Ji'nan traffic police laboratory: how much
police testing brake distance on mobile phones? A few days ago, Ji'nan traffic police Wang Xuanfei A traffic accident was sacrificed on the post, and the direct fuse of the accident was that the driver's call during the driving process affected driving. What's the harm of driving and playing WeChat? This morning, the traffic police in Ji'nan Tianqiao made an experiment on the site to test the impact of driving on a mobile phone.
according to the police of the Ji'nan Tianqiao traffic police team, the driver's attention is slowly stolen by the car. From the probability of a car accident, the probability of a traffic accident is 23%, which is 23 times the normal driving. In addition, the probability of cannabis traffic accidents accounted for 21% and drunk driving accounted for 12%, indicating that driving text messages is more dangerous than drunk driving and drug driving.
when the speed is at the speed of 60km/h, the lower head is 2 seconds, equivalent to about 33 meters blind, and at least 20 meters in the event of an emergency. It will take about 12 seconds to open and read a micro-blog with a smart phone, equivalent to a car blindness of about 200 meters.
does it really have such a huge impact on driving? To make it clear, this morning, the Ji'nan Tianqiao traffic police team conducted an experiment at a driving school in Ji'nan, respectively, at the same speed, focusing on the normal driving, driving by phone while driving, short hair short message. In the three cases of WeChat driving, the processing time was tested.
Experiment 1: the emergency brake driver's attention concentrates on the speed of driving the vehicle at 40 kilometers per hour after a normal driving. The driver suddenly appears an unidentified object at 50 meters ahead. The driver immediately takes an emergency brake after it is found, and the brake distance is 15 meters. The vehicle is successfully avoided. Unidentified objects.
experiment two: when a car is driven by a mobile phone, an emergency brake driver calls at the speed of 40 kilometers an hour and drives a vehicle at a speed of 40 kilometers an hour and suddenly appears an unknown object at 50 meters ahead. Immediately after the discovery, the driver took emergency braking measures, the braking distance was 27.7 meters, and the left front wheels rolled up unknown objects. The test showed that when the phone was on the phone, the reaction rate of the driver was almost twice as slow as that of the normal driver.
experiment three: when driving with a mobile phone to send information, an emergency brake driver has a low hair short message and a WeChat also drives a vehicle at a speed of 40 kilometers per hour and suddenly appears an unknown object at 50 meters ahead. Immediately after the discovery, the driver took emergency braking measures. The braking distance was 37.2 meters, and the vehicle directly hit the object and then rolled it.
Xu Ning, the police of the Tianqiao traffic police team, told reporters that because they were driving while they were calling, his brain was not all on the car, and the reaction slowed down in the discovery of unidentified objects. At the same time, because people's eyes, looking from a distance or from a distance, there will be some switching time, called adjustment. Under normal circumstances, the switching time may not have much impact, but when driving motor vehicles, this time difference is often fatal. Moreover, when the driver looks at his cell phone, he will ignore a lot of road information. Once an accident happens, the consequences will be disastrous. (Mafeng Mu Nan)
