This paper contains the application of a heuristic method allowing the assessment of the rockfall risk along a Provincial road in Basilicata (Southern Italy) leading to an important lucanian geosite of growing touristic interest. The rockfall risk evaluation has been performed using an already published method based on the application of an exponential scoring function to several parameters concerning the geological characteristics of the slope and road and traffic data. A specific intensity matrix allowing a better assessment of the parameters linked to the rockfalls is hereafter described. The study case concerns the analysis of a rockfall phenomenon located along a road artery climbing up an important geosite that is to say the Lucanian Dolomites (Southern Italy) and connecting two villages of significant touristic importance: Castelmezzano and Pietrapertosa. The application of the RHRS 2.0 method allowed to obtain a medium risk level.
