Traffic lights in many cities don't count seconds. What is the reason?

Traffic lights in many cities don't count seconds. What is the reason? Cars have become the most important road transport in urban traffic, and the urban traffic volume is very large. This is because there are too many cars in urban traffic and the traffic order is not good, so the traffic department has set up a lot of monitoring and management equipment and road passes to create traffic on urban roads.

Everyone should often see these devices and signs to help manage the daily traffic, which is an important part of road traffic rules. Without them, the traffic order in the city would be chaotic. I believe everyone should know more about the traffic lights. After all, we pass the traffic lights almost every day. This is an important means to divert traffic and pedestrians. Almost all of them are listed in traffic lights in most cities. Car owners and pedestrians can make preparations in advance according to the seconds of traffic lights, which also improves the traffic flow to some extent. But at present, some cities cancel the second traffic light. It is considered that there are still some shortcomings in this traffic light, which may endanger the personal safety of car owners and pedestrians. It's intuitive to see the traffic lights. Why did some cities cancel? This is really hard!

In the original traffic lights, pedestrians and car owners decided how much time by looking at the seconds on the red and green indicator lights. You can cross the intersection before this, and you can pass the green light directly in front of you. Although this method is efficient, it is easy to cause traffic accidents. Some car owners or pedestrians, when they see the green light, don't want to wait for the traffic lights, and just accelerate the intersection. If the green light suddenly turns red when passing through the intersection, it may collide with other vehicles or pedestrians, causing irreparable harm.

If the traffic lights are deleted, the traffic can only be displayed in color in front of everyone. We don't know when the lights will change, so everyone has little time to face the traffic lights. Increase the situation, which can also prevent traffic accidents to some extent. Although watching traffic lights will affect the passivity of intersections, this effect is not great. The most important thing is to help everyone's safety, which is the main reason to get rid of traffic lights.
