Proposal for an automated method for activity surveys using multimodal models

Abstract

The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) has set a new urban policy to create people-centered spaces in the city where people feel comfortable and want to walk around. In order to achieve this, it is necessary to evaluate the comfortableness of public spaces, but this task is carried out by manual survey, which is problematic because it requires an enormous amount of labor.

In this study, we proposed an automated method for surveying the comfort of public spaces using a multimodal model. To confirm the validity of the proposed method, we compared the accuracy and effort of the survey with a visual survey. Based on the validation results, we discuss the applicability of the pro- posed method to actual work and future issues.
