As a native of Wuhan ya, because the work is also in Wuhan, I did not leave home during the epidemic, the genuineness feel the impact of the new virus crown of life and physical and mental.
because of the epidemic in the hardest hit, I know that emotional over infected each other, is not conducive to physical and mental health, so in this article I will try to be fair and objective analysis of automobile travel the challenges encountered.
To minimize the spread of the virus, Wuhan public transport substantially in a closed state. The following example is based on some of my own friends and relatives true feelings, there is no choice there is also grateful to panic. The rapid development of the epidemic, we hope some of my experience and knowledge to master the car to give you some help.
real-time data February 3, the case is still rising

now the city of Wuhan travel difficult?
Even today the tenth day, the country has resumed in many cities, but in the city of Wuhan travel or hard, with only a handful of several communities car can not guarantee that every car needs of members. For example, the other day there are children and relatives sudden illness requiring hospitalization, but not within the city because car community responsibility issues, ineffective communication after only think of ways to go to the hospital on their own.
Fortunately, Wuhan taxi operators still have a part (and not subject to fees), as well as some private cars can still travel, fortunately no great delays in treatment (available it took more than half an hour wait in the car).
Because of this emergency, II think about our car network service providers should come forward to help solve the problem. Because the provisions of the municipal government of Wuhan, at this stage we can not call taxis and other networks about cars through online platforms, if you can not contact a friend to a car, and others willing to help pick, it only luck.
such as drops, tick, T3 and travel east about car service network have been suspended.
we can understand that this is not chaos in response to the call, but the outbreak of the epidemic in the affected areas and still have to go out of the car, is really not to. But as of this writing, I still fail to see related support calls about car platform network should no longer active more. For example, after the No. January 24 network outage about cars, drivers have to travel east Registration emergency team set up, mainly to escort the medical staff, can be considered to alleviate some of the pressure.
Of course, this is only emergencies, we can not be too hard, now do not go out, he was right to protect themselves, their families and contribute to the country’s largest. May I know, the car needs Wuhan surrounding area more difficult, so it should be established whether these non-epidemic emergency response mechanism as soon as possible of it?
As far as I know, some villages will now entertain such vehicles demand. It must occupy a car pneumonia resources, but this is a last resort.

the next quarter, car travel by what impact?
according to plan around, basically after February 14 will end before the Chinese New Year holiday. But some analysts have been parties to prove, so after this battle might want to May. For some time, public transport will face veryBig challenge.
analysis that, in order to minimize aggregation, demand for cars will be up, and I agree with the basic hold.
In recent days many of my friends received a telephone consultation, you want to help us to see there are no resources to purchase, to minimize costs and do not go out you can directly purchase, and home delivery. Group of friends, mostly car-free households, small part because of the way both spouses work does not need to buy a second car.
But if just from the historical data to infer the current demand for cars, there will be some deviation.
For example, some Internet companies to minimize aggregation, has been trying to work online. And all these years, people debt ratio rising (in 2019, the debt ratio up to 107 percentage of residents), plus after the outbreak continued downward economy, many people can not take the weight of the car.
or take the city of Wuhan, the family even if not sick, this time alone buy medicine protective equipment, generally less than 5,000 yuan, the future will continue spending . Not to mention some of the sick but not diagnosed families, such as the case in the figure below, the high treatment costs the average family is difficult to afford.
in respect of a joint venture car company where the author’s view, basically in half shutdown state, the future of a quarter did not dare under heavy index, can only go step by step. So in the case of supply and demand have pressure, the new car market is still unknown whether there are boosted.
the face of heavy pressure, sure about car network would assume important responsibilities in the next quarter. Compared to buying a car, spend thousands of dollars a taxi is the most logical choice, and this is my opinion at the moment than to the advantage of the SARS period.
can be bad news this time is always a lot of, like my uncle is volunteer Wuhan community, because the patient transfers, and he is unfortunate enough to be infected, and fortunately the situation is not serious, are in home quarantine .
so as to talk of the beginning, our net about car platform should be ready as early as possible, how to protect the driver, how to establish a reasonable car and certification policy. Such as body temperature to the driver with a gun, you must check the temperature before the passengers on the train? But from February 14 to 10 days, and you can not fight the battle unprepared ah.

car filter system could help it?
did not think, in 2020 turned out to be the most difficult things to buy masks.
N95 / KN95 unthinkable, ordinary surgical masks buy is to make, no one would dare feel bad money. At this juncture, some car companies to promote their advantages in automobile safety, it is not really reliable it?
Here we have to be aware of two issues.
1. How is the virus spread?
2. Features car air purification system is what?
dissemination of new crown virus mechanisms, we know that it has the following characteristics:
1) virus because of their metabolic system, after only infect other biological cells, use on behalf of the infected cellsXie system to replicate. In other words, after leaving the organism, the virus can not survive for too long independence. Novel coronavirus survival time in a dry environment at approximately 48 hours and after 2 hours through the air, the activity decreased significantly (but still contagious).
– the car as a confined space, can really help us physically isolated.
2) The virus is mainly spread by droplets, and the propagation velocity and scope of the quite amazing. When sneezing, it can have a tremendous propulsion speeds up to 44m / s, more than 40,000 dispersed into individual droplets, each droplet having a large number of bacteria and viruses. The latest study found that Massachusetts Institute of Technology, a medium-sized sneeze droplets contaminated by just a few minutes the whole room (about 10 cubic meters).
– If you do not wear masks, the sneeze in the car means that every car will be affected.
3) can rely on airborne viruses may depend on a number of floating in the air medium, the medium is a dust (diameter generally gt; 5 microns) or fly foam core (≤5 microns). Coughing diameter droplet nuclei produced universal (82 percent) 0.74 to 2.12 microns concentrated.
– the virus is dependent on minimal medium.
that we often say that the car air purification system, its work is characterized by what it?
we get GM the HEPA filter and negative ion generator design example, the air filter PM2.5 PM2.5 particles can effectively block, and can filter out 99% or more diameter between air pollution particulates between 0.3 to 10 microns, the mean droplet adhered / droplet nuclei virus can hardly flowInto the car.
As for negative ion generator, the passenger compartment can effectively reduce airborne dust, dirt particles as well as pollen, but also remove a variety of odors including including tobacco.
Or Tesla’s “biological and chemical weapons defense mode”, two minutes, it will reduce the value of PM2.5 car to not only monitor the level.
That is not to say that what we really safe?
there are still some problems. For example:
1) through the filter with a lysis whether the material is critical. Just virus can only survive in a dry environment 48h, if the environment is bad, the survival time will be longer. The lytic material can inhibit the growth of bacteria, avoid filters become breeding ground for bacteria, causing secondary pollution.
2) negative ions known as “air vitamin”, have a good effect on air pollution, including the removal of PM2.5, including, but not kill germs or bacteria spores, viruses, fungi and the like.
3) PM2.5 air filter designed to have a good air-tight, air will bypass the filter or filtering effect lost. Car out of gas systems because the characteristics of the assembly, it is difficult to achieve an absolute seal. But because there is a certain suction pressure (working pressure of the air conditioning system is about 200-500pa), also increase the risk of inhalation of the virus.
To sum up, models containing PM2.5 car air purification system to really give us some help, but it can not expect to have to wear a mask, but never not. In addition, we recommend you to regularly disinfect the car, especially filters and regular contact with parts of the hand to pay attention.
Yasi Dun Summary
we should not be too intoxicated man’s conquest of nature, each such victory nature takes its revenge on us. Thank health care workers and the public encounter difficulties difficulties, I believe we all contribute energy, we will usher in a better tomorrow.
as a car people, these are my observations and thinking, I hope we can talk about the message your insights.
