What are the types of highway sight distance?
1 Answers
Highway sight distance types include stopping sight distance, overtaking sight distance, meeting sight distance, and passing sight distance. Introduction to stopping sight distance: The minimum distance required for a vehicle to come to a safe stop after the driver sees an obstacle ahead while driving. Introduction to meeting sight distance: On the same lane when two opposing vehicles meet, the minimum distance required from the moment they spot each other until both apply brakes to come to a safe stop simultaneously. Introduction to passing sight distance: On two-lane roads without clearly marked lane dividers, the minimum distance required for two opposing vehicles to safely pass each other after spotting each other and taking appropriate deceleration/avoidance measures.
