This blog is dedicated to BigClouT field trial to be conducted on the behalf of Fujisawa City and NTTE.
Fujisawa City is interested in using BigClouT platform for developing tourism besides the Tokyo Olympics Games 2020 venue.
The BigClouT project just started July 1st 2016, here is the timeline for defining the first set of use cases and field trial.
- September – December 2016: Use cases definition
- January 2017 – June 2017: Field trials preparation
- July 2017 – December 2017 : Field trials deployment and evaluation
- August 2018 – December 2018 : 2nd Field trials deployment and evaluation
If you want to share ideas or be involved in the definition and validation process, please contact us!

MinaRepo Trial (2016/10 ～ )
- Synopsis of trial
This trial aims to experiment with the BigClouT advantages for involving people in city sensing – often referred to as user-in-the loop sensing or participatory sensing. Especially, we perform two trials for two group of people – city administrative officers and citizen. Each group has each own character and issues to be solved for involving them to the city sensing. We explain each trial as following:
MinaRepo – Leveraging city officers as sensor
The purpose of first trial is based on two questions –
- can BigClouT platform improve daily city operation? and
- can BigClouT platform collect comprehensive city data to better understand the city?
City officers have daily works, for example garbage collection, road management, environmental management, etc. In those works, they have to collect/share city information. Currently, city staffs usually use legacy technologies such as telephone or FAX to collect/share such information. However, using such old technologies is not the best way for collecting/sharing information. It is sometimes inefficient and information is not stored as analysis-ready format (they usually use paper document to store the information). In this trial, we enhance their daily work more efficiency, and combines with city sensing opportunity.
By integrating their daily works with city sensing, large amounts of useful data can be collected every day. We call such piggyback sensing on the daily work of city employees Expert Crowd Sensing. In addition, city employees are expected to have more task specific knowledge of the city in which they are working than general residents. For example, garbage collectors, who daily travel through their assigned area, should be knowledgeable about the whole area and could detect subtle changes in a city. Consequently, expert crowd sensing enables us to acquire more accurate human sensing data with greater sensitivity. To achieve expert crowd sensing, a sensing tool must satisfy the following requirements:
-Easy integration with the daily responsibilities of city employees: To enhance their daily work by such sensing, the tool must not disturb their current daily activities and must efficiently support them.
-Easy usage: Since most city employees are not information technology experts, our tool must be easily understood and simply leveraged.
-Providing reliability, dependability, and security: The tool must be used in daily city functions, which sometimes provide critical services for citizens. Reliability and dependability are also needed for it. Since city tasks often deal with the private data of citizens, data must be securely protected.
We implement a system called MinaRepo to fulfill the above requirements by using BigClouT platform. As shown in the Figure 1, in MinaRepo, city staff possess smart devices. When they find city information they wish to share among other officers, they open MinaRepo application and take a photo of the information. Then, they post the report with some explanation to MinaRepo server. Finally, city officers can recognize latest city information and make a plan to deal the information (if necessary). We have tested a first prototype of MinaRepo with garbage section in Fujisawa city. In the second year, we plan to provide MinaRepo to further sections, and/or even other cities such as Chigasaki city or Samukawa city. By collaborating with other cities, we evaluate MinaRepo’s advantage more clearly.
