Abstract
Guidance signage placement is a fundamental operation for crowd control in public places. The current methods mainly rely on manual design or mathematical models, which are not flexible and effective enough for crowd control in large public places. To address this issue, this article proposes a multiobjective evolutionary framework that can search for high-quality guidance signage placement strategies automatically. In the proposed method, an agent-based crowd simulation model is proposed to simulate the wayfinding behaviors of pedestrians in public places. Furthermore, a new safety metric is proposed to quantitatively evaluate the quality of guidance signage placement strategies. On this basis, an indicator-based multiobjective evolutionary algorithm (IBEA) is utilized to search for optimal guidance signage placement strategies that have tradeoffs between crowd safety and pedestrians’ travel time. Simulation experiments on both synthetic and real-world scenes were conducted to evaluate the proposed method, and the simulation results show that the proposed framework can generate very promising guidance signage placement strategies in comparison with several existing methods.
期刊介绍:
IEEE Transactions on Computational Social Systems focuses on such topics as modeling, simulation, analysis and understanding of social systems from the quantitative and/or computational perspective. "Systems" include man-man, man-machine and machine-machine organizations and adversarial situations as well as social media structures and their dynamics. More specifically, the proposed transactions publishes articles on modeling the dynamics of social systems, methodologies for incorporating and representing socio-cultural and behavioral aspects in computational modeling, analysis of social system behavior and structure, and paradigms for social systems modeling and simulation. The journal also features articles on social network dynamics, social intelligence and cognition, social systems design and architectures, socio-cultural modeling and representation, and computational behavior modeling, and their applications.
