According to official reports, as of 2 p.m. on May 2, the Meida Expressway collapse accident has killed 48 people and injured 30 people, and 23 collapsed cars have been dug up.
While mourning the victims and caring for the injured, I also have an immature question I would like to raise for your attention:
In this landslide accident, how many cars were buried in it?
A brief recap of the changes in the data for downset vehicles:
The accident occurred in the early hours of May 1, and by the morning of May 1, the first wave of media reports said that 18 vehicles had fallen, and only one person was confirmed dead.
By the afternoon of May 1, there was new progress in the rescue, and more sad facts gradually appeared in front of people's eyes, the number of victims continued to increase, and the number of sunken vehicles became 20.
By May 2, the rescue had been almost completed, and the local government held a press conference to report on the accident, and the number of victims was fixed at 48, and the number of sunken vehicles had increased to 23.
It is easy to understand that the number of victims has gradually increased with the progress of rescue, and the people in the accident vehicle and the people under the earthwork must always be "rescued" to determine life and death. However, the number of wrecked vehicles has changed again and again, which is actually very puzzling and undesirable.
The accident occurred on the highway, which is a relatively closed section, and the number of vehicles in and out of the toll booths at both ends of the road is accurate statistics and can be accurate to the license plate.
In other words, it should be easy for the traffic management department to get accurate data on which vehicles entered this range on the night of April 30 and did not come out again until noon on May 1. One day's time is enough to call up all the "unaccounted for" vehicle information to verify by phone one by one.
How did you get to the real accident rescue site, or dig out one and count one manually?
Speaking of which, this issue is actually very important, and even human lives are at stake. If there is an accurate vehicle data at the same time as the rescue and excavation, the rescuers can do a good idea, and the number of cars dug out and the number of cars whose whereabouts are unknown are compared, but where there is still one missing, it means that there are still cars and people buried under the earth, and the rescue can not be stopped.
Is it technically difficult to get the data of this "unaccounted for" vehicle? It should not be difficult at all.
Every highway intersection has a lot of cameras with different angles, and almost every camera has a license plate recognition capability. Even if the highway is free during the May Day period, every car has to pass through the toll station bayonet to be recorded, and no car can leap over without leaving a trace.
With such a convenient high-tech means, it is supposed to extract data for the first time to guide the accident rescue, how can you still rely on excavators and shovels to dig out one by one to know how serious the accident is?
This is a question of whether the public can get the security of their private information in exchange for the government after handing it over to the government.
Now there are cameras everywhere on the highway, and you can get a fine if you exceed the speed limit, and you can get a fine when you drive on the phone, which is of course good and helps to ensure driving safety. But at the same time, a car doesn't come out the next day after entering the highway, so there's no reason to say you don't know, right?
It makes sense for the public to demand the role of cameras when the public has access to the private information of vehicles and people for the sake of public safety, right?
In recent years, local governments have spent huge sums of money to purchase and build smart city systems, one of the goals is to accurately control road traffic data information. When dozens of lives were buried by landslides, how could we go back to the primitive era of digging up and counting one by one? This is very undeserved.
There is another point that I dare not say clearly, how many vehicles have fallen on the Meida Expressway, and the relevant departments do not grasp it, or do they not want to grasp it?
A little constructive advice:
There are cameras at the high-speed toll stations, and there is also the world's top traffic big data intelligent analysis system behind it. If there's an accident, use them.
