This work aims to make a theoretical and practical contribution, putting the discussion of a new public transportation design into a single SoS and generating the value according to the service-dominant logic. To date, to the author’s knowledge, previous studies have mainly discus
sed the sharing of services or collaboration in the transportation system, not framing the conc
ept into the SoS.
The dissertation consists of the following chapters.
Chapter 2 designs regional and rural public transportation through the approach of thesystem. It considers how to incorporate individual systems that already exist, each of which
is discussed in terms of users, suppliers, and general public. Each "system" featured in this thesis is discussed. The design of the system adds logical validity based on the service-dominant logic. We also look at the relationship between the subsequent chapter data and the method
ologies that will support this structure.
Chapter 3 explores users' heterogeneity when sharing a vehicle's space. It is assumed t
hat the transportation service transports passengers and freight together within a vehicle to exp
and the insufficient demand in rural areas, although the space of the vehicle may also be bet
ween multiple passengers. In this case, the heterogeneity of the user is further accommodated
in the vehicle. A stated preference (SP) survey for conventional buses and integrated (mixed)
transportation was conducted in Iwami town in Tottori prefecture, a rural area in Japan. With
that survey data, this chapter explores people's preferences and their heterogeneity are classifi
ed with different Value of Time (VOT) using latent class modeling. This measures the value
when the space of the vehicle is shared.
Chapter 4 discusses the optimal operating direction when users with different VOT discussed
above use integrated transportation. In addition to reflecting the value of heterogeneous people in theoperation of vehicles, the heterogeneity of freight is also considered in addition to considering humanheterogeneity by classifying rural freight as fresh goods and general goods. In addition to the VOT
obtained from the data in Chapter 3, the synthetic demand is set by considering the public
transportation utilization ratio, destination, and time zone obtained from the survey, and simulated
through the vehicle routing problem with time window (VRPTW). The purpose function of theoperation is to increase the utility of the users while considering the heterogeneity of the users, and it
is also assumed that passengers gather at the meeting point to increase the efficiency of the operation.
This leads to a discussion on the social value of sharing the space of the vehicle.
Chapter 5 moves to the operator's point of view and discusses how multiple operators
can transition to a new business through new technologies and services. In this case, the ope
rator of the taxi which is providing door-to-door services was explored, and an SP survey was conducted on whether to provide the operator with a new business model combining new technologies and services and business development implementation. Through this, we looked at
the barriers to the process of moving to a new business model and what can be a catalyst to transitioning to a new business model. This study was conducted in areas where demand inJapan is expected to decrease (i.e., Chugoku region). The heterogeneity of preferences was e
xamined at the municipal level through classification based on Japan's local autonomy law an
d population.

Chapter 6 extends the discussion from existing "traffic services" to new transport servi
ces and their surrounding infrastructure and sets a stakeholder as a general public, not only service users but citizens. The new transportation service, especially the service where new tech
nologies are introduced, no longer acts as a service itself but affects several people, such as
people in waiting places for public transportation and pedestrians walking around the system.
When designing these services, we expand the discussion to create a transportation environme
nt where the general public wants to live the most safely, discussing the system when transpo
rtation shares space with the general public. The study involved a survey on the people’s pref
erences when a new technology that connects trams and buses on public transport is introduce
d to the general public in Hiroshima city and discusses ways to improve the acceptability ofthese new technologies. By considering the general public's preferences, this result will help design a safe way to share limited spaces around public transportation.
Finally, Chapter 7 summarizes the findings of each chapter and does a cross-case anal
ysis to propose a prototype of the System of Systems with multiple stakeholders’ roles. The limitations and the further expected research are also discussed.
