The release sequence of traffic lights is not completely uniform, it needs to be determined according to the traffic volume at the intersection. However, at present, the traffic in most cities in the country follows the principle of “go straight first and turn left”.
In the past, according to the different local circulation, the order of traffic signal release was that some vehicles were allowed to turn left first, and some were allowed to go straight first. For a long time, the left-turning lane is often regarded as a “straight lane”. If a left-turning vehicle grabs the “green light tail”, it will also disrupt the driving of the straight-going vehicle. This situation is common during rush hours. The emergence of this situation makes it difficult for drivers to grasp and brings a lot of inconvenience.
However, in order to meet the needs of modern urban transportation development, ease the pressure of increasing urban traffic flow, and provide a convenient, fast and unobstructed traffic environment for citizens to travel to a greater extent, at the end of 2014, many traffic lights within the urban area The order of release has been uniformly adjusted to “go straight first and then turn left”. After the implementation of the method of “go straight first and turn left”, the problem of “inefficient left turn” will be effectively solved. It can also reduce traffic conflict points while increasing the road traffic rate and improve the safety factor of the intersection.
Of course, when traveling, in addition to fully understanding the order of traffic signal release, attention should also be paid to the lighting rules of traffic lights. As long as these two aspects are fully understood, the smooth flow of traffic can be better guaranteed.
