Road safety is a pressing problem in all countries of the world, road accidents, and the main cause of serious injury and loss of human life, constituting a challenge in the field both from a social and economic point of view.
The relationship between design geometry and crash rate is complex and not fully understand. Little information is available in the international literature on the relationships between design geometries and the number of road accidents, although it has been clearly demonstrated that very restrictive geometries, such as very short sight distances or tight (small radius) roadway curves, that are in significantly higher accident rates and certain combinations of factors causing unusually serious accidents.
Road safety depends on many factors, one of the most important sight distances.
The study aims to highlight the factors that contribute to the determination of sight distances, i.e. to increase road safety, given that there are no such studies in Romania. The study is carried out with the help of a specialized calculation software, Civil Site Design, software developed in Australia that allows road designers to work faster and smarter. The Civil Site Design application is developed by Civil Survey Solutions Australia, works on top of BricsCAD, AutoCAD, AutoCAD Civil 3D platforms and offers advanced functionalities for road design at Romanian standards.
