Line of Sight

What is Line of Sight?

Definition of Line of Sight in Construction
The line of sight normally refers to access from a construction site and a completed project onto a roadway or other traveled pathway.

The line of sight is the distance a driver can visually see, when exiting the project. The Highway Department of the local municipality will determine the length of the required line of sight, depending upon the approaching speed of the traffic, as well as the gradient of the roadway. The line of sight is critical when designing intersections and new roadways. The use of signals, stop signs and other means of controlling the traffic flow, all consider the line of sight. Not only is the line of sight influenced by distance, it is severely limited by gradients within the roadway itself. If the roadway rises and drops, the line of sight is reduced due to this elevation change.
