  1. Informal document No. GRRF-62-21 (62nd GRRF, 25-28 September 2007, agenda item 10(c)) The Promotion of Active Safety Measures in Japan - collision damage mitigation brake - September2007 Road Transport Bureau MLIT Japan

  2. Safety Policy of Government of Japan 120 100 80 60 40 20 2010 Target of safety measuresGovernment of Japan Number of injuries (Unit: 10,000 persons) Number of accidents (Unit: 10,000 accidents) Number of traffic accidents/injuries/vehicles (x10,000) Number of fatalities (Persons) 6,352(2006) Number of fatalities Ultimately Zero Number of vehicles (Unit: 1 million vehicles) 5,500(2010) 2006 [Based on Traffic Accident Occurrence Conditions (National Police Agency Traffic Bureau)]

  3. “The 2006 MLIT Transport Policy Council’s Report on vehicle safety ” 0 initial target in 1999 - 500 1,200 reduction - 1,000 Additional + 800 in 2006 - 1,500 Already achieved 1,000 reduction Reduction of fatalities since1999 （Ｉ） New target:2,000 reduction - 2,000 - 2,500 - 3,000 2003 1999 2005 2010 2015 Target of Fatality Reduction Effectby vehicle safety measures （ＩＩ） Continuous reduction after 2010 by active safety

  4. “The 2006 MLIT Transport Policy Council’s Report on vehicle safety ” Strategies for active safety measures • Short term measures: incentives for priority technologies should be considered. • Middle term measures : introduction of new type of accident analysis using driving recorder. • Future measures: development of communication technologies is important. After success of passive safety measures, prompt action should be taken now to expand utilization of active safety for continuous reduction after 2010 .

  5. Market introduction of Active Safety Technology • Technical measures • Technical guidelines based on “ the concept of driver assistance.” • Public outreach • Publication • Events • Knowledge for users • Basic information about ASV technologies • Industries’ effort • Motor vehicle industries • Truck operators • Government support • Clear message of importance of ASVs • Incentive measures

  6. Incentives • Heavy duty vehicles equipped with collision damage mitigation brake (CDMB) are subsidized from April 2007. Why collision damage mitigation brake on heavy duty vehicle was selected for incentives? • Matured technologies • Effectiveness • Social necessity ●When the vehicle approachs to former vehicle; The milimeter wave sensor is scannning former condition Pipipi! When Driver seems not to aware the former vehicle, warning activates Brake vtivate When the vehicle presumes to crash to former car, the vehicle activate the brake

  7. The estimated reduction volume by the vehicle speed • MLIT estimates that the number of fatal accidents related heavy duty vehicle can be reduced about 90% when collision mitigation braking system on the heavy duty vehicles reduce speed around 20 km/h. Total 86% reduction 87.5% 73.2% 97.7% 100% 79.6% 100% 100% km/h Number of fatalaccident Estimated Reduction volume ofthe number of fatal accident Matured Technology • It depends on the manufacture’s philosophy. Ex) Heavy duty vehicle equipped with the brake become to be sold. Effectiveness Social Necessity • More than 55% of accidents are rear end collisionDamage to other vehicles is 12 times more severe than collision with a passenger vehicle

  8. Technical regulation Technical guidelines for CDMB • For goods vehicles with a gross vehicle weight of at least 8 tons or a maximum loading capacity of 5 tons or more and … • ・When a forward obstacle has been detected and the predicted collision time falls below the collision judgment line (ex, 0.8sec), brake control function exceeding 3.3m/s2 shall be started. • ・When a forward obstacle has been detected and the predicted collision time falls below the collision risk judgment line (ex, 1.6sec), brake control function may be started. • ・ ・・・ At present, MLIT is discussing a technical regulation of collision damage mitigation brake equipped with these heavy duty vehicles.

  9. Conclusion • Transport Policy Council, which is advisory group of MLIT, revised the target of road safety in June 2006. • Continuous fatality reduction after 2010 is one of the new target. • To archive the new target, the promotion of the active safety technology is necessary. • Accordingly, to promote the active safety technology, MLIT started to give new subsidy for “collision damage mitigation brake” from April 2007. • At present, MLIT is discussing a technical regulation of collision damage mitigation brake for heavy duty vehicles.
