IoT controls our environments. That includes environments of each individual residence and individual office, as one of many areas that IoT controls. The collection of those environments is the city environment.

Current city environment has following issues in many areas;

  • Issues caused by lack of resources due to population concentration
  • Advanced transportation service
    • solution for traffic jam
    • car or bicycle sharing
  • Environmental issues
    • water pollution
    • air pollution
    • regional initiatives for energy saving
  • Disaster prevention
    • flood control for torrential rain
    • how to guide people to evacuate in case of flood disaster, earthquake, hurricane, etc.
  • Allocation of safe environment
    • security enhancement including counter-terrorism, etc.

For the issues as above, approach of smart city is to find solution and clues, making effective use of big data analysis, government and public open data.

YRP UNL has conducted research and experimentation, applying outcome of research activities of IoT and various open data offered by ODPT

Case Study 1: (City Platform as a Service, integrated open) was a project to develop a software platform that can be used to solve urban issues that cities in the EU and Japan face today by mean of the IoT. The project started in July 2016 officially as an EU-Japan collaborative project.

Sponsors / Members

Project funding is done by EU Horizon 2020 project on the EU side, and is done by National Institute of Information and Communications Technology (NICT) on the Japan side. The project spams 30 months from July 2016.
E-Government Institute of Bern University of Applied Sciences was the EU coordinator and Japanese coordinator was YRP Ubiquitous Networking Laboratory.

Design Philosophy

EU partners used FIWARE for the reference implementation of IoT application architecture while Japanese partners used IoT-Aggregator (u2 architecture). FIWARE has been used widely as an infrastructure of the IoT applications and has become an important pillar along with the Japanese IoT-Aggregator in the project.
The project has designed and developed the architecture by combining cloud services and embedded devices including sensors.

 Case Study 2: Prototype Experiments / Use Cases

Prototype experiments have taken place in cities to learn the requirements of cities and to validate the effectiveness of the architecture.

In Japan, tourism support in Sapporo, emergency medical care in Yokosuka and public transportation in Tokyo are three targets. “Open Data Challenge for Public Transportation in Tokyo” contest held by the Association for Open Data of Public Transportation (ODPT) uses the technology based on design philosophy and framework (vocabulary, data structure, API, etc.)

In Europe, sewage water control after heavy rain in Amsterdam, and event management of “Color Run,” parking space management in Murcia (Spain) have been tried.

The last year of the project, 2018, saw experiments that connect the EU and Japanese instantiations of There the recently highlighted private data management issues (exemplified by EU’s GDPR) posed practical problems.
Effectiveness of’s dashboard was confirmed there.

Case Study 3: City Stakeholders Meetings

In order to learn the requirements from city governments and to promote the project, City Stakeholders meetings have been held twice in Japan (Once at 2017 TRON Symposium and 2018 TRON Symposium) and once in the EU. A panel session was held at 2018 TRON Symposium. At the 20178 TRON Symposium, the representatives from Amsterdam, Murcia, Sapporo, Tokyo, Yokosuka, and Zurich presented their views and exchanged opinions. At the symposium, Tokyo had a special session dedicated to it to discuss its pressing issues related to Tokyo Olympic and Paralympic Games in 2020.

The support from these city governments is essential for the deployment of the project’s result. TRON Forum members have worked with the ODPT, Sapporo Open Data Association, etc. and these past activities have turned very useful for

Project Summary and Future 

The 30-month project will end at the end of December 2018.A Japanese whitepaper that summarizes the prototype use cases will be published at website.
