The moving potential difference between images can measure the current speed.
Witnesses at the scene, including the internet, said that BMW was extremely fast at that time, with a speed of 200 kilometers per hour. Some people also question this and think that this speed can't be achieved in urban areas. Although the police have not announced the specific speed, there is no doubt about speeding.
"It is not feasible to rely solely on the damage degree of the vehicle and the driving computer that comes with the vehicle." A person familiar with the matter told the reporter that through the nearby surveillance video, two points of the BMW can be locked and found, and then the speed at that time can be calculated through the moving position difference between the images. No drug driving, no drunk driving, why did he drive so fast?
I'm trying to ask, but it's difficult for the driver to communicate.
Earlier, it was reported that ice was found on the BMW, and the driver was suspected of driving under the influence of drugs. However, the second circular issued by Nanjing traffic police clarified that no drugs were found at the scene of the accident, and at the same time, after investigation and identification, Wang was ruled out for drunk driving and drug driving. As a result, the focus problem appeared. No drug driving, no drunk driving. Why did he run a red light at the speed limit?
People familiar with the matter said that the investigators asked overnight, but the driver was uncooperative, mentally unstable and difficult to communicate, including the urine test in the hospital, which was completed under very difficult circumstances. Whether it is an emergency or a problem, it is a core of this accident to let the driver run the red light at a speed limit. The whole inquiry work is centered around this and will not be released until it is officially confirmed. Will this driver be the "top bag"
The police confirmed the man through DNA identification.
From the news that the driver was suspected of drunk driving to the police's final rumor that it was not drunk driving, this also made some citizens question whether the driver was a "top bag".
"It must have locked the driver. This is the relevant notification." One person said that there are many probes on the road, and they are high-definition probes. From the time the driver left the decoration city, including the road sections along the way, until the last accident, there were enough monitoring pictures to prove that this person was the perpetrator.
"However, fully confirming the true meaning of this perpetrator is through DNA identification." Informed sources said. Do you have a driver's license or not Are there any drugs in the car?
With a driver's license, "ice" is actually corn flour.
"There is nothing to say about the driver's license, and the ID card is easy to check." People familiar with the matter said that the driver Wang had a driver's license and it was within the validity period.
Regarding the discovery of ice poison at the scene, the person said that powdery items were indeed found at the scene, but after identification, it was not drugs, but corn flour.
In fact, in the second briefing issued by Nanjing traffic police yesterday morning, there was a corresponding explanation on whether drugs were found. Why can the seized car still be on the road?
Seizure doesn't mean you can't go on the road.
"Being sealed is not what we thought. Put a seal on an item and then you can't move. " A person familiar with the matter said that the Regulations on Motor Vehicle Registration stipulates that motor vehicles seized by people's courts, people's procuratorates, public security organs or other administrative law enforcement departments shall not be registered, mortgaged or pledged.
According to reports, laws and regulations related to road traffic safety do not stipulate that vehicles detained by the court are not allowed to drive on the road. Therefore, vehicles in a sealed state can go on the road. It is true that the perpetrators are "bound" by wearing helmets.
At that time, my emotions were out of control, I hurt myself, and I beat and scolded the police.
After seeing the photos of Wang being controlled and wearing a helmet at the police station, friends and colleagues familiar with the decoration city repeatedly said that from the perspective of clothes and body shape, it should be Wang himself.
In the Decoration City, the reporter showed this photo, which was widely circulated on the Internet, to many businesses. A businessman who saw Wang that day said that from the clothes, it was indeed Wang himself. Many people who are familiar with Wang say that height 170cm is relatively thin. Although he wears a helmet, he obviously feels like him. "Why are you tied by the police and wearing a helmet? Afraid of his suicide? " These businesses asked.
When the reporter interviewed at Guanghua Road Police Station the afternoon before yesterday, a police official said that after receiving the police, they found a man with blood on his face, which was later confirmed to be the BMW driver Wang. According to reports, Wang was emotional at that time and did not cooperate with the police investigation. After being forcibly taken back to the police station by the police, he not only insulted the police, but also punched and kicked the police and even had a tendency to self-harm. In desperation, the police took restraint measures against him. He was very emotional, with blood on his body and torn clothes, and he was very uncooperative in insulting the police.
The police then forcibly brought the man back to the police station, but he was still very uncooperative. The police had to put a helmet on him and control his hands and feet. It is said that Wang was also taken to the hospital for a physical examination, which proved that there was no problem and his spirit was temporarily normal, and then he was taken back to the police station. At the same time, the police handling the case inquired on the public security police platform and found no previous record of Wang. According to the materials related to the speed appraisal of BMW passing through the intersection, the appraisal department mainly appraises the speed through surveillance video, copy of accident scene map, scene photos, etc. Among them, monitoring video includes intersection monitoring video and video taken by a small ordinary bus driving recorder.
The method to determine the speed of the accident vehicle is to measure the speed by video. That is, the number of image frames used can be calculated by monitoring the video frame rate and the distance the vehicle moves in each frame of the video. , finally figured it out. In the appraisal book, the appraisal opinion shows that the speed of Shaanxi AH8N88 small car passing through the reference line in the monitoring video picture is195.2 km/h. ..
So, what is the concept of driving on the road at the speed of 195.2km/h? Anyone who has driven an expressway knows that under normal circumstances, the expressway speed limit for small cars is120km/h/h.
It is reported that the running speed of the general motor train is 150-200 km/h, in other words, the speed of BMW passing through the accident intersection has exceeded the speed of the motor train (average). Nanjing police detained Wang on suspicion of traffic accident and reported it to the Qinhuai District People's Procuratorate of Nanjing for approval. According to Article 133 of the Criminal Law, there are three different degrees of punishment for traffic accidents: those who commit traffic accidents shall be sentenced to fixed-term imprisonment of not more than three years or criminal detention; Whoever escapes after a traffic accident or has other bad circumstances shall be sentenced to fixed-term imprisonment of not less than three years but not more than seven years; Whoever escapes and causes death shall be sentenced to fixed-term imprisonment of not less than seven years.
The police have determined that Wang's behavior has constituted abandoning the car and escaping after the incident. However, according to the lawyer, even if Wang's behavior constitutes a hit-and-run traffic accident, because two people in the car died on the spot, it does not belong to the rule of escape causing death. Therefore, according to the accusation of Nanjing police in criminal detention, even if Wang bears full responsibility for the accident and has the plot of escaping after the accident, according to the criminal law, his legal criminal responsibility is only three to seven years in prison.
However, some legal persons believe that the driver of BMW accident car should be convicted and sentenced for the crime of endangering public safety by dangerous means.
Because Wang drives a BMW at a speed as high as 195.2km/h and travels at such a high speed in the main urban area, it can be concluded that he had an indirect intention in the accident, which seriously endangered the safety of most people on the road. If the prosecution convicts and sentences Wang for this crime, he is likely to face a penalty of more than 10 years, even life imprisonment or death penalty.
