Why big data is required for future city planning

Japan is intertwined with many social issues, such as the concentration of large cities, the aging of the world in the world, and frequent natural disasters.

The creation of a city to solve those issues is required to be newly responded in addition to conventional city planning.One of the solutions to solve the problem is the use of big data.

For example, human -style data that attracts attention due to corona evil.It is a big data to know when, where, where, where to move, where, and how many people are there.By utilizing this human -style data, it will be possible to effectively formulate measures in fields such as traffic, sightseeing and disaster prevention.

In this article, Nobuyuki Sugimoto of Pacific Consultant Company, which produces city planning and other social infrastructure services, and Yutaro Tatsuno, who are involved in the DX business of urban and infrastructure at SoftBank Co., Ltd.We talked about how it would be useful for the plan.

From a large amount of infrastructure to the era of using infrastructure wisely

Sugimoto says that the concept of city planning is changing as time of the times.

"In Japan, infrastructure has been improved in accordance with the growth of population due to economic growth, the expansion of cities, and the spread of cars.Now, it has become a flow of maintaining existing infrastructure efficiently and using it effectively to improve the quality of urban services.

For example, the spread of transportation IC cards used on railways and buses makes it easier to accumulate data such as usage status than in the past, so that it can help improve station functions and services.Become.(Mr. Sugimoto)

On the other hand, Tatsuno says that it is important to monitor the city to use the city's infrastructure wisely and improve.

"For example, if you can statistically visualize human dynamics, you will be able to examine the necessary services and functions. Corona's evils have changed the way of thinking and the way of the city.What is required is a function that will be familiar with the services necessary for life.

In considering such services according to the actual situation of the city, I think that visualization of human -style data is an effective means.(Mr. Tatsuno)

Conventional statistical data is also required

It is essential to use big data such as human -style data for future urban planning, but statistical data such as census and personal lip survey * that has been used so far is also necessary.

* Person lip survey: Investigator visits and hearing a weekday transfer.It is implemented about once every 10 years, and you can understand what kind of attribute people have moved, where, where, and how means of transportation.

"Person lip survey is a small sample rate that captures one in 33 people to extract the population of the survey. Therefore, it was used to understand the rough movements because the detailed movement was not grasped.。

As with the census, I think these statistical data may not be able to reflect the latest information because the update frequency is 5 to 10 years.However, in the census, the "occupation" interviews "the purpose of transportation" such as whether it is a shopping or a job in the personal lip survey.

Occupation and moving purposes are the data required for urban planning, but it is difficult to grasp big data.In addition, in terms of looking at the changes in long -term span, it is not possible to find an increase or decrease unless these statistical data that exists from the past. "(Mr. Sugimoto).

Why human -style data is effective for city planning

So what are the benefits of utilizing human data?

Before exploring it, I would like to mention the EBPM recommended by the Cabinet Office (evidence -based policy draft).

The Cabinet Office explains that EBPM is "not relying on policy planning to an ascetic episode, but based on rational evidence after clarifying policy purposes."Analysis of human -style data and statistical data can be an effective means to derive the "rational basis" necessary to plan urban planning based on the concept of EBPM.

"In order to promote the city planning according to the evidence, human flow data that utilizes the location information of smartphones in addition to conventional statistical data.

The first reason is fresh.For example, human -style data of corona evil.The previous day's data is known the next day, so you can immediately consider countermeasures based on that information.Of course, it is difficult to consider countermeasures from the data if it is only the data before Corona.

The second is comprehensible.Today, when people's lives are diversified, there are issues and economies for each attribute such as where they live, age, and gender.To grasp those needs overall, you need a huge number of samples to grasp the dynamics of many people.

In addition, 24 hours a day, 365 days a year is required to monitor every day, taking into account the weather such as sunny and rain, but it is possible to comprehensively grasp these by using human -style data.(Mr. Sugimoto)

From now on, it can be said that it is important to plan big data such as human -style data while utilizing conventional statistical data.

Examples of measures that utilize human flow data

What kind of measures can be used for specific measures with highly fresh and reliable and continuous human data?Sugimoto says:

"For example, it can be used for transportation infrastructure development. Analyzing the movement of people in a certain region with human data, and if there is a certain person's traffic between certain facilities in the area, the demand will be taken in to incorporate the demand.In areas with high -distance movement needed in short distances, it can be considered, such as installing a means of transportation that allows consumers, such as a share cycle, can move freely when they want to move.

Next is sightseeing.By grasping the movement of tourists through human data, you can grasp the flow from tourism resources in the region.As a result, after visiting the famous spots at the point A, you will be able to use the specialty of the specialty of the B point B and to stop by a museum at the point C.As a result, we believe that it will contribute to tourism promotion of the entire region.

And disaster prevention.When a disaster occurs, you can statistically analyze the behavior of residents for each area.By grasping the movement to the shelter in chronological order by area, it will expand the efficiency of the area that has been evacuated efficiently, or identify the factors if the difference between areas is large.It is possible and can be used as a reference data for reviewing the local disaster prevention plan.(Mr. Sugimoto)

Urban planning to promote public -private collaboration by utilizing human -in -style data provided by private companies

It is a well -known fact that the spread of the Internet and smartphones has significantly increased the type and amount of information obtained.One of them is human flow data based on the location information of the smartphone.

The Ministry of Land, Infrastructure, Transport and Tourism has already promoted a data -driven society, but in many cases, private companies have necessary data.One of them is the nationwide statistics service that SoftBank developed in co -creation with Pacific Consultants.

The service provides statistical data based on Pacific Consultant's knowledge and know -how on social infrastructure such as urban planning and transportation plans, as well as the portable position information of Softbank, which was anonymously processed with license.It is a service that allows people to grasp the dynamics of 24:365 in Japan.

　"The data of" Nationwide Uroki Statistics "uses tens of millions of terminal location data based on data from SoftBank's mobile phone base station. The data is combined with various statistical data.We have estimated the total population of about 120 million people. I think that it is an effective data for urban planning in terms of the crowd, the freshness of the data, and the human attributes."(Mr. Sugimoto)

　"We believe that the future city plan is required to combine the government's statistical data and the big data of private companies to make measures and plans. The human -style data by" Nationwide Statistics "is specified as time and location.I think that it is possible to obtain data, so it is possible to first objectively grasp the current state of the area you want to know, and connect it to regional improvement based on the issues you can see from it.

　On the other hand, it is necessary to use the data effectively, not just to say that data is good.For that purpose, I feel that it is important to work together with companies that have knowledge of data analysis and experience points.(Mr. Tatsuno)

Urban planning has various fields, such as traffic, disaster prevention, tourism, commercial, education, and infrastructure.

And appropriate big data is being aligned in each field.For example, in sightseeing and commercial payment data, educational big data in educational companies in education.Under such circumstances, I hope that as a single consumer, the human flow data necessary for urban planning to live safely and securely in all fields will be used for granted.
