IATSS Research Project Reporting
Projects Introduction
2207A ProjectDevelopment and Implementation of a Program forTransforming Traﬃc Safety Behavior in Cambodia《Background and aims》
As developing countries in Asia undergo rapid economic growth, motorisation, and the development ofmajor national roads, people in suburban and rural areas are suﬀering more traﬃc accidents as bettertransport infrastructure allows drivers to travel at higher speeds. Similar problems aﬀect Cambodia withimprovements of National Road 5, which prompted transit safety education and behavioural change
programmes as government action plans, and the start of the JICA Transport Safety Technology
Cooperation Programme.
A behavioural change programme team started as a collaborative project of the IATSS Forum, Cambodia
IATSS Alumni Association (CIAA), and JICA. Based on recent local data and trends in behaviouralchange theory, a novel and interdisciplinary conceptual behavioural change programme and survey
methods (of school and pre-school-aged children) will be developed in preparation for implementation withthe team.

Survey on traﬃc safety education and commuting by interviewing and video-surveying local elementary,middle,and high schools.
● Constructed a behavioural change hypothesis based on the newest behavioural modiﬁcation models
and implemented a pilot study to collect data on the behaviours of students before implementing theprogramme.
●●⇒Completion of preparatory steps for implementing the programme the next year
The behavioural change programme and impact assessment method were developed, as well as
implemented and evaluated at several middle schools located on National Road 5.
● Planned a sustainable support system led by the local team.

2203C Project

Development of Walkable City Assessment Method《Background and aims》
The rapid population decline and ageing in Japan has urged urban areas to be redeveloped into compact cities. However, making cities compact alone is
insuﬃcient, as the appeals and activities of cities must continue to thrive. Plans for city redevelopment that encourage a comfortable and walker-friendly
downtown has been proposed by a committee organised by the Ministry of Land, Infrastructure, Transport, and Tourism (MLIT) in 2019, and was formally
started as the Walkable Downtown Promotion Programme in FY2020. Currently, 346 cities in Japan（as of end of Jan, 2023）have come forth aspromoters of walkability. This study aims to elucidate methods for cross-sectional evaluations of walkable cities in Japan using examples in European andAmerican cities as models.

The perspective of walkability assessments may and should be modiﬁed according to the outcomes
set as goals responding to social challenges.
A walkability index can be organised by social, economic, or environmental sustainability, health, and city,and may also depend on the scale of the space.
A walkability index can be categorised by methods using an objective or subjective approach, andnewer methodologies are also proposed.
This study researched examples representing sustainability, health, city, spatial scale, and objective andsubjective methods, as well as proposed additional new methodologies.

The MLIT is assessing city walkability by subjective methods at district levels, but also plans toexperiment with a mixed method that combines it with the objective and novel methods explored inthis study.

Outlook●We aim to publish the results of research to date and implement the use of this assessment method withthe cooperation of the MILT.

FY2022 Local surveys

2208C ProjectStudy on the development of a safe andcomfortable road environment under mixed electric mobility
Small electric (e-) mobility devices such as electric scooters have been introduced in Europe
and the US, and are similarly anticipated in Japan for transport support and travelling the Last
Mile. This study performs multifaceted analysis of user psychology and behaviours, safetyassessments, and legal systems to identify the challenges associated with the safe andharmonious introduction of new e-mobility devices with existing means of transportation, andseeks to discuss road rules to achieve it.
Activities for this study were conducted in six working groups ( WG). WG1 performed aninternational comparative survey which showed that the structure of awareness may diﬀer
according to the level of popularity of e-mobility, and that developing legal systems and improving
operation services will increase social acceptance, especially in the transition period. WG2
discussed the survey of legal aspects to identify the challenges of ensuring safety education andparking, for example, for users without a driver s license. WG3 and WG5 examined surveys on
e-scooter safety and potential problems that are of concern based on user behaviours, anddiscussed safety measures for mixed traﬃc on sidewalks and roads, as well as road structures.
WG4 conducted a survey on local governments, and showed that the t ype of e - mobilit ydemanded diﬀers depending on community objectives. WG6 held an international workshop to list
topics of interest for the promotion of micro - e-mobility in Japan with reference to previous
attempts in European cities.

2220 Project (Social Responsibility)

Providing information on the actual situation andcase studies of roundabouts in Japan based on thedatabase development《Background and aims》
Over the last two years, the International Association of Traﬃc and Safety Sciences (IATSS) Survey
Project has re-structured the database (DB) of 100 items on the 140 round-abouts (RABs) in Japan and ofcase data to describe the history, introduction, and consensus-building related to R AB, and thecharacteristics of their applications, structures, and challenges. This project aims to hold seminars anddevelop websites based on these ﬁndings to provide information on Japanese RAB and numerous interestingcase studies. Information on real-world needs and challenges will be collected through opinion exchange inseminars to provide feedback on the DB content. IATSS will accomplish its roles in social responsibility
through these activities aiming for the favourable widespread introduction of RAB that contribute to roadsafety and sustainable city-building.

《Outline》

Spatial distribution of RAB in Japan

Developing a website of RAB DB

While an increasing number of RABs are being introduced in various parts of Japan, the data and whole
picture of RABs in this country were unclear. We made it possible to become aware of examples ofintroduction in Japan by developing an RAB DB and online publication system. Providing data on geometricstructures and good examples through this system is expected to demonstrate the eﬀective application ofthis support tool for RAB planning and design at various locations.
A lecture and poster presentation on the achievements of this project was conducted at the Round-About
Seminar in Nagai held in Nagai City, Yamagata Prefecture. Furthermore, a seminar titled Round-Abouts forEﬀective City and Community-Building was held in Kumamoto City for more information sharing and opinionexchange. These events reaﬃrmed the importance of persistently disseminating information on challenges
associated with the introduction of RABs and solutions for them to accelerate the widespread use of RABs.
