“…There is no general consensus within the literature whether people naturally use the left or right side of stairways, because the choice can depend on a number of factors (such as the staircase configuration and entry / exit points, presence of other people, and personal space available). 17,18 Similarly, walking speeds can vary depending on length of stairway 19 or level of physical exhaustion. 20 Preliminary observations were carried out to determine the types of behaviours that could be observed on this staircase, such that any differences in behaviours after fitting of the lights could be considered.…”

Features of lighting that can influence people’s behaviours have been identified in an earlier study, along with six scenarios where these could be applied to solve problems with movements through railway stations. The current paper describes the development and testing of novel lighting interventions for three of these scenarios, with two new products controlled by the Internet of Things technology integrated with operational railway systems. The first uses projected light to indicate preferred platform waiting locations. The second uses chasing light-emitting diode lighting along a staircase to encourage bi-directional movements. The field study has been carried out in real-world operational railway settings. An evaluation has been based on a theory-based approach to consider whether the lighting functions as intended and whether people react in anticipated ways. The study found that the lighting interventions have been successfully implemented, and there are indications of favourable responses from passengers, though these have been small effects. The approach to evaluation also assists with diagnosis of weaknesses in the initial concepts and determination of the situational factors that can compete with the behaviour influencing effect of the lighting. This enables refinement and further product development. Practical challenges in implementing trials in this type of operational setting have been identified.

“…Two aspects are usually considered in regards of the stairs; the stairs design and the occupants' behaviour on stairs [91]. In [102], the authors describe a model that considers the specifications of personal space to describe uni-and bi-directional pedestrian movement on stairs. In spite of this model being presented for non-emergency evacuations, the parameters outlined can be considered for emergency situations if other inputs are measured.…”

Crowd evacuation in emergencies may lead to fatalities if the evacuation plans were not tested and evaluated. Traditionally, evacuation drills have been, and still are, being used to assess evacuation plans. However, in recent years the simulation of evacuation plans during emergencies has emerged as a strong alternative that is cost effective and potentially more accurate. Agent-Based Simulation (ABS) is the preferred type of simulation for evacuation scenarios, due to its ability to model individual decisionmaking and social behaviour. In this paper we conduct meta-analysis of eighty-one peer-reviewed papers published between 2009 and 2019 that used ABS to model pedestrian evacuation. Our analysis assesses the current state-of-art and identifies opportunities for improvement. We identify seven dimensions over which the surveyed papers agree or differ. The dimensions include purpose of the simulation, type of emergency and environment considerations, type and scale of evacuated space, simulation software used, agents' characteristics and behaviour, support of evacuation policies, and analysis and validation. We conduct meta-analysis of the surveyed papers along the identified dimensions. One of the main findings of our analysis is the lack of a standardized validation methodology for ABS of emergency evacuation.

“…Liu et al demonstrate that the personal space (which is represented by a perimeter or some physical limits, between which a certain person feels in their comfort zone while standing or sitting in a place near another person) influences the comfort and safety feelings a person has during an evacuation, with a direct impact on reducing his/her velocity [28].…”

Establishing the Proper Seating Arrangement in Elevated Lecture Halls for a Faster Evacuation Process

et al. 2019

As time is crucial in the human evacuation process during an emergency situation, several aspects related to how the humans involved in such a process act have been studied over the time, underlying that the humans' behavior is rather unpredictable and depends on social background, emotions, the degree of familiarity with the environment, age, gender, and so on. On the other hand, it has been determined that the characteristics of the environment are important in such situations as they may facilitate a shorter evacuation time. It has been shown that exits characteristics, such as width or their number, have a positive direct impact on the evacuation time. In this context, this paper aims to analyze another environmental aspect, namely, the seat arrangement, and to determine how the seats should be placed in order to reduce the evacuation time for a given configuration of the doors. On this purpose, an elevated lecture hall with two exits has been chosen, as it represents one of the most populated places within the public buildings, characterized not only by a high population density but also by a limited capacity to escape. A case study has been conducted using 97 human subjects and an agent-based model has been created considering their individual characteristics. The model has been simulated on eight different seat arrangements for 15 different positions on the two exitdoors. As a result, the proper seating arrangement for each of the 15 exit-door positions has been presented along with the study's limitations.
