How dangerous is it to drive and check your mobile phone?

Some studies have pointed out that the response time of texting while driving will be twice as long as that of slow three, which is as dangerous as drunk driving! Whether it's true or not, just try.

Dashi-Xiaobai Xiao Yong, who just got his driver's license-an old driver with ten years' driving experience, suddenly appeared obstacles on the road. How did the two react?

The length, width and height of the obstacle are all 0. 1 meter, which is about the size of a chalk box. Wang Junhua, Ph.D., School of Transportation Engineering, Tongji University, said that the design of sight distance in road specifications was cancelled, and the size of obstacles was determined to be 0.1.1meter. Such a cube, as long as it is anywhere on the road, can definitely stop in front of this obstacle if it is driven at a prescribed speed. In order to make this obstacle move, we installed it on a remote control car. The experimenter will drive the vehicle at a speed of 50 kilometers per hour without knowing it. When the vehicle approaches, the remote control vehicle will suddenly rush out and block in front of the vehicle. Under the condition of normal driving, both cars are parked in front of obstacles smoothly, and the experimenter can do it without being surprised. Xiao Yong and Dashi were distracted by their mobile phones while driving, and failed to find the obstacles that suddenly appeared in front of them in time.

In addition, the history of novice drivers driving with one hand is even more hectic.

After many experiments and calculations, the time for them to find obstacles and take measures is 2~3 seconds slower than when they don't play with their mobile phones. According to the speed of 50 kilometers per hour, the distance that the car passes in one second is close to 13.9 meters. The distance the driver leaves when distracted, plus the necessary distance to brake, can only stop after driving for 30~40 meters. At this time, a car accident is inevitable.

Next, let's compare the driving state of watching mobile phones and drunk driving. In order to make the experiment safer and more scientific, we used the driving simulator of Tongji University in Shanghai to carry out the experiment. The test road is set as winding Panshan Highway. In order to increase the difficulty of the experiment, we also placed isolation piers at the corner. Let's take a look at the situation of playing mobile phone and driving first.

Mahayana, there are three problems in playing mobile phone while driving. 1. It is more difficult to operate the steering wheel with one hand:

2. Hit an obstacle three times and cross the line many times;

3. Seriously distracted, according to the instrument observation, 3 minutes of driving, the distraction time is as long as 36 seconds.

The situation in Xiao Yong is not good either. 1. Frequent braking, obvious shaking from side to side.

2. Hit obstacles 1 time

3. even: . . . . Fell off a cliff.

After instrument testing, Dashi and Xiao Yong spend 27% of their time looking at their mobile phones while driving.

In addition, when driving normally, the reaction speed is 0.6 1 s, while when driving with a mobile phone, the reaction time is 2.32 seconds, which is 3.8 times longer. This is enough to cause a traffic accident.

Xu Jungang, instructor of Caihe Squadron, Jianggan Traffic Police Brigade, Traffic Police Detachment of Hangzhou Public Security Bureau, said that anyone who makes or receives a hand-held phone while driving will be fined up to 200 yuan, and 2 points will be deducted. Using wechat and reading short messages are all hand-held ways to use the phone, and you must be fined. Next, we will test drunk driving. Dashi and Xiaoyong both finished a bottle of two 62-degree Erguotou. After resting for an hour, the alcohol tester showed that the remaining alcohol content in the two people was 137 mg/100 ml, which was a drunken state. It is said that wine makes people afraid, and the speed of Dashi has obviously improved a lot. However, 1. The car stopped suddenly and shook badly from side to side.

Drive off the road twice.

3. Too close to the opposite vehicle for many times, resulting in scraping.

As for Xiao Yong, alcohol also affects old drivers. 1. The steering wheel is unstable.

Drive off the road once.

This drunk driving, Dashi left the road twice, and Xiao Yong 1 time left the road; Their average speed increased by14%; The speed changes sharply, and the phenomenon of emergency stop increases; Unstable operation of the steering wheel causes obvious lateral shaking of the vehicle; Their reaction time increased by 1.3 1 sec.
