“…Some examples of cases not included in EN 1317 standards (e.g. barrier on road's arc or an obstacle behind the barrier) were studied in the works [5][6][7]. Other examples of using numerical simulation to perform crash tests considering barriers were presented in the papers [8][9][10].…”

Cable barriers are commonly used on Polish roads, including motorways and local roads. Their main elements are pre-stressed wire ropes, which are usually anchored at two ends in concrete blocks buried in the soil. In this work numerical studies concerning the influence of selected construction features and parameters of the vehicle motion on the performance of cable barriers were performed. Numerical simulations are a useful tool to conduct such analyses that is now being used more and more. The calculations were carried out by using finite element code of LS-DYNA.

“…The EN 1317 standards consider a limited number of crash test configurations, in addition, they only apply to straight section of the safety barrier, with impact point in its middle section. Whereas in reality there are many different cases, these mentioned standards do not include, like barriers installed on horizontal and vertical road curves (concave and convex) [4], variation of vehicle type, velocity and angle of impact, weather or soil conditions (they may not be the same as in the real test) [5], the influence of distance between the barrier and the road or curb [6] or different barrier lengths, in a particular case the barrier may be short, thus not as secure as their full-length parent. In addition, simulations allow to analyse the influence of various obstacles such as truss supporting structure located directly behind the barrier.…”

Road safety barriers are used to increase safety in potentially dangerous places on the roads. They are designed and installed on the roads to prevent any vehicle from getting outside the travelled way or from entering the opposite lane of the road. Barriers, which are used on European roads, have to undergo full scale crash tests according to the EN 1317 standards. Nowadays as a supplement to real crash tests, numerical simulations are commonly used. The work concerns the influence of position of the post or its absence on the crashworthiness of the cable barrier based on numerical study results.

The reliable speed of a vehicle, assigned to a given road arc, is not usually taken into account in simulation of crash tests on road safety barriers located on horizontal concave arcs with small radii (20−200 m). In this work, the numerical modelling and simulations of TB11, TB32 crash tests for selected road safety barriers on a horizontal concave arc with a small radius of 150 m, at a reliable and increased speed of a vehicle, were conducted. The authors developed the methodology of numerical modelling and simulation and published in the period 2015−2018. In this study, crash tests include two N2 class steel road barriers with the B-type guide rail, i.e. SP-05/1 (with 1.00 m post spacing) and SP-05/2 (with 2.00 m post spacing). Suzuki Swift and Dodge Neon vehicle models were taken from the National Crash Analysis Center (USA) library and modified, respectively. It was proved that road traffic safety on horizontal concave arcs with small radii is assured if the reliable velocity is not exceeded by drivers. Compacting the post spacing or the uses of a composite-foam protective overlay added to guide rails are not recommended.
