  1. Informal Document No. GRSP-40-16 40th GRSP 12th- 15th December 2006 Agenda Item B.1.3. Survey on the Effectiveness of Safety Belt Reminder System Japan December 2006

  2. 1. Objectives In Japan, it has been mandatory since March 2005 to equip the driver’s seat of passenger cars with the safety belt reminder system (SBR) (mandatory for new-model vehicles since September 2005). • To confirm the effect, following survey has been conducted. • The rate of safety belt use with / without SBR • How and when SBR is activated • Positive and negative evaluations of its functions • Passenger seat SBR effect for future reference

  3. 2. Method of Survey The 6448 vehicles driver’s use/non-use of safety belt was visually checkedat parking lot entrances of “road station of arterial roads (speed limit 60 km/h)” and “shopping mall”. • Passenger cars were selected with / without SBR equipped. • 268 SBR-equipped vehicles users were interviewed.

  4. *: p<0.05 ** **: p<0.01 100 97.3 90.1 90 Rate of use (%) 80 70 With SBR Without SBR 3. The rate of safety belt use with / without SBR • 474 (7.4 %) vehicles were equipped with Driver SBR. • The Safety belt use with SBR vehicles were +7.2% (97.3% ← 90.1%) higher than without vehicles. Rate of Safety Belt Use with / without SBR +7.2%

How and when SBR is activated • Most of activate condition was in short term such as “delay of buckling-up” and “ Short distance”. • 65.3% trip time was with in 30 min. Trip Time Distribution Conditions of SBR Activation Trip Time (min.)

  6. 100 90 83.8 80 9.0 Turn down the volume 70 5.1 Shorten the alarm duration 60 3.9 Change to voice Rate (%) 50 2.0 Change the sound quality 40 1.2 Turn up the volume 30 1.2 Activate the alarm earlier 16.2 20 0.8 Change to melodic alarm, etc. 10 0.4 Elongate the duration 0 Useful Not useful 2.0 Other 74.6 No request 0 10 20 30 40 50 60 70 80 90 100 Rate (%) 5. Positive and negative evaluations of its functions • Approx. 84% of the users answered that the SBR audible warning was useful. • 74.6% users answered “No request” for SBR function.

Passenger seat SBR effect for future reference • 2443 (38%) vehicles had passenger occupants. 116 (4.7%) vehicles were equipped with passenger seat SBR. • The Safety belt use with SBR vehicle was +11.0% (95.7% ← 84.7%) higher than without vehicles. • 11.2 % was activated by “Luggage on the seat”. Conditions of Passenger's Seat SBR Activation Rate of Safety Belt Use by with / Without passenger’s seat SBR

  8. The rate of the driver’s safety belt use with SBR vehicles were +7.2 % higher than without vehicles. Therefore, SBR is very effective to increase the driver’s safety belt use. SBR was activated mostly in short term such as delay of buckling-up or short distance driving. Therefore, Short term deactivation could considerably reduce the effective. With regard to the reference investigation of passenger seat SBR, it was also effective, however, there was still a issue of caused by putting luggage and seating frequency. Therefore, further discussions for technical requirement and effectiveness study are necessary. 7. Summary
