The paper describes a method for choosing the optimal lighting plan related to the roundabout dimensions. The method has been set up taking into account various illumination requirements and recommended standards, lighting apparel features and roundabout geometric characteristics. Moreover, the comparison between the central island solution and the perimetric location is completed by the inclusion of an estimation of the specific costs and related savings. All experimental findings are summarized into diagrams and tables allowing the designer to make the most proper lighting plan for a given design value of the inscribed diameter D, or vice versa. Our results are extended to values of D ranging from 20 to 38 m and therefore the whole range of compact roundabouts is covered. These experimental results seem to confirm that the central solution is the best lighting practice for any compact roundabout.

Abstract
The paper describes a method for choosing the optimal lighting plan related to the roundabout dimensions. The method has been set up taking into account various illumination requirements and recommended standards, lighting apparel features and roundabout geometric characteristics. Moreover, the comparison between the central island solution and the perimetric location is completed by the inclusion of an estimation of the specific costs and related savings. All experimental findings are summarized into diagrams and tables allowing the designer to make the most proper lighting plan for a given design value of the inscribed diameter D, or vice versa. Our results are extended to values of D ranging from 20 to 38 m and therefore the whole range of compact roundabouts is covered. These experimental results seem to confirm that the central solution is the best lighting practice for any compact roundabout.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
