'你不是开得太快，是'飞'得太低。'这一小品台词诙谐夸张，但却发人深省。11月8日，现实版的'飞车'表演就在西宁市惊心上演。当日17时10分许，驾驶人雷某某驾驶青B·05170号东风货车沿昆仑大道西段由东向西行驶至刘家寨村东口时，由于超速加之雷某某不注意观察前方事物，造成与由北向南横过道路的行人严某某相撞，致使严某某受伤，经送医院抢救无效于当日死亡。
'You are not driving too fast, it is 'flying' too low. 'This essay line is witty and exaggerated, but it is thought-provoking. On November 8th, the reality version of the 'Speeding' performance was staged in Xining City. At 17:10 on the same day, the driver Lei Moumou driving the Qing B.05170 Dongfeng truck along the western section of Kunlun Avenue from east to west to the east exit of Liujiazhai Village, due to the speeding plus Lei Moumou did not pay attention to observe the things ahead It caused a collision with the pedestrian Yan Moumou who crossed the road from north to south, causing Yan Moumou to be injured. He was sent to the hospital for rescue and died on the same day.
超速行驶对行车安全为什么构成这么大的威胁？超速行驶主要有以下危害：一是超速行驶，视力下降，判断不准。驾驶人在行车中的视力称为动视力。一般来说，动视力比静视力低10%至20%。动视力与速度成反比，车速越快，视力下降越多。当时速为60公里时，视认距离为240米，而80公里时，视认距离减少到160米；车速越快，视野越窄，这就是所谓的'隧道型视野'。当时速为40公里时，视野为100度，时速为100公里时，视野仅为40度，这时两边的景物无法看清；二是超速行驶，反应距离延长。当时速为60公里时，人的反应距离为16.7米，当时速达100公里时，反应距离为27.8米。车速越快，反应距离越长，危险越大；三是超速行驶，制动距离延长。不同的路面，摩擦系数不同，车速越快，制动距离越长，发生事故的可能性陡增；四是超速行驶，干扰正常车流。超速行驶的车辆必然时刻处于超越正常行驶车辆的状态，每次超车无论是变道还是驶回原车道，都会形成交织点，而每个交织点就是一个交通事故隐患；五是超速行驶，加重事故后果。车速越快，动能越大，冲击力越大，发生事故碰撞时后果越严重。数据显示，当汽车时速20公里，把人撞死的几率为10%，40公里时超过30%，60公里时超过90%，80公里以上时则达到100%。由此可见，超速行驶是危险可怕的，'超速行驶'历来是公安交管部门整治的重点交通违法行为。
Why does speeding pose such a big threat to driving safety? Speeding mainly has the following hazards: First, speeding, vision loss, and judgment is not allowed. The driver's vision in driving is called dynamic vision. In general, dynamic vision is 10% to 20% lower than static vision. Dynamic vision is inversely proportional to speed. The faster the speed, the more vision loss. At a speed of 60 kilometers, the visual distance was 240 meters, and at 80 kilometers, the visual distance was reduced to 160 meters. The faster the speed, the narrower the field of view, this is the so-called 'tunnel vision'. At a speed of 40 kilometers, the field of view was 100 degrees. When the speed was 100 kilometers, the field of view was only 40 degrees. At this time, the scenery on both sides could not be seen clearly. The second was speeding and the reaction distance was extended. At a speed of 60 kilometers, the reaction distance of people was 16.7 meters. When the speed reached 100 kilometers, the reaction distance was 27.8 meters. The faster the speed, the longer the reaction distance, the greater the danger; the third is speeding and the braking distance is extended. Different road surfaces have different friction coefficients. The faster the vehicle speed is, the longer the braking distance is, the possibility of accidents increases sharply. The fourth is speeding, which interferes with normal traffic. Speeding vehicles must always be in a state of surpassing normal driving vehicles. Each time an overtaking is changed or returned to the original lane, an interlacing point will be formed, and each interlacing point is a traffic accident hazard; the fifth is speeding and aggravating the accident. as a result of. The faster the speed, the greater the kinetic energy, the greater the impact force, and the more serious the consequences of an accident collision. The data shows that when the car has a speed of 20 kilometers per hour, the probability of killing people is 10%, when it is 40 kilometers, it is more than 30%, when it is 60 kilometers, it is more than 90%, and when it is 80 kilometers or more, it is 100%. It can be seen that speeding is dangerous and terrible. 'Speeding' has always been a key traffic violation in the rectification of the public security traffic control department.
虽然现在的道路限速系统应用的范围已经很广泛了，交通部门对超速者的处罚力度也在不断增加，但限速标志和处罚力度，只能让驾驶员被动的知道路段对应的限速，但还是有有很多驾驶者因为疏忽限速标致或者抱着侥幸的心里而超速行驶，带来很多安全隐患，而且由于路况多变，同段路在不同时段限速也可能不同，稍不注意，很容易引起交通事故。
Although the scope of the current road speed limit system has been extensive, the traffic department's penalties for speeding people are also increasing, but the speed limit sign and punishment can only let the driver passively know the speed limit corresponding to the road segment. However, there are still many drivers who are speeding because of negligent speed limit or holding their luck, which brings many safety hazards. Because of the changing road conditions, the speed limit of the same road may be different at different times. It is easy to cause a traffic accident.
综上，需要针对路况限速情况多变，限速标志容易漏看的情况，提供一种通过预设车辆行驶道路匹配的限速，当车辆行驶在道路上时，根据道路限速设置车辆极速，帮助驾驶员调整车辆极速，避免超速，增加行车安全性。
In summary, it is necessary to adjust the speed limit of the road condition, and the speed limit flag is easy to miss. Provide a speed limit that matches the road traveled by the preset vehicle. When the vehicle is driving on the road, set the speed of the vehicle according to the speed limit of the road. To help drivers adjust the speed of the vehicle, avoid overspeed and increase driving safety.
