Abstract

The issue of sight distance evaluation on suburban single-lane roundabouts is analysed. An overview of regulations, standards and guidelines applied in Austria, France, Croatia, USA, Serbia, and Switzerland, which describe procedures for determining the necessary sight distance, is given. Influential parameters for defining clear vision areas for intersections, defined in the aforementioned documents, are presented in detail. An emphasis is placed on the diversity of sight distance evaluation approaches, and test results obtained on a theoretical example of a suburban roundabout are commented on.
