5 VICS What s VICS? A groundbreaking telecommunications system that sends out real-time traffic congestion information and traffic control information, edited and processed in the VICS Center, through various communications mediums. The information is displayed in text and graphics on car navigation systems and other onboard units. VICS information is provided 24 hours a day throughout the year. Information collection Information processing Information provision Information utilization Road Administrator radio beacon (highway) 64kbps Car navigation, etc. Level I: Text Information JARTIC VICS Center optical beacon (main road) 1Mbps Level II: Simple Graphic Information Prefectural police department FM multiplex broadcasting (wide areas) 16kbps Level III: Mapped Information million Total Number of Shipped VICS System Equipment Total Number of All Shipped VICS July, million November, million Jun-96 Dec-96 Jun-97 Dec-97 Jun-98 Dec-98 Jun-99 Dec-99 Jun-00 Dec-00 Jun-01 Dec-01 Jun-02 Dec-02 Jun-03 Dec-03 Jun-04 Dec-04 Jun-05 Dec-05 Jun-06 Dec-06 Jun-07 Dec-07 Nov-07 Jun-08 4

9 Millimeter Wave Car Radar [Type of Sensor] Object Sensor Supersonic sensor Laser sensor Characteristics Small-scale and low cost, but, easy to receive surrounding noise. Short distance. High precision, high functionality possible. Weak against poor weather conditions (especially fog). 24GHz (Being discussed in the Telecommunications Council) 60GHz Enacted in Since GHz Most commonly used Since 1997 Millimeter radar High precision, high functionality. Can be used in all weather. Used both in short and long (1~100m) Additional bands (ex. 79GHz) (R&D to High Resolution Millimeter Rader System for ITS) Image sensor High precision, high functionality possible. Complex image processing technology required. Weak against bad weather (particularly fog and rain). Millimeter Wave Car Radar Millimeter wave Car on side Car in front ~100m 8

10 High Resolution Millimeter Rader System for ITS Outline Millimeter rader Close two objects 1Develop broadband radar using high spectrum band (79MHz band) It is difficult to identify objects preciously by current radar system (60/76GHz radar) because current millimeter radar uses wider pulse (uses MHz bandwidth) 2Investigate methods to avoid interference with millimeter radar systems itself Possibility of interference Schedule Current radar system Distance Broadband radar (1 1.3 GHz bandwidth (max 3GHz)) Rule making (3 year project) Realize high resolution and high accuracy Other system s ch To avoid interference, change spectrum band to use accordingly 78~81GHz f Distance New radar system Fail to identify the objects is one person Be available to identify two different objects Distance Target Current radar system 1 m resolution New radar system 20 cm resolution 9

11 Large-scale demonstration tests for Driving Safety Support Systems(1) -IT New Reform Strategy- Targets The world s safest road traffic environment - Reducing traffic fatalities to 5,000 or below - Reduce the number of traffic fatalities and serious injuries by deploying Cooperative Driving Safety Support Systems. Policies Based on the results of the above investigations, conduct large-scale verification testing of Driving Safety Support Systems through collaboration between the public and private sectors on the selected regional public roads while maintaining harmony with local traffic patterns, investigate the best form of effective service systems, and make quantitative assessments of the contribution to reductions in traffic accidents by FY

12 Large-scale demonstration tests for DSSS (2) ITS Promotion Council (ITS-Safety 2010) The New IT Reform Strategy stipulated that form a joint committee from the public and private sectors in early 2006 investigate the form of effective services/systems. In April 2006 the ITS Promotion Council and Working group was established with the Cabinet Secretariat (IT Policy Office) as the coordinator and its members are now examining large-scale demonstration tests. [Members] 4 ITS-related agencies/ministries (NPA, MIC, METI, MLIT), Cabinet Secretariat, Nippon Keidanren (Japan Business Federation), ITS Japan, Compiled The form of the demonstration tests for the Implementation of Driving Safety Support Systems report 3. Driving Safety Support System Platform Driving safety support systems can be categorized into the following three systems: (1) Road-to-vehicle communication systems (2) Vehicle-to-vehicle communication systems (3) Intercommunication systems between pedestrians, roads, and vehicles 11

13 The verification tests of DSSS by MIC Investigations and verifications for the practical use of driving safety support telecommunication systems ( [scheduled]) Overview: In actual environments, verify the effectiveness of a number of radio spectrum media in vehicle-to-vehicle communication systems and road-to-vehicle communication systems that support safe driving. Contribute to pre-testing in FY2007 and large-scale demonstration tests in FY2008 Case 1: Rear-end collisions Case 2: Collisions with oncoming vehicles 車車間通信により 接近車両の情報を入手 直交道路上を走行中の車両に対する情報提供 注意喚起 警報 制動制御 停止車 低速走行中の車両情報を送信 自車位置等の情報を送信 状況 : 追突場所 : 単路 交差点違反項目 : 安全運転義務違反 状況 : 出会い頭衝突場所 : 一時停止交差点 信号なし 一時停止なし交差点違反項目 : 安全運転義務違反 12
