Abstract. Effective and safe transportation infrastructure presents one of the crucial conditions for functional society. Its ceaseless development and construction can be taken as a proof of its importance even despite the corresponding financial and time demands. The complexity and scale of the projects related to transportation infrastructure presents an ideal field for implementation of the BIM approaches. However, it is necessary to implement the BIM to the whole life cycle of the transport structure, especially not only to the pre-investment and investment phases but also to the operation and maintenance. For every road infrastructure, it is important to observe the performance of the road, behaviour of road users and evaluate the resulting safety risks, to be able to correspond with adequate and effective measures and to secure sufficient level of safety. The paper aims to present an implementation of the road safety aspects and statistics into the processes of BIM applications and strategies, which are prepared on the base of Government Resolution No 958, on the importance of the Building Information Modelling (BIM) in the Czech Republic. The accident statistics, safety audits and inspections presents a valuable source of information that should be adequately implemented with the BIM processes.

Abstract. Sustainability is one of the main scientific and public topics of today. This includes the sustainable transport and infrastructure. One of the ways how to achieve higher level of sustainability is through the implementation of BIM (Building Information Modelling) into the road design process. However, to create a safe road network, which is also necessary for achievable sustainability, it is essential to consider the Road Safety Audit (RSA) principles throughout the BIM applications. The paper discusses the possibilities of involving the RSA in the process road design in I-BIM (Infrastructures Building Information Modelling). Within the individual phases of the preparation of a transport project and the application of the safety audit tools in BIM applications, it is possible to achieve a significant increase in the level of safety. This approach is shown within the paper on the implementation and use of supplementary road safety devices, specifically the road restraint systems. Currently, the individual components are defined by their main parameters in specific libraries. However, their definition is only as a general object where many of the supplementary parameters or fundamental design characteristics, such as working width or minimal length, are not included. This may lead to potential design flaws or safety hazards which have to be subsequently corrected in further phases. The objective of the paper is to identify the current deficiencies, primarily the missing road safety perspective within the BIM process. The aim is to enable appropriate selection of safety equipment during the design or to provide sufficient information for the mandatory RSA.
