operation
⋅ Head light sight distance is the distance visible to a driver during night driving under the illumination of head lights
⋅ Safe sight distance to enter into an intersection
