Study on new regulation concerning
Driver’s field of vision
Ministry of Land, Infrastructure and Transport
81th GRSG, October 9-12, 2001, Geneva
Contents
1. Background
2. Accident data
3. Blind spot on car
4. Existent national regulations concerning “Driver’s field of vision”
5. New regulation concerning field of vision
6. Estimation on the Accident decrease effected by improvement of visibility
BackgroundAccidents that seem to be caused by the blind spot
of driver’s field of vision have increased in number.Example; 1. Accidents that young children are sacrificed when the vehicle is
started 2. Accidents caused by remodeled MPV which remodeled to raise
height
“New regulation concerning driver’s field of vision”is expected.
Accident data
*Death in ‘96 – ’98 by traffic accidents occurred in immediate forward and left of vehicles when the vehicle is started

Blind spot makes young children to go out of driver’s field of vision
Blind Spot on MPV (1)
The Influence of raising heights of vehicles on driver’s field of vision
2.4m4.8m
Blind spot is enlarged when vehicle height is raised.

Blind Spot on MPV (2)
Existent regulation concerning driver’s field of vision (1)
The rear view mirror shall enable the driver in seating position to recognize at least part of a 30 cm diameter round column having a height of 1 meter which is placed in the area shown in the figure.
3) For “cab over” type Truck
(GVW is more than 8t) etc.

New draft regulation concerningdriver’s field of vision
Vehicle structure shall enable the driver in seating positionto recognize at least part of a 30 cm diameter round column having a height of 1 meter which is placed in the area shown in the figure.
This requirement may be complied by driver’s direct vision, or indirect vision made by rear view mirror or other devices. New draft field of vision

The object of driver’s recognition is specified here on the assumption that five-years old would be the lowest age with possibility to go out on road alone, based on sociologic analysis.

Calculated effect on preventing accidents occurred in the immediately near front or near left-side of MPV
*The figure is on the assumption that, 1) After the application of the new regulation, the MPV accident would occur in the same ratio as the other passenger car accident. 2) Even after the application of the new regulation, the accident involving persons elder than 13 years old would occur in the same ratio as the present accident, because they could be recognized by direct vision.
