WebThe Stopping Sight Distance (SSD) = Lag Distance + Braking Distance. -> SSD = vt + (1/ (2fg))v2. Here, v is the speed in m/s 2, t is the reaction time taken, f is coefficient of friction, g is the acceleration due to gravity. The Table-1 Below shows the coefficient of friction for different design speeds. http://dnoonan.ie/surveying/site-access#:~:text=Speed%20surveys%20can%20be%20undertaken%20to%20record%20the,is%20not%20always%20equal%20to%20the%20speed%20limit.
