常态行人运动仿真研究综述OA

Pedestrian movement simulation is an active area of research in computer graphics,with significant applications in public safety management,urban planning,and intelligent transportation.This paper provides a systematic review of relevant studies since 2020 on pedestrian movement simulation under normal conditions,examining the characterization of pedestrian dynamics and key model-building components.Pedestrian dynamics are characterized through speed-density relationships,level of service,fundamental diagrams,and mobility models.Moving beyond conventional modeling approaches,this study focuses on model elements,analyzing the characteristics,suitable scenarios,and limitations of different modeling methods from psychological,decision-making,and environmental perspectives.Finally,it identifies current shortcomings in pedestrian movement simulation models and suggests directions for future research.
