Towards a Validation Taxonomy for Agent-Based Models of Pedestrian Movement in Cities (Short Paper)

Authors: Marcin Wozniak and Gabriele Filomena

Published in: LIPIcs, Volume 393, 17th International Conference on Spatial Information Theory (COSIT 2026)

Abstract
Agent-Based Models (ABMs) are increasingly used to simulate and analyse pedestrian movement in cities and to support urban planning and policy decisions. However, their credibility depends critically on rigorous empirical validation, for which no standardised framework currently exists. This paper addresses this challenge by providing a structured synthesis of existing validation strategies, tailored to ABMs of pedestrian movement in cities, focusing on the comparison of simulated and reference behaviours. First, it reviews and systematises operational validation approaches spanning three model output levels: micro, meso, and macro. Then, it develops a validation taxonomy that links specific model outputs - individual behavioural trajectories, segment-level flows, and aggregate system indicators - to data sources, potential validation methods, and appropriate behavioural claims. Finally, it demonstrates the implementation of these approaches using illustrative examples. Here, it is argued that not only do different model outputs require distinct data sources and methodological strategies, but the generalisations a validation exercise can support are bounded by what is validated and how. The paper advances a practical validation taxonomy that, whilst setting standards in the discipline, can be flexibly adapted to diverse modelling contexts. In doing so, it supports the development of more robust, transparent, and policy-relevant agent-based models of pedestrian movement in cities.

Route Choice Through Regions by Pedestrian Agents (Short Paper)

Authors: Gabriele Filomena, Ed Manley, and Judith A. Verstegen

Published in: LIPIcs, Volume 142, 14th International Conference on Spatial Information Theory (COSIT 2019)

Abstract
Simulation models for pedestrian movement are valuable tools to support decision-making processes in urban design. However, existing models of pedestrian behaviour are built on simplistic assumptions regarding people’s representation of the urban space and spatial behaviour. In this work, a route-choice algorithm that takes into account regionalisation processes and the hierarchical organisation of geographical elements is adapted for pedestrian movement and incorporated into an agent-based model. The macro-level patterns emerging from two scenarios, one employing an angular-change minimisation algorithm and the other employing the regional algorithm here proposed, are compared for a case study in London, UK. Our routing algorithm led agents to recur to a higher number of street segments, i.e. routes were more diverse among agents. Though validation has not yet been performed, we deem the patterns resulting from the regional algorithm more plausible.
