“…There are approaches aimed to overcome these limitations. The work by Lubaś et al [2016] proposes a non-homogeneous asynchronous CA for modeling crowds where the transition rules are cell-dependent. On the other hand, the CA paradigm has become a popular test platform for studying pedestrian dynamics because of its computational simplicity.…”

Modeling pedestrian dynamics and their implementation in a computer are challenging and important issues in the knowledge areas of transportation and computer simulation. The aim of this paper is to provide a bibliographic outlook so that the reader could have a quick access to the most relevant works related with this problem. We have used three main axes to organise the paper contents: pedestrian models, validation techniques and multiscale approaches. The backbone of the paper is the classification of existing pedestrian models; we have organised the works in the literature under five categories, according to the techniques used for implementing the operational level in each pedestrian model. Then, the main existing validation methods, oriented to evaluate the behavioural quality of the simulation systems, are reviewed. Furthermore, we review the key issues that arise when facing multiscale pedestrian modeling, where we firstly focus on the behavioural scale (combinations of micro and macro pedestrian models) and secondly, on the scale size (from individuals to crowds). The paper begins introducing the main characteristics of walking dynamics and its analysis tools and concludes with a discussion about the contributions that different knowledge fields can do in a near future to this exciting area.

Although we have excellent tools to investigate the flow of evacuees in the building, these tools are rarely used in the development of optimal evacuation paths in the building, with a notable exception of large sports arenas [60]. The last part of the requirement -"(…) or be rescued by other means" indicates a possibility of providing a fire-safe area within the building, but requirements for such are not provided in the law.…”

Abstract. This paper presents modern application of fire safety engineering (FSE) in the shaping of civil engineering development. Presented scientific achievements of FSE become tools used in typical modern engineering workflow. Experience gained through successful implementations of these solutions is then further crafted into prescriptive laws that shape future fire safety. This diffusion of knowledge is limited by law requirements themselves, technical limitations, and yet unresolved challenges that are still being worked on by the researchers in this field. This paper aims to present the achievements of the FSE discipline that may and should be used by civil engineers and other participants of the building process. Explanations given for the choices of fire safety engineers allow a better understanding of their gravity by representatives of other engineering branches. That way it is possible to build empathy between different engineering disciplines, which may significantly improve both the building design process and safety of the buildings itself. The chosen framework of this paper is Appendix A to EU Construction Products Regulation defining basic goals for a fire safe building, with a possible application of FSE given for each of these goals. The current framework of performance-based FSE is presented in relation to the Polish legal system, with recommendations on how to improve both FSE and civil engineering in the future.Key words: fire safety engineering, fire protection engineering, fire protection, performance-based design, prescriptive codes. stakeholders who are not FSEs, may unwillingly influence the fire safety. This bidirectional connection requires a systematic, holistic approach to fire safety of a building, which is the essence of the philosophy of modern FSE. A sample of such approach, in the form of a framework for a good cooperation between fire experts and structural engineers, was presented by Abramowicz and Kowalski in [4]. Despite strict regulations and advanced design methodologies, supertall buildings or large road tunnels that can be considered the pinnacle of modern engineering are still the scene of catastrophic fire incidents. To reach the level of safety in which fires would cause no fatalities and limited damage, urgent problems beyond the quality of the design also have to be resolved, e.g. the slow diffusion of knowledge, the stress on reduction of fire protection cost, and abuse of overcomplicated methodologies, beyond their scope of application.
