In Japan, the guideline for the bus crash test was worked out in 1999. Bus crash safety in the situation where seat belt wearing is not obligatory for bus passengers was investigated. Sled tests of which the test parameters were seat belt, seat interval, and posture were undertaken. For the first row passenger three point seat belt effectiveness and for other passengers two point seat belt effectiveness were studied. In this report, the test results were considered in relation to international harmonization, and current research activities are described. For the covering abstract see ITRD E825082.
