Q&A List

The answers to the questions we received on the day and in the follow-up survey are as follows:

QPlease let us know the details of the information that can be understood from the collected people flow data (tracing individual behavior, recognizing attribute information such as gender, counting people, etc.).

A

Common answers for all areas
In all areas, we collect data in compliance with relevant laws and regulations such as the Personal Information Protection Act.

OMY Response
We have formulated a sensor management policy for this area, and are conducting various demonstration studies and experiments while exploring the optimal placement of various sensors in the area and taking advantage of the characteristics of each device, such as cameras, beacons, and Lidar. Therefore, at this time, we are not narrowing down to a specific method to regularly measure people flow. In addition, we believe that the data collected will differ depending on the use case set, and the presence or absence of attribute analysis and behavioral tracing will be in accordance with the purpose of the demonstration.

Takeshiba’s Answer
In the Takeshiba case, the target is security cameras installed in city blocks. The data collected is on the number of people, gender, and age, without identifying (tracing) individuals.

Toyosu Answer
The attribute data acquired varies depending on the method of data acquisition and analysis. When acquired by a camera, the data is people flow data that includes gender, age, and other attributes. When acquired by a packet sensor, the data shows congestion and movement within an area without acquiring attributes. In addition, the data is at a level that cannot trace individuals.

Nishi-Shinjuku Answer
The people flow measurement cameras installed on smart poles in the Nishi-Shinjuku area collect the following data:

• Number of pedestrians passing in front of the smart pole on the sidewalk, direction of travel, attributes (gender and age), whether they are wearing a mask, number of people staying there, and number of seconds they stayed there
• Number of people in front of the digital signage, number of people in the viewing area, number of people who saw it, gender and age attributes, and viewing time

Furthermore, images captured by people flow measurement cameras are instantly converted into numerical information such as the number of people passing by, and any images that could identify individual pedestrians are immediately discarded. Further details are provided below.
