Question:
acceleration of death in traffic safety is how going on?
Answer:
traffic deaths accelerated from April 26 to protect the national road safety seminar reports: Chinas unusually severe road safety situation, the death toll was the trend of accelerated growth. Since 2001, for 3 years the number of deaths in traffic accidents more than 100,000 people, with an average of 300 people died per day, equivalent to an airliner crash.
accelerate the issue of traffic deaths is a more complex and comprehensive treatment of the issue of the need. Main reasons: First, the overly rapid growth of vehicles; Second, a new number of new factors; Third, there is a gap between the traffic control science; four is poor awareness of road safety.
govern: 1, road to ensure public security forces should be strengthened; 2, to enhance the safety of the driver training; 3, start-wide emphasis on community safety; 3, from the start to enhance children 5, strengthen the road construction and maintenance of facilities.
Answer:
acceleration of death
Western traffic management sector in order to traffic safety, the death of Special formulated 500g acceleration this value to Xingshi people. Acceleration means that if traffic exceeds this value, there will be life-threatening, then a large acceleration, the vehicle under normal circumstances is not, but if there is a traffic accident, will reach this value, because the collision time by vehicles short, most of milliseconds.
For example, two motorcycles per hour speed of 20km (5.6m / s), opposite the line of collision, the collision time in milliseconds level, then in such a short period of time, resulting in the acceleration a = V / t = 5.6 / 0.001 = 560g, it can be seen that the collision can produce such a large acceleration.

问题:
交通安全中的死亡加速度是怎么回事？
回答:
交通死亡加速，4月26日从全国公路安全保障座谈会的报道：中国道路安全形势异常严峻，死亡人数呈加速增长趋势。2001年以来，连续3年交通事故中的死亡人数超过10万人，平均每天死亡300人，相当于一架民航客机失事。
交通死亡加速的问题，是一个比较复杂且需要综合整治的问题。主要原因：一是，车辆增长过快；二是，新人新车因素增多；三是，交通科学管制有差距；四是，交通安全意识淡薄。
进行治理：1、公路公安应加强保证力量；2、加强驾驶员的安全培训；3、启动全社会gz重视交通安全；3、从儿童抓起增强交通安全意识；4、严厉惩罚违章驾驶行为；5、加强公路设施的建设和维护。

死亡加速度
西方交通管理部门为了交通安全，特制定了死亡加速度500g这一数值，以醒世人．意思是如果行车加速度超过此值，将有生命危险，那么大的加速度，一般情况下车辆是达不到的，但如果发生交通事故时，将会达到这一数值，因为，一般车辆碰撞的时间短，大多为毫秒级．
例如，两辆摩托车时速每小时20km（5.6m/s），相向而行发生碰撞，碰撞时间毫秒级，那么在这样短的时间内，产生的加速度为a＝V/t=5.6/0.001＝560g，可见在碰撞中能产生这么大的加速度．
