20% of CO 2 emissions is from vehicles CO 2 emissions is to be reduced by 6% during 2008-2012 ITS is expected to be a strong weapon for environmental sustainability Carbon dioxide emissions in Japan Consumer (commercial) 16% Consumer (household) 13% Other 12% Industry 38% Transport 21%! (Vehicle: 90%of transport) 4)Others Projected reduction of CO 2 emissions Measures 1)Smooth traffic flow 2)Traffic demand management 3)Use of public transportation Reduce road works Develop traffic safety facilities Tele-working, etc. Eco-driving Anti-idling automobiles Projected emissions reduction (1000ton-CO2) 3600 (VICS : 2400) 300 3800 500 500 3400 1300 600 *)Projected reduction of CO 2 emissions in Kyoto Protocol Target Achievement Plan 2 ( Design CO2-saving transportation systems )
Various measures for each situation Kind of measures 1)Smooth traffic flow 2)Traffic Demand Management 3)Promote use of public transportation 4)Other measures Concrete measures in Japan - Eliminate traffic jam at tollgate by increasing ETC (Electronic Toll Collection) usage rate to 50%. - Improve access and reduce traffic jam on the roadside by smart interchange. (Under trial) - Wide and detailed information providing by advanced VICS. (Under research) - Environmental road pricing, fee measures, etc. - Highway bus location system contribute to the greater convenience in public transportation, and is utilized as probe data. - Evaluate economic loss due to traffic jams using probe data. - Eco-driving by monitoring fuel consumption and driving condition. 3

1) Smooth traffic flow (Smart Interchange) Smart interchanges, dedicated for ETC, will contribute to less congestion Average distance between interchanges Japan :About 10 km Europe and North America:4-5 km Field trial on 29 locations nationwide Kurosaki Yamato Sagae Arai Chojahara Obuse Nyuzen Johana Fukushima Matsukawa Ohsa Tokumitsu Nasukogen Yoshinogawa Amagozen Kamikawachi Kanagi Tomobe Kake Miyoshi Sue Komayose Sakudaira Futaba Fujikawa Obasute Enshu Toyoda Kibi Kamigo Kawashima Introduce smart interchanges 5
1) Smooth traffic flow (VICS) Started in April 1996 Provide real-time road traffic information on car-navigation system Schematic depiction of VICS Providing information using three communications and broadcasting media Prefectural police agencies Road traffic information Road administrators Japan Road Traffic Information Center Optical beacons VICS Center FM broadcast Radio beacons Text display (level 1) 2 kilometers of congestion ahead due to an accident between Gotemba and Susono. Simple diagrams (level 2) 75minutes 65minutes 75minutes Map display (level 3) 6
1) Smooth traffic flow (VICS) Wide and detailed information by VICS using 5.8GHz-DSRC [Wide range of information] [Information by voice] [Information by voice] Urayasu to Makuhari: 2 km congestion due to an accident Urayasu to Makuhari: 2 km congestion due to an accident Congestion 2km ahead 7

3) Promote use of public transportation Bus location information provided through internet Park and Ride system trial in many cities using IT Bus location systems Park and ride system P&R Approaching bus indicator at a bus stop P&R P&R Bus stop information accessed by cell phones 12
2. Platform supports a variety of measures An environment that supports multiple applications from a single on-board unit Promote the establishment of an open platform This highway information was announced at X:00. Traffic is congested for X kilometers between Y and Z. X Street is closed to traffic. There is a traffic accident X kilometers ahead. Please turn right in X meters There is a traffic accident X kilometers ahead. The distance to your destination is approximately X kilometers. You have five new e-mails. If a different device is needed for each application.. Multiple applications with a single ITS on-board unit 13
2. Platform supports a variety of measures From separate platforms to a common platform This platform will support a wide variety of applications Application Application Public applications Private applications Software OBU Software OBU Common software OBU for multi application Hardware Hardware Common hardware VICS ETC. First stage Open platform Second stage 14
2. Platform supports a variety of measures Common platform for sustainable society Awakening various measures and services toward environmental sustainability using a common platform ITS enter the second stage and common platform and new ITS service in 2007FY Private parking facilities Gas stations ITS services in 2007 Information provision along roadways Information connection at rest areas Public parking lot settlement Platform Restaurants Dispatch control Convenience stores and supermarkets Traffic control 15
