One of aspect: why child usually can wait for one at a slow speed traveling automobile pass through; select to move on and sail the automobile that comes fast to one? that is because they are difficult to distinguish a motion or static automobile, also is confused about automobile and is out to such an extent that still be out slowly soon.There is individual this reason of cartoon special explanation in the U.S.: a child goes across the road, and goes to half, and a big lion runs far away, and the hair of lion, body constantly change at the volley, and it is to come to oneself that child tells lion at once, loses no time to run away; Change two automobiles into and open over to child, one fast one the appearance in automobile front does not change all the time slowly, though child has seen that being difficult to judge automobile is moving, opens unhappyly soon.
Two of aspect: less child's optic nerve does not also have zoon, and their visual field has only an adult's 1/3rd, and when their jaywalk, they can't see the thing beyond the limit, canthus, often note less than an automobile that is approaching.
Three of aspect: child thinks that the driver can see oneself.Many drivers run into going across the road upward spring suddenly and there emerged a the scene that child comes, and work as inquiry: " you do not see automobile? " child tends to tell me and has seen.Why seen that danger also rushes always forward? this be because: opening to oneself though child can notice automobile, but they can think own visible automobile usually mistakenly, the driver also one sees them surely, but also can think mistakenly that automobile can promptly stop as the pedestrian.
Four of aspect: when the people keeps to the right, also keep to the right with his unidirectional vehicle.The pedestrian sees that the car that head-on comes is from oneself left side far away, is difficult for constituting a threat to.On the contrary, with his equidirectional back vehicle, the pedestrian can't see, so these vehicles are very big to pedestrian's threat.
Interrelated data shows that the traffic safety accident that about 80% minor is taken place occurs in the way of going to school and leaving school.Therefore, how to improve that child's traffic safety is a problem that expectation solves in the way of going to school and leaving school.
