What are the types of traffic lights
Author:
There are seven main types of traffic signals, namely motor vehicle signals, non motor vehicle signals, pedestrian crossing signals, lane signals, direction indicators, flashing warning signals, and road and railway level intersection signals.
Motor vehicle signal lights consist of circular units with three patterns of red, yellow, and green, guiding motor vehicles to pass.
There is a bicycle pattern inside the non motorized vehicle signal light, which also has red, yellow, and green colors to guide non motorized vehicles through.
The lane signal lights consist of fork shaped and arrow patterns, indicating the movement of vehicles in this lane.
The flashing warning signal light is a continuously flashing yellow light that reminds vehicles and pedestrians to keep an eye out before passing.
The pedestrian crossing signal lights have red pedestrian standing and green pedestrian walking patterns to guide pedestrians.
The direction indicator lights have arrow patterns inside, indicating the direction of motor vehicle travel, such as left turn, straight ahead, or right turn.
When the signal lights at the intersection of roads and railways alternate between two or one red light flashing or on, vehicles and pedestrians are prohibited from passing. If the red light goes out, passage is allowed.
In addition, traffic signals can be divided into two categories: vehicle traffic control lights and pedestrian crossing lights.
In the three colors of red, yellow, and green, vehicles and pedestrians are not allowed to pass when the red light is on, and vehicles should wait outside the parking line; When the yellow light is on, vehicles and pedestrians are not allowed to pass, but those who have crossed the parking line can continue to pass; Vehicles and pedestrians are allowed to pass when the green light is on.
Traffic lights play an important role in road traffic, effectively ensuring traffic safety and ensuring that motor vehicles, non motor vehicles, and pedestrians follow the lights without conflicting with each other.
