3 1. Introduction - Electronic Toll Collection System (ETC) Approx. 30 million ETC on-board units have been shipped (as of May 2010). The nationwide utilization rate: 84.6% (as of May 2010). Trends in the use of ETC Number of vehicles using ETC (10,000 vehicles/day) Utilization rate Apr 30 May 6, 2010 About 7.31 million vehicles/day Utilization rate: 84.6% December 2001 About 0.50 million vehicles/day Utilization rate: 0.9%

5 1. Introduction - Vehicle Information Communication System (VICS) Provide real-time road traffic congestion information on car navigation system which started in 1996 Example of Display Simple diagrams Map Display 4

6 1. Introduction - Vehicle Information Communication System (VICS) Over 26 million VICS-OBUs have been shipped (as of ) 30,000,000 26,786,500 25,000,000 23,813,302 21,193,341 20,000,000 18,172,686 15,000,000 15,017,556 11,885,577 10,000,000 9,117,108 6,580,912 5,000, ,815,431 2,804, , ,4921,019,659 4,488,

7 2. Development of Smartway -Definition Definition of Smartway a road system which can exchange various types of information among cars, drivers, pedestrians, and other roadway users. Roads Communication Smartway Vehicle 6

8 2. Development of Smartway New platform - A single ITS on-board unit (OBU) will provide various services according to establishment of common platform 1995 Car na avigation VICS 2.4 GHz Beacon Information provision 2001 ETC 5.8 GHz DSRC 2007 Diverse media Car navigation Single ITS-OBU 5.8GHz DSRC Two-way communication Large-volume communication Providing information on assisting safe driving Vehicles merging from the left. Drive carefully! Providing information on conditions ahead 1 km ahead. Gaien Wide range traffic congestion information Parking lot payment :Service :On-board unit

9 2. Development of Smartway history Public - Private Joint Research (NILIM, 23 companies) Smartway Demo 2006, Standardization 2007 FOT, Smartway Demo 2007 (Metropolitan Expressway) 2008 FOT (in the three large metropolitan regions) 2009~ Practical service deployment 8

10 3. Field Operational Tests(FOT) Providing Information on Obstacles Ahead - FOT were conducted at three major metropolitan regions and other regions in FY [Osaka/Kyoto] - Providing Information on Conditions Ahead (by audio) Niigata [Osaka] - Warning a driver against overshooting at sharp curve ahead - Providing Information on Obstacles Ahead - Merging Assistance Nagoya [Hiroshima] - Warning a driver of excessive speed operations Hiroshima Osaka/Kyoto [Niigata] - Vehicle behavior data collection (Road surface snow accumulation information) Tokyo [Tokyo] - Providing Information on Obstacles Ahead / Conditions Ahead - Providing Information on Road Traffic Conditions (by still images) [Nagoya] - Providing Information on Obstacles ahead / Conditions Ahead - Warning a driver of hazard along curve ahead 9

11 3. Field Operational Tests(FOT) Providing Information on Obstacles Ahead Outline of FOT at Rinkai Fukutoshin Exit of MEX Stopping car ahead. Drive carefully! Stopping car ahead. Drive carefully! sensor Up hill 10

12 3. Field Operational Tests(FOT) Providing Information on Obstacles Ahead Stopping car ahead. Drive carefully! Intersection ahead. intersection & signal Stopping cars No stopping cars ordinary road blind spot for drivers DSRC Provision of information Metropolitan Expressway 11

13 3. Field Operational Tests(FOT) Providing Information on Obstacles Ahead Cumulative distribut tion of relative frequency 100% 80% 60% 40% 20% 0% 98.0% 100.0% 89.0% 92.5% 100.0% 77.5% 74.0% 49.0% 53.8% 33.8% 21.0% 7.0% 12.5% Navigation with service system N = 100 linked N = % No without service service N = 80 N = 80 0~50 50~55 55~60 60~65 65~70 70~75 75~80 80~85 85~90 90~95 95~100 Speed at speed SEP (km/h) evaluation locations (km/h) SEP: speed evaluation point : driver can see stopping vehicles ahead right before 12

14 3. Field Operational Tests(FOT) Providing Information on Obstacles Ahead It is good because I knew in advance が that a car was stopped or that there was an intersection and prepared mentally. It is good because I had leeway to 良 avoid a rear-end collision and emergency braking. It is good because it has a good た impact on more cars. 13% 50% 87% It is good if the service is provided た during rainfall or at night. 30% It is unnecessary because drivers た travel slowly on the rising grade. It is unnecessary because I always 要 drive carefully. 0% 3% N=30 (multiple answers permitted) Others 他 0% 0% 20% 40% 60% 80% 100% 13

15 4. Summary ETC and VICS have been on operational stage and utilized nationwide. The second generation ITS service, Smartway, has been developed based on ETC and VICS technologies through a lot of FOTs. It has been confirmed through FOTs that Smartway works effectively and accurately.
