Mention old freight car, a lot of people " talk about goods to change "
Main because of motor vehicle of pedestrian, blame even car and old freight car
The consequence that produces an accident is more serious
Turn in old freight car especially when
We view two accidents of near future happening first
This year on April 23 in the morning at 7 o'clock, road of experienced battalion of horse of city of Shanxi province Taiyuan He Yudong line crossroad, by the car of be involved in of mother and daughter that electric car drives a pair when an old freight car is turning, cause 2 people to die on the spot.
Van turns to use phone base of car of car be involved in
This year on April 20 18 when, roundabout of lukewarm Yang Lu and Wen Beilu manages Beijing Haidian division, when truck of a heavy-duty dump turns, with accident of a dynamoelectric bicycle and traffic of a bicycle happening, send two hurt to death.
When van turns, with report motor-car and bicycle produce collision
Two thing onetime capital are old freight car above in bend when those who happen, the happening that what reason caused an accident be after all?
Vigilant old freight car " inside annulus poor "
From inside accident video, can see above old freight car is in when the electric car in two accidents, bicycle and barge against of old freight car " inside annulus poor " area. So, what is " inside annulus poor " ?
Inside annulus difference is when showing car turns, inside of front-wheel drive turn radius and inside of rear wheel turn radius is absent same on orbit, front-wheel drive turns inside radius and inside rear wheel turns the difference of radius, those who say for inside annulus poor.
Inside annulus poor effect graph
Inside annulus graph of differential condition effect
If hang down to observe the condition when car turns continuously from altitude, with respect to meeting discovery, turn car has shift for fulcrum with inside rear wheel, the area that around wheel has delimited is different actually. Automobile body is chiefer, turn range is bigger, round of formation difference can jump over big. Say simply even if, the some object that front wheel of old freight car can bypass, and rear wheel does not circle the past however, and this one area is van drives of person line of sight on the right side of blind area, if as it happens of participator of other liaison man is in this one blind area inside, dangerous sex cans be imagined.
Perpendicular observation car turns condition
Inside annulus the blind area that difference forms
"Inside annulus poor " does the accident have much dreariness? Look in light of below these shocking pictures!
How to prevent old freight car inside annulus poor " have a person "
Be not motor vehicle and pedestrian
? When passing through on road, answer to maintain enough safe space with old freight car as far as possible. Be in especially alternate mouth, want special attention the old freight car of right-hand rotation, do not surmount the old freight car that turning first, do not let oneself be in old freight car " inside annulus poor " inside area, prevent to produce collision accident.
Old freight car drives person
? Seasonable decelerate answers before turning, all round much observation circumstance. Must go slow carefully, do not grab row, maintain low speed, observe the condition all round automobile body more, ensure to advance again without critical factor all round automobile body, this kind of accident can prevent on certain level.
? Big turn turns as far as possible when turning, maintain certain safety to be apart from with footpath, Lu Yuanshi.
? Add outfit blind area to photograph lens of convex perhaps like the head roundlet, reduce visual blind area, notice observation more in travel process.
? Once appear accident, seasonable brake.
