: According to road design guidelines, unsignalized intersections should have certain free sight fields to ensure that vehicles approaching from different directions see each other. However, in many cases these sight fields include some obstacles which cause safety concerns. The identification of these obstacles and the planning of appropriate interventions would improve safety. In this article, we present an analysis method suitable for visibility investigation based on a laser scanner survey. We review the methods developed in recent years to select the visible and hidden points of the point cloud. Based on the presented results, we developed a procedure that is consistent with the concept of sight distance used in the field of road design. The survey was taken from an observation point of the drivers on the minor road and the sightlines were projected onto a reference plane along the major road, considering the required sight distance. The projected results appeared as "shadows" from the visibility obstacles on the reference plane. The visibility difficulties detected can be used to decide the appropriate actions to improve the safety of the intersection.
