TOYOTA Project

Title: Design for next-generation mobility service in suburban areas
Industrial Partner: Toyota Motor Corporation and University of Tsukuba
Toyota will lead the way to the future of mobility, enriching lives worldwide with the safest
and most responsible ways of moving people. In the near future, cars are expected toconnect with people and communities and to perform in new roles as part of human social
infrastructure. New domains of service such as AI, autonomous driving, robotics, andconnected cars are becoming especially important. Toyota aims to reach the ultimate goalof sustainable mobility, creating a mobile future society full of smiles. Toyota and theUniversity of Tsukuba have jointly established the R&D center for strategic frontiers insocial planning (F-MIRAI), which advances toward Society 5.0 through the development of
infrastructure for future communities and the formation of industrial centers through longterm collaborative action.

Background:
Rapid suburban sprawl in metropolitan areas in Japan has led to the rapid development of
peripheral satellite cities. High-speed railway networks and motorways have contributed
considerably to improving connections among established metropolitan areas and thesenew peripheral cities. Nevertheless, rapid population growth has led simultaneously toconstruction of suburban sprawls without any schematic road planning.

Consequently, key functions of cities for the daily life of residents, such as commerce,administration, and schools, have diffused to suburban areas on the basis of widening useof private cars. Such development is neither sustainable nor desirable as populations age

and as energy conservation becomes increasingly important. In principle, a higher quality oflife can be achieved if key city functions are aggregated in city centers around main railwaystations. This aggregation necessitates the adoption of better and more efficient public
transportation networks in conjunction with small devices used for personal mobility.
Mobility-as-a-Service (MaaS*) describes the integration of different transportation modes toachieve mobility solutions that are consumed as a service. Mobility innovation can beimplemented fully or partially as MaaS and Smart Cities. Its principles are often designatedas the following: C, Connected; A, Autonomous; S, Sharing; E, Electric (CASE). A wider
range of demonstration programs and commercial services is being provided to improvetransportation safety, efficiency, and convenience. In particular, “IoT vehicle information” isanticipated for application to widely various services because it aggregates various
information related to local transportation in an immediate, remote, and wide-area manner.
The benefits of using IoT vehicle information with AI to meet transportation challenges andsupport local economic growth are important.

* MaaS: integration of various forms of transport services into a single mobility service thatis accessible on demand. To meet a customer’s request, a MaaS operator provides adiverse menu of transport options, be they public transport, ride-, car- or bike-sharing, taxi
or car rental/lease, or some combination thereof. For the user, MaaS can offer added value
through use of a single application to provide access to mobility, with a single payment
channel instead of multiple ticketing and payment operations. For its users, MaaS isexpected to be the best value proposition, helping users meet their mobility needs andsolve the inconvenient aspects of individual journeys as well as the entire system ofmobility services.

problems in widely diverse areas such as administrative services, transportation, medical
and nursing care, and infrastructure, using advanced technologies such as ICT and otherdata to create a sustainable citizen-centered city in which everyone can live safely,conveniently, and comfortably.

Project and Expectations
Many studies and demonstration experiments have elucidated MaaS as an implementationof CASE, particularly for metropolitan areas where other multiple transportation modes
such as rails, metro, and buses are available. Nevertheless, other areas for which private
cars constitute the dominant transportation mode have not been investigated thoroughly.
Mobility services for non-metropolitan areas can differ from those for metropolitan areas
because of differences in population density/distribution, transportation demand, and public
transportation networks. As an example, Tsukuba city, a city with a population of 241,000
people, and located 60 km northeast of Tokyo, has a transportation system that isdependent on private cars. However, Tsukuba city was designed as a science city suchthat the University of Tsukuba, which also has a hospital, is positioned as the center of its
urban function. Therefore, MaaS centered on the university can be a good example of afuture transportation system in a non-metropolitan area.
This project will design MaaS for practical cases for the campus of University of Tsukuba
through analyses of person-trips and other related datasets. The present majortransportation modes around the university are private cars, buses, bicycles, and walks.
The services accompanied with mobility around the campus are various, ranging fromeducation, health care, and nursing care, to childcare. Participants are expected toestimate the overall transportation demand to optimize those services through analyses ofavailable datasets, and to build a mathematical model as a system-of-systems based onsome of the following perspectives. All can be considered with automated vehicles.
 Travel planning with online booking systems.
 Traffic prediction and forecasting and dynamic traffic control.
 Minimizing energy consumption for travel.
Although several approaches for such problems already exist, participants are expected tofind completely new mathematical approaches, descriptors, formulations, solvers,visualizations, operation plans, etc. to accommodate and support our future society withhighly sophisticated modes of mobility. Additionally, investigating the energy expenditureand traffic flow of cars in terms of dynamical systems theory is possible by implementing
mathematical models into automated vehicles in a miniature traffic course on a trial basis.
