What is it about?
The paper presents a practical procedure using a completely new index to determine whether a sight-hidden dip (SHD), a common shortcoming in the alignment of highways, may be critical for traffic safety. 23 road segments were evaluated under this approach.

Why is it important?
Sight-hidden dips could be a hazard for drivers since head-on crashes may occur during passing manoeuvers.
Perspectives
Shortcomings in perspective can create potential issues in highway operation as they mislead drivers. This study provides a method to address decision making.
