“…Currently, ease of wayfinding is evaluated using four approaches: real field testing [10], virtual field testing [11,12], CAD model analysis [13], and wayfinding simulation [14][15][16][17][18][19][20]. In real field tests [10], a certain number of human subjects are asked to perform experimental wayfinding tasks in a real environment.…”

“…However, this approach cannot evaluate ease of wayfinding in terms of signage visibility, legibility, and noticeability because three-dimensional (3D) interactions between individuals and signage are not considered. Recently, a variety of wayfinding simulations has been proposed [14][15][16][17][18][19][20]. Such simulation-based approaches have made it possible to evaluate the ease of wayfinding by simulating the wayfinding of the pedestrian model.…”

Abstract:As recommended by the international standards, ISO 21542, ease of wayfinding must be ensured by installing signage at all key decision points on walkways such as forks because signage greatly influences the way in which people unfamiliar with an environment navigate through it. Therefore, we aimed to develop a new system for evaluating the ease of wayfinding, which could detect spots that cause disorientation, i.e., "disorientation spots", based on simulated three-dimensional (3D) interactions between wayfinding behaviors and signage location, visibility, legibility, noticeability, and continuity. First, an environment model reflecting detailed 3D geometry and textures of the environment, i.e., "as-is environment model", is generated automatically using 3D laser-scanning and structure-from-motion (SfM). Then, a set of signage entities is created by the user. Thereafter, a 3D wayfinding simulation is performed in the as-is environment model using a digital human model (DHM), and disorientation spots are detected. The proposed system was tested in a virtual maze and a real two-story indoor environment. It was further validated through a comparison of the disorientation spots detected by the simulation with those of six young subjects. The comparison results revealed that the proposed system could detect disorientation spots, where the subjects lost their way, in the test environment.

“…With crowd behaviour model, building environment can be dynamically perceived by individual, and the individual behaviours in different scenarios can be simulated, the spatiotemporal location of the individuals can be calculated dynamically , the intelligent management and decision-making of crowd evacuation can be realized finally (Shi, 2009). Based on path finding model, with model parameters (e.g., crowd spatiotemporal distribution, position and width of exits) and the modelling goals (e.g., ease congestion, reduce the total evacuation time, reduce the fire hazards to crowd), crowd evacuation paths can be calculated intelligently (Hajibabai, 2007;Song, 2016). Based on crowd rescue model, considering fire hazard on firefighters and fire damage of architectural component, the optimal rescue route can be searched to help the firefighter evacuate the trapped people (Kobes, 2010;Wu, 2012).…”

ABS TRACT:Building fire is a risky activity that can lead to disaster and massive destruction. The management and disposal of building fire has always attracted much interest from researchers. Integrated Virtual Geographic Environment (VGE) is a good choice for building fire safety management and emergency decisions, in which a more real and rich fire process can be computed and obtained dynamically, and the results of fire simulations and analyses can be much more accurate as well. To modelling building fire scene with VGE, the application requirements and modelling objective of building fire scene were analysed in this paper. Then, the four core elements of modelling building fire scene (the building space environment, the fire event, the indoor Fire Extinguishing System (FES) and the indoor crowd) were implemented, and the relationship between the elements was discussed also. Finally, with the theory and framework of VGE, the technology of building fire scene system with VGE was designed within the data environment, the model environment, the expression environment, and the collaborative environment as well. The functions and key techniques in each environment are also analysed, which may provide a reference for further development and other research on VGE.

“…There is considerable breadth in the range of theoretical approaches that are considered when modeling navigation and way-finding in these traditions. For example, models have been used to examine the economy of movement in retail streetscapes relative to particular points of interest [217], way-finding in emergency contexts with unfamiliarity and stress [218], the influence of errors and misjudgment on agents' way-finding [219], hierarchy in how information is stored and prioritized [220][221][222], and the role of affordances in weighting decisions [223]. Work in formalizing the concepts that these behaviors share as ontology is particularly well-developed [224,225].…”

Abstract:Streetscapes have presented a long-standing interest in many fields. Recently, there has been a resurgence of attention on streetscape issues, catalyzed in large part by computing. Because of computing, there is more understanding, vistas, data, and analysis of and on streetscape phenomena than ever before. This diversity of lenses trained on streetscapes permits us to address long-standing questions, such as how people use information while mobile, how interactions with people and things occur on streets, how we might safeguard crowds, how we can design services to assist pedestrians, and how we could better support special populations as they traverse cities. Amid each of these avenues of inquiry, computing is facilitating new ways of posing these questions, particularly by expanding the scope of what-if exploration that is possible. With assistance from computing, consideration of streetscapes now reaches across scales, from the neurological interactions that form among place cells in the brain up to informatics that afford real-time views of activity over whole urban spaces. For some streetscape phenomena, computing allows us to build realistic but synthetic facsimiles in computation, which can function as artificial laboratories for testing ideas. In this paper, I review the domain science for studying streetscapes from vantages in physics, urban studies, animation and the visual arts, psychology, biology, and behavioral geography. I also review the computational developments shaping streetscape science, with particular emphasis on modeling and simulation as informed by data acquisition and generation, data models, path-planning heuristics, artificial intelligence for navigation and way-finding, timing, synthetic vision, steering routines, kinematics, and geometrical treatment of collision detection and avoidance. I also discuss the implications that the advances in computing streetscapes might have on emerging developments in cyber-physical systems and new developments in urban computing and mobile computing.
