Theoretical differences between Overtaking Sight Distance and Sight Distance for Safe Overtaking
Abstract
The current legislation mentions the terms Overtaking Sight Distance and Sight Distance for Safe Overtaking, which are contained in the Rulebook on the conditions that road facilities and other elements of public roads must meet from the aspect of road safety and the Rulebook on Traffic Signage. The paper presents the theoretical procedure for Overtaking Sight Distance from a civil engineering perspective and the theoretical procedure for Sight Distance for Safe Overtaking from a traffic engineering perspective. After that, the theoretical differences between these two Sight Distances are presented based on the applicable Rulebooks. The place and role of the considered types of Sight Distances in road engineering are stated, as well as the impact of these differences in Sight Distances on Road Safety. This paper aims to inform the wider scientific and professional public about the differences between Overtaking Sight Distance, which civil engineers apply in their field of work, and Sight Distance for Safe Overtaking, which is applied by traffic engineers in their engineering work.
