Wpływ czasu i warunków eksploatacyjnych na trwałość i funkcjonalność elementów bezpieczeństwa ruchu drogowego

Celem projektu jest opracowanie wytycznych i instrukcji dotyczących projektowania i utrzymania urządzeń brd. W ramach projektu określony zostanie wpływ wybranych czynników drogowych, eksploatacyjnych i technicznych na trwałość i funkcjonalność wybranych rodzajów urządzeń organizacji ruchu i plastikowych urządzeń brd, a także wybranych rodzajów stalowych i betonowych urządzeń brd. Zostaną wykonane badania wpływu zmian trwałości i funkcjonalności badanych urządzeń brd i organizacji ruchu na ich skuteczność, efektywność ekonomiczną i wykonalność techniczną. Dodatkowo zostaną określone zasady ubezpieczenia i realizacji odszkodowań za szkody spowodowane zderzeniami pojazdów z urządzeniami brd.

- Archives of Civil and Mechanical Engineering - Year 2020
The paper addresses numerical simulations of a concrete vehicle restraint system. The model is described in detail. The advanced material law of the continuous surface cap model was used to analyze the damage locations in concrete barrier segments. The results were validated against the TB41 full-scale crash test. The test was conducted in compliance with European standard EN 1317, and the validation was performed in accordance...

Experimental and numerical analysis of the modified TB32 crash tests of the cable barrier system
Publication
- ENGINEERING FAILURE ANALYSIS - Year 2019
Road restraint systems, including safety barriers, are one of the means used to improve road safety. Currently, they can be allowed to general use after passing the specific crash tests. However, it is always important and desirable to evaluate their performance under various realistic conditions, which can happen on the roads. In this study, the behaviour of the cable barrier system in impact conditions different than assumed...

- MATEC Web of Conferences - Year 2018
This paper discuss the influence of selected factors on the performance of a concrete road barrier H2/W5/B. Modelling techniques of a concrete road safety system were briefly discussed. Comparison to the full scale crash test results has been shown. The concrete road safety barrier has been investigated for evaluation of the overall damage after collision under various initial conditions. The failure assessment criterion has been...
