What is ‘Smart’ City

• City which has A&R: Awareness and Responsiveness

– Awareness: Understand/Predict City in Real-Time

– Responsiveness: Change city’s functions/behaviors according to it’s

situation

Boot the Smart Cityby maximize utilization of existing city assets

• Public Cars as Sensors

• WEB as Sensors

• Crowd as Sensors

How can we collect/share massive city data

in a sustainable way ?

Not only for rich cities - for Any Cities

Example:

Fujisawa City, Japan

1. Public cars as Sensors Garbage trucks go around entire city everyday

Spatially full-covered environmental sensing

1. Public cars as Sensors

Leveraging daily-use public cars for city sensingWith NTT R&D

2. WEB as Sensors

Transform WEB(without APIs) to

IoT Data Stream instantly

• Websites about city already exist a lot

• Some of them are periodically updated

• Act alike sensors

Change such websites to real IoT data stream

One billion websites

Lesson Learnt

• Only big companies / cities can lead smart city ?

– should be NOT !

• Possibility to

– leverage daily city service as sensing tasks

• “sharksucker” sensing with public cars

• City staffs acting as sensor

– generate massive IoT data stream without new IoT deployment

• Possibility to leverage any city information to enhance any existing services

– Open the data, then open community can leverage the data

– Open Smart City Ecosystem

SFCity Platform: Boot the Open Smart City

• For any cities without high cost

• Maximize utilization of existing city assets

• SFCity: open smart city platform

– Enables to change WEB to data stream

– Providing unified access to various data stream

– Available online: http://www.sfcity.jp

• Real deployment to Fujisawa city, Japan

– 100 garbage trucks has been sensorized

– 3,500 city staffs can act as sensors

– 10,000 Various WEBs has been sensorized

– Use for city management, reducing garbage, disaster management.
