Start of Joint Research about Public Transportation Diversity and HealthJapan System Techniques Co., Ltd. (Head office: Osaka; Representative: Takeaki Hirabayashi, President and CEO; JAST)and Kento Yoh, an assistant professor at the Osaka University Graduate School of Engineering (Location: Suita-shi, Osaka,President: Shojiro Nishio), have started a joint research program to determine how increasing the diversity of public
transportation affects the health of residents of the area served by this transportation by using medical big data.
This joint research program is part of the COI-NEXT program for supporting the formation of co-creation hubs. Osaka
University was selected to participate in the regional co-creation field of COI-NEXT, which includes the Futuristic andIntelligent Infrastructure Co-Creation Center theme. This joint program will work on the second research and development
theme: the development of methods for co-creation encompassing the private, academic and public sectors as well as thepublic with the goal of creating urban infrastructures centered on residents.
◼

The Joint Research ProgramThis program aims to examine specific areas to determine the correlation between public transportation diversity indicators *1
and medical expenses of residents in these areas. Evidence will be gathered concerning the Osaka University COI-NEXT
theme of assessing the health benefits of transportation centered on local residents. Activities will study benefits inmunicipalities and junior high school districts in the northern part of Osaka prefecture. JAST’s medical big data will be used
to obtain information for analysis concerning the relationship between public transportation diversity assessments and medical
expenditures and the number of medical examinations for specific diseases.

COI-NEXT

COI-NEXT (Program on Open Innovation Platforms for Industry-Academia Co-Creation) is a program of the Japan Scienceand Technology Agency that is conducted by institutions that were selected for participation following an application process.
One part of the project is research and development for innovations that use backcasting for creating a vision for centers that
help accomplish the Sustainable Development Goals. The other part is the establishment of a co-creation system encompassing
the private, academic and public sectors that has the objective of establishing centers that are self-reliant and sustainable. COINEXT has different sites for individual fields of this program, such as the regional co-creation field and the policy priority
field. There are 42 sites throughout Japan, including 30 full-scale sites and 12 fostering sites. Osaka University is a site forfour fields of COI-NEXT. JAST is participating with this university in the regional co-creation field regarding Futuristic andIntelligent Infrastructure Co-Creation Centers.

NEWS RELEASE*1 Public transportation diversity indicators
Public transportation capable of improving the lives of the public requires more than simply a network of services. The
diversifying needs of the public concerning transportation also demand a variety of methods for going from place to place.
Professor Doi and assistant professor Yoh of the Osaka University Graduate School of Engineering are creating public
transportation diversity indicators for the purpose of evaluating new public transportation services and regional services bylooking at the types of services available in individual areas.

*2 Health insurance invoices
When an individual receives a medical treatment covered by insurance, the healthcare institution sends an invoice listing theprocedures and amounts due to the insurance company or organization. For medical and dental care, an invoice listing theprocedures and amounts due is sent. For pharmacies, an invoice listing the drugs supplied and amounts due is sent. For nurses
visiting individuals at home, an invoice listing home nursing care services and amounts due is sent. One invoice for eachpatient and individual healthcare institution is prepared every month. Invoices contain information about the reasons thatindividuals received medical care, the cost of the care and other items. JAST converts this information into a database forsubsequent utilization.
