“…Lei [16] put forward that the semi-rigid guardrail could be studied as a coupling system together with the vehicle. Ibitoye et al [17] described a three-dimensional computer simulation of the kinematics impact of motorcycle and dummy rider with W-beam guardrail inclined at angles of 45°and 90°toward the initial direction of traveling. Zhang and Hu [18] discussed the importance of the soil behavior during a car-guardrail impact event and raised an effective method to investigate the soil behavior during impact.…”

“…In the 1990s, the International Organization for Standardization (ISO) developed the ISO13232 standard (ISO 2005), which was released in 1996 (Van Driessche 1994) and updated in 2005. The methodology defined in ISO13232 was promptly adopted by the research community (Aikyo et al 2015; Barbani et al 2014;Deguchi 2003Deguchi , 2005Ibitoye et al 2006;Van Auken et al 2005;Withnall et al 2003;Yamazaki et al 2001).…”

Objective: The ISO13232 standard provides guidelines and methodologies for research on the effectiveness of protective devices fitted to motorcycles. The accident database used to develop the standard was composed of 2 data sets from Hannover and Los Angeles, dating from 1996. This study aims to apply the methodology outlined in the standard to a more recent European accident database to determine whether the set of the 7 most relevant impact configurations identified in the ISO13232 are representative of the European context. Methods: The ISO13232 database was rebuilt from the data tables attached to the standard and processed according to the procedure described in ISO13232-Part 2, to ensure reproducibility of the results. The comparison data set was extracted from the Motorcycle Accidents In-Depth Study (MAIDS) database. Data were then coded, processed, and analyzed using the ISO13232 methodology. To eliminate any subjectivity in the selection process of the configurations, a new ranking criterion (configuration risk index, CRI) was implemented. The CRI combined the evaluation of an accident configuration's frequency of occurrence and its harmfulness. Results: Comparison of the frequency ranking of the impact configurations from the 2 databases revealed some notable differences. Five of the 10 most important configurations were common to both databases, although ranking order differed. CRI-based selection led to differences in ranking orders. The CRI allowed better identification of the most important configurations and it was employed to define the proposed new set of configurations. Conclusion: A new set of 7 accident configurations was defined by applying the ISO13232 procedure to the MAIDS data and ranking the results with a newly proposed method. The final set had only one configuration in common with those defined in the ISO13232, testifying to the importance of defining an updated and more representative set of configurations for the European context.

Abstract. Statistical data on traffi c accidents in 2008 inLithuania is presented. Referring to statistical data, 'grounding on an obstacle' makes one-tenth of all registered traffi c accidents -9.4% (an obstacle may be a road guardrail, a lamp post, a tree, a bar, a gate, etc.). Road guardrails of various types are installed on the shoulders and dividing strips of urban and suburban roads. Th ey are as follows: reinforced concrete guardrails, cable guardrails and metal guardrails. Metal guardrails, consisting of Σ-shape metal posts and a protective W-shape horizontal beam, are most popular. Th e authors of the present paper examine the deformation processes of the elements of the above mentioned guardrail. A mathematical model of metal road guardrail was developed. Metal road guardrail was modelled using onedimensional fi rst-order fi nite elements, taking into account only elastic deformations, as well as the eff ect of soil on the buried post section of the guardrail. Based on the developed mathematical model of metal road guardrail, the defl ections of its elements caused by the impact of a vehicle moving at varying speed were determined. Th e obtained values of defl ections of guardrail elements (a protective W-shape horizontal beam and a Σ-shape post) presented in paper do not exceed the admissible values (of beam defl ections).
