With the increase of the number of private cars on the road, this will lead to traffic congestion. In this case, people will waste more time. Moreover, because cars will continuously emit exhaust gas, the impact on environmental protection is also very great. To change this situation, people must be encouraged to travel by public transport, but many people are unwilling to take public transport. It is because the efficiency of public transportation is too low, and with the bus signal lights, the speed of public transportation will increase a lot. In this case, more and more people will naturally like the bus.
On the other hand, economic considerations are also very important. Although people's living standards have improved a lot now, the cost of traveling by private car is much higher than that of bus. If public transportation can be implemented, it will play a greater role in improving people's quality of life, and at the same time the cost can be reduced a lot.
It is precisely because bus travel has so many benefits for ordinary people that the country will vigorously promote this way now, and when implementing this way, although various attempts will be made, such as bus special signal lights.
