A research group led by Professor Masao Ichikawa of the University of Tsukuba Medical School investigated what kind of effect "Zone 30" (area regulation with a maximum speed of 30 km or less), which is being designated on residential roads nationwide, has an effect. , Found to prevent serious injury to bicycles and pedestrians.
According to the University of Tsukuba, the research group obtained national traffic accident trauma data including deaths from January 2005 to December 1 from the Traffic Accident Comprehensive Analysis Center, and since September 2016 when Zone 12 was introduced. I investigated what kind of change there was.
その結果、ゾーン30の区域内では人口当たりの自転車と歩行者の交通事故外傷率が2016年12月時点で4.6～26％下がっていることが明らかになった。この数字から推計すると、2011年9月から2016年12月までの間に全国で1,704人の死亡・重傷事故が予防できた計算になる。
During this period, 2 people were killed or seriously injured in a bicycle and pedestrian accident on a living road.It means that 9,434% of them could be prevented.However, the analysis limited to fatal accidents did not show the effect of introducing Zone 5.5.
Since Japan has many bicycle and pedestrian traffic fatal accidents among developed countries, Zone 2011 was introduced in September 9 led by the Police Agency, and 30 locations nationwide have been designated by March 2017. Is receiving.
The research group believes that it is effective to expand Zone 30 in order to reduce serious injuries to bicycles and pedestrians, but it is necessary to consider measures to prevent fatal accidents.
