Integrated analysis of environmental qualities and pedestrian movement using simulations

Abstract

Pedestrian simulation models typically focus on interactions with physical objects, while neglecting environmental factors such as solar radiation, which can significantly influence outdoor movement behavior. This paper introduces a novel framework that integrates environmental qualities, particularly sunlight exposure, into pedestrian movement simulations to support urban design. Using tools such as Rhinoceros/Grasshopper and the Ladybug plugin, solar radiation is evaluated and incorporated into routing algorithms that model pedestrian preferences based on environmental comfort. The results demonstrate enhanced flexibility in modeling movement choices and the ability to assess urban design options in terms of spatial and environmental qualities. This approach facilitates datadriven collaborative urban planning processes by linking environmental analysis with pedestrian simulation.
