The traffic police woke up the drivers along the way for 7 hours and 7 kilometers. What inconvenience did the heavy snow bring to the traffic?

Every winter, people's traffic will always have some problems, because it is particularly prone to heavy snow or other extreme weather in winter, so people's travel will be greatly hindered. Therefore, if you want to travel in winter, you must pay attention to the weather forecast and try not to travel in extreme weather to avoid traffic jams on the road. On a snowy day in 2020, the traffic police worked continuously on the expressway for 7 hours, waking up as many as 100 drivers back and forth, because if people are stuck in traffic jams on the road, the time will be very long, and many drivers will be a little tired and choose to rest on the road. However, if you rest in such extreme weather, there will be accidents. Therefore, when resting, someone must observe the surrounding situation clearly and wake up the drivers in time to react. Let me briefly talk about the inconvenience caused by heavy snow.

First, causing traffic jams in snowy days, the most common traffic phenomenon is traffic jams, because the accumulation of heavy snow will make some sections of the road unable to pass normally, resulting in traffic jams on this section and unable to turn around and change lanes. This will form a vicious circle and make the traffic more and more crowded. The normal phenomenon will usually be congested for three or four hours, which requires the traffic police to clear it, but it is also very difficult.

Second, the probability of car accidents has increased. Because the weather is cold when it snows, the snow in some sections will become very hard and smooth after being crushed by vehicles, and the cold weather will make the vehicles unable to brake in time when driving, thus causing car accidents. The probability of every car accident in extreme weather is greatly increased, which brings great obstacles to traffic and great threats to people's life safety.

Third, people's travel efficiency is greatly reduced. Most people travel on snowy days for some purpose. Basically, no one will travel in this extreme weather, but these extreme weather have brought great inconvenience to these purposeful people, greatly prolonged their travel time and greatly affected people's travel efficiency. So winter is the worst season for traffic environment. In extreme weather, if people don't have to do anything necessary, they will try their best to reduce traffic pressure and some burdens, and they can also ensure their own lives.
