3. Introduction – Japan’s ITS
Safety & Sustainability are big issues
Disaster-prone & congestion-prone
Public sectors have taken the lead by Infra-based systems
Since 1970, road & traffic management has utilized large-scale data obtained by infra sensors
Provided also to travelers & drivers as traffic info
ETC started in 2001, covering nationwide toll roads
Active member of ISO/TC204 since its creation

4. Players in the National Gov.
Cabinet Office
Policy planning, Strategic budget allocation
National Police Agency
Traffic control, safety & regulations
Ministry of Internal Affairs & Coms
ICT strategies, Radio resources allocation
Ministry of Economy, Trade and Industry
Industries, Technologies & Standards
Ministry of Land, Infra, Transport & Tourism
Road construction & operation, Toll roads
Public transport, Vehicle homologation

6. Probe-based services By vehicle manufactures, since 2003
Honda, Toyota, Nissan, & NAVI operators
Using cellular coms, among member vehicles
Big data processed into value-added drivers’ info
Private data be integrated for public purposes
Disaster relief routes, Accident blackspots …
By MLIT, since 2011 (ETC 2.0)
Using DSRC (ETC+I2V info exchange) at 1600 spots in 2016 mainly on expressway network

7. Private data integration for Public
Utilizing probe vehicle traces finding ‘passable routes’ for disaster relief activities.
Kyushu quake first hit at 2126h 4/14/2016. ITS Japan responded by probe data integration.
Vehicle trace data contributed by Honda, Pioneer, Toyota, Nissan, Fujitsu, Isuzu, and UD trucks.
Passenger vehicle traces 4/ h-1100h
Heavy vehicle traces 4/ h-2400h

9. Safety & Sustainability in Aging JP
Road traffic accidents still persist
More than half of fatalities are elders
“Mobility” is emerging issues in Japan, esp. for aging society & increasing foreign visitors
PT e-payment integration may be a good practice
PT service level is acceptable in dense urban areas, not in suburb or rural areas
Car-sharing & Ride-sharing are less common
Autonomous vehicles are promising for elder transportation poors

10. E-payment integration
PT e-ticketing
87 M IC cards issued by 78 PT operators (2015)
Independently issued, but most of them are interoperable
PT fare + Purchases at retailers
One of the major e-payment media nationwide
Automatically topped-up by linking CC accounts
Japan Railways based Card
Non-Japan Railways based Card

11. Vehicle Safety Sells 1960s Car ownership boomed
1990s Driver protection & safety support devices accepted
Seat belts, Airbags, Side-impact protections
Anti-lock braking, high-mount stop-lamp
2010s Level 1 active safety options preferred
Adaptive cruise control, Automatic braking
2016- Level 2 vehicles on the market

12. For further advanced ITS
National Gov launched strategic initiatives
Policy for ITS/Automated driving Innovation
Strategic Innovation Promotion (SIP) Program
“Public-Private ITS Initiative/Roadmaps 2016”
Automated driving systems
R&Ds & demos, regulations & standards for deployments
Traffic big data platforms
Dynamic Maps, Traffic-related open data
Privacy and security issues
Social acceptance
