  Key to understanding the needs and building road infrastructure management tools to prevent and mitigate run-off-road accidents is to identify hazards and their sources which are a result of wrong design, construction, and installation of road restraint systems. Building such tools requires advanced studies with field tests, simulations and models to demonstrate the effects of selected parameters on road user safety. The research...

  Uziemienia słupów linii energetycznych powinny być sprawdzane okresowo. Pomiary rezystancji takich uziemień przy pomocy metody niskoczęstotliwościowej wymaga wyłaczania linii i odkręcania przewodów odprowadzających od konstrukcji słupa. Metoda udarowa jest znacznie łatwiejsza w tej aplikacji i nie wymaga wyłaczania linii na czas pomiarów. W pracy oszacowano wpływ uziemień sąsiednich słupów na dokładność pomiarów metodą udarową.
