“…The most relevant parameters were those that affected the search for local maxima, namely, those related to minimum crown size (mc) and minimum tree height (mh). The following pairs of parameters were adopted (mc [m], mh [m]): [ (3,10), (4,20), (5,40)].…”

Modern technologies, such as airborne laser scanning (ALS) and advanced data analysis algorithms, allow for the efficient and safe use of resources to protect infrastructure from potential threats. This publication presents a study to identify trees that may fall on highways. The study used free measurement data from airborne laser scanning and wind speed and direction data from the Institute of Meteorology and Water Management in Poland. Two methods were used to determine the crown tops of trees: PyCrown and OPALS. The effect of wind direction on potential hazards was then analyzed. The OPALS method showed the best performance in terms of detecting trees, with an accuracy of 74%. The analysis showed that the most common winds clustered between 260° and 290°. Potential threats, i.e., trees that could fall on the road, were selected. As a result of the analysis, OPALS detected between 140 and 577 trees, depending on the chosen strategy. The presented research shows that combining ALS technology with advanced algorithms and wind data can be an effective tool for identifying potential hazards associated with falling trees on highways.

“…The second important parameter of the analysis was the direction of the wind gust, defining the origin of the direction from which the wind blows. These are given descriptively according to the eight-directional wind rose as follows [39,40]:…”
