“…With the development of modern technology, both active vehicle safety, such as various assistance systems and technical devices aimed at preventing accidents, and passive safety, aimed at mitigating the consequences of accidents, are improving. However, the number of road accidents and accidents with serious consequences is still high and it is necessary to focus on developing [1][2][3] a safe transport system with socially acceptable levels of safety. In the event of an accident, the aim of passive safety is to mitigate the consequences as much as possible.…”

The topic of the article are vehicle restraint systems. Specifically, the paper focuses on the safety analysis of the way of implementation of crash cushions. Within the safety analysis carried out on the territory of the Ústí Region of the Czech Republic, the most frequently occurring deficiencies in crash cushions and their possible impacts on road safety were identified. The output is the creation of catalogue sheets of crash cushions, which contain the most frequently installed crash cushions on the road network and a summary of methodological requirements for their adequate implementation. The work is intended to serve as an effective tool and a quality source of information for road managers and road safety auditors during their subsequent inspection.

“…One of the problems related to the increase in mobilization, especially in developing countries, is ensuring roadside traffic safety. To prevent or reduce the problems caused by traffic accidents, highway and traffic engineers make intense efforts and offer different solutions (Wright 1983;Roque et al 2015;Ramiani and Shirazian 2020;Yumrutaş and Othman Ali 2022).…”

“…The results were successful for possible future novel barrier types. Yumrutaş and Ali (2022) developed renewable hybrid barriers using waste materials (slag and tyre). In this regard, they conducted pendulum crash tests to assess the performance considering the EN 1317 (2010) road restraint systems standard.…”

Researchers have recently focused on new and original roadside barriers that prioritize aesthetic, and environmental concerns by employing natural materials. In this study, the safety performance (Acceleration Severity Index (ASI), Theorical Head Impact Velocity (THIV)), structural performance (Working Width (W), Exit Angle (α)), and failure analysis (visual deformation) of a newly developed Renewable Hybrid Barrier (RHB) system at different timber thicknesses were tried to be determined by pendulum crash test and Finite Element (FE) models. The FE models were calibrated and validated based on pendulum crash test results, and then the most suitable timber thickness in terms of safety and structural performance was determined via FE analyses. The results revealed that as the timber thickness decreased, the safety parameters, such as ASI and THIV, decreased, thus the barrier safety increased. However, it was observed that the deflection and deformations in the barrier increased as the timber thickness decreased. In this sense, the safest and the most structurally durable barrier was determined through conducting virtual optimization tests. Studies on diversification of the usage areas of natural/renewable materials should be increased in the future.
