Wayfinding Simulation of Sign Layout in a Public Square by a Vision-Driven Pedestrian Agent in a Virtual Space Yoji Yokoyama, Yotaro Maekawa, and Toshiyuki Kaneda
Abstract In this study, we conducted a sign layout survey and a pedestrian trajectory survey in Toyota City station square to explore the characteristics of pedestrian trajectories, focusing on the attributes of pedestrians. In the theory of wayfinding, it is important to consider the navigation of pedestrians. The VD18s, a vision-driven agent, was applied in a simulated space made using the game engine Unity. We perform a pedestrian simulation using a model of the Toyota City station square based on two surveys. This is a site where people move between Toyota Station (of Nagoya railroad) and Shin Toyota Station (of Aichi Loop railway). We examined the behavior of actual pedestrians, not only on weekdays but also on weekends/ holidays during special events. Based on the analysis of the results, we consider the sign arrangement of the Toyota City station square. We conclude that vision-driven agent simulations can be used as a tool to support sign planning. Not only in the square but also in the other mid-scale urban spaces, this kind of agent simulations can be effective approach for both theory and practice.

Introduction
Sign planning (in terms of sign layout and design) in public area is important for the planning and management of lively (crowded) small-to-mid-scale urban spaces. As the information on signs tends to be evaluated impulsively, the planning of signage Y. Yokoyama Toyota City Office, Nisimachi, Toyota, Aichi, Japan e-mail: [email protected] Y.

needs to consider several aspects: (1) the convenience of the shortest walking route; (2) the safety of the space at busy times; (3) the comfort of the walking space itself; and (4) avoiding cognitive overload and promoting cognitive consonance with the information presented. This list clarifies that sign planning is more than a simple optimization problem. The basic question of sign planning is how to guide navigation for pedestrian users. In other words, what positioning should planners choose to aid the navigation of a wide variety of pedestrian users? Therefore, the concept of a complex system in which the intersection between the intentionality of the various users and the intentionality of the sign planner is significant. Furthermore, if we are conscious of the theoretical scope, this can be said to be a problem involving users’ spatial cognition, especially on the theme of wayfinding. Wayfinding is “the process of determining and follow
