Available stopping sight distance profile determinates ASSD on each driver position.
The ASSD on the left turn curve is greater than the right turn curve because the driver on the left turn is located on the top of the superelevation plain and has more clearance.
1], %), length of horizontal curve (L, m), and ratio between the crest curve parameter and radius (Kv/r, -) were studied by comparing minimum ASSD on the simulated scenarios.
6 represents ASSD profile of a left-handed curve with horizontal radius equal to 250 m depending on the offset.
Secondly, the effect of the ratio between crest curve parameter and radius (Kv/R) on ASSD varied depending on algebraic difference of grades.
Variability on ASSD was higher on curves with more deflection angle; and the influence of the difference on grades was higher on curves with shorter radii.
