Can Walking Behavior be Predicted?: Analysis of Calibration and Fit of Pedestrian Models

Several models for simulation of pedestrian movement have been proposed in recent decades. These models are primarily used in the planning and evaluation of large pedestrian infrastructures, such as transportation hubs, with a focus to increase comfort and safety for pedestrians. Although the number of proposed simulation models is increasing at a fast pace, not much is known about the properties of calibration procedures or the transferability of the models estimated in one setting to other settings. This paper compares three calibration methods for a slightly adapted social force model. The main emphasis lies in the characteristics of the data-generation process and the information contained in the data sets. The sensitivity of the model parameters of the calibrated model were investigated, and the transferability of the model to different scenarios was tested. Results revealed that the quality of the data had a strong effect on the suitability of different calibration strategies and that the information content in the scene under investigation limited the transferability of the results to other scenarios. These results suggest that several data sets with different characteristics do not need to be included in the calibration process to achieve a model that performs well in a wider variety of settings.

Simulating pedestrian movement in dynamic environments

Agent-based simulation offers multiple advantages when dealing with complex phenomena like pedestrian movement, characterised by a possibly large number of locally interacting entities. The main goal of this article is to illustrate this key point, from the simulation of pedestrian movements in confined designed spaces. It specifically focuses on the formalisation of space and of agents populating it. The model developed, MAGE, allows exploring the role played by local interactions on the global dynamic of the designed spatial system.

Interactive Space Generation through Play Exploring the Role of Simulation on the Design Table

In this paper we report on recent developments in the use of simulation as an aspect of design decision support for architecture and planning. This research is based on ARTHUR (Augmented Round Table for Architecture and Urban Planning). Although real time simulation has been incorporated in design support systems, little attention has been given to the simulation of pedestrian movement in collaborative AR based systems. Here we report on user evaluation tests of the ARTHUR system, which are focused on the effect of real time pedestrian simulation on the way pairs of designers work together. These tests suggest that the integration of simulated pedestrian movement on the design table plays a critical role in exploring possible design solutions and encourages different and new ways of thinking about design problems. Donald Schon's concept of the reflection-in-action provide a useful framework for interpreting these results.
