The International Conference on Pedestrian and Evacuation Dynamics is carried out biennially by scientists interested in pedestrian and evacuation movement.The field of pedestrian movement and evacuation dynamics is an interdisciplinary discipline. The modelling of evacuation and pedestrian dynamics has evolved from calculations based entirely on physical processes e.g. granular flow, to simulation that now begins to include psycho-social processes accouting for limited decision-making and group behaviour. Given projected demographic changes, the diversity of the evacuees and pedestrians populations and their capacity to achieve objectives has become increasingly important. Accessibility and egressibility, and the relationship between them, has therefore moved to the fore. This is further complicated as a building is used according to a number of management concerns as safety, security and operations, that are employed under different scenarios -emergency and non-emergency. The need for analysis to assess the effectiveness of management procedures is therefore significant and expanding. Pedestrian and Evacuation Dynamics welcomes contributions of physicists, mathematicians, engineers as well as psychologists and sociologists with an interest in the description of small and large groups as well as individual pedestrians and evacuees. The PED conference focuses on the modelling of people movement during emergency and non-emergency scenarios. This modelling may range from enhancing our understanding such movement, the development of conceptual models, to the quantitative assessment of such movement, the development of engineering or computational tools. The applications of interest range from small domestic settings to the movement of thousands of people. The research objectives and applications may vary; however, the common intention is to aid in our understanding and/or assessment of pedestrian movement under emergency or non-emergency scenarios.PED is a therefore a conference, with a focus on the development of models that describe pedestrian and evacuee dynamics and the various activities that support this development: data collection, model development, model application in novel areas, using new techniques and the employment of the results gained in innovative ways.Citation:Please cite the full conference proceedings as follows:Dederichs, A., Köster, G., Schadschneider, A.; Proceedings of Pedestrian and Evacuation Dynamics 2018, Collective Dynamics, A26, 1-442 (2020).
